Re-factored system states and alarm management. Serial baud support greater than 57600. - Refactored system states to be more clear and concise. Alarm locks processes when position is unknown to indicate to user something has gone wrong. - Changed mc_alarm to mc_reset, which now manages the system reset function. Centralizes it. - Renamed '$X' kill homing lock to kill alarm lock. - Created an alarm error reporting method to clear up what is an alarm: message vs a status error: message. For GUIs mainly. Alarm codes are negative. Status codes are positive. - Serial baud support upto 115200. Previous baudrate calc was unstable for 57600 and above. - Alarm state locks out all g-code blocks, including startup scripts, but allows user to access settings and internal commands. For example, to disable hard limits, if they are problematic. - Hard limits do not respond in an alarm state. - Fixed a problem with the hard limit interrupt during the homing cycle. The interrupt register is still active during the homing cycle and still signal the interrupt to trigger when re-enabled. Instead, just disabled the register. - Homing rate adjusted. All axes move at homing seek rate, regardless of how many axes move at the same time. This is unlike how the stepper module does it as a point to point rate. - New config.h settings to disable the homing rate adjustment and the force homing upon powerup. - Reduced the number of startup lines back down to 2 from 3. This discourages users from placing motion block in there, which can be very dangerous. - Startup blocks now run only after an alarm-free reset or after a homing cycle. Does not run when $X kill is called. For satefy reasons

Grbl v1.0e huge beta release. Overrides and new reporting. - Feature: Realtime feed, rapid, and spindle speed overrides. These alter the running machine state within tens of milliseconds! - Feed override: 100%, +/-10%, +/-1% commands with values 1-200% of programmed feed - Rapid override: 100%, 50%, 25% rapid rate commands - Spindle speed override: 100%, +/-10%, +/-1% commands with values 50-200% of programmed speed - Override values have configurable limits and increments in config.h. - Feature: Realtime toggle overrides for spindle stop, flood coolant, and optionally mist coolant - Spindle stop: Enables and disables spindle during a feed hold. Automatically restores last spindles state. - Flood and mist coolant: Immediately toggles coolant state until next toggle or g-code coolant command. - Feature: Jogging mode! Incremental and absolute modes supported. - Grbl accepts jogging-specific commands like $J=X100F50. An axis word and feed rate are required. G20/21 and G90/G91 commands are accepted. - Jog motions can be canceled at any time by a feed hold `!` command. The buffer is automatically flushed. (No resetting required). - Jog motions do not alter the g-code parser state so GUIs don’t have to track what they changed and correct it. - Feature: Laser mode setting. Allows Grbl to execute continuous motions with spindle speed and state changes. - Feature: Significantly improved status reports. Overhauled to cram in more meaningful data and still make it smaller on average. - All available data is now sent by default, but does not appear if it doesn’t change or is not active. - Machine position(MPos) or work position(WPos) is reported but not both at the same time. Instead, the work coordinate offsets (WCO)are sent intermittently whenever it changes or refreshes after 10-30 status reports. Position vectors are easily computed by WPos = MPos - WCO. - All data has changed in some way. Details of changes are in the markdown documents and wiki. - Feature: 16 new realtime commands to control overrides. All in extended-ASCII character space. - While they are not easily typeable and requires a GUI, they can’t be accidentally triggered by some latent character in the g-code program and have tons of room for expansion. - Feature: New substates for HOLD and SAFETY DOOR. A `:x` is appended to the state, where `x` is an integer and indicates a substate. - For example, each integer of a door state describes in what phase the machine is in during parking. Substates are detailed in the documentation. - Feature: With the alarm codes, homing and probe alarms have been expanded with more codes to provide more exact feedback on what caused the alarm. - Feature: New hard limit check upon power-up or reset. If detected, a feedback message to check the limit switches sent immediately after the welcome message. - May be disabled in config.h. - OEM feature: Enable/disable `$RST=` individual commands based on desired behavior in config.h. - OEM feature: Configurable EEPROM wipe to prevent certain data from being deleted during firmware upgrade to a new settings version or `RST=*` command. - OEM feature: Enable/disable the `$I=` build info write string with external EEPROM write example sketch. - This prevents a user from altering the build info string in EEPROM. This requires the vendor to write the string to EEPROM via external means. An Arduino example sketch is provided to accomplish this. This would be useful for contain product data that is retrievable. - Tweak: All feedback has been drastically trimmed to free up flash space for the v1.0 release. - The `$` help message is just one string, listing available commands. - The `$$` settings printout no longer includes descriptions. Only the setting values. (Sorry it’s this or remove overrides!) - Grbl `error:` and `ALARM:` responses now only contain codes. No descriptions. All codes are explained in documentation. - Grbl’s old feedback style may be restored via a config.h, but keep in mind that it will likely not fit into the Arduino’s flash space. - Tweak: Grbl now forces a buffer sync or stop motion whenever a g-code command needs to update and write a value to EEPROM or changes the work coordinate offset. - This addresses two old issues in all prior Grbl versions. First, an EEPROM write requires interrupts to be disabled, including stepper and serial comm. Steps can be lost and data can be corrupted. Second, the work position may not be correlated to the actual machine position, since machine position is derived from the actual current execution state, while work position is based on the g-code parser offset state. They are usually not in sync and the parser state is several motions behind. This forced sync ensures work and machine positions are always correct. - This behavior can be disabled through a config.h option, but it’s not recommended to do so. - Tweak: To make status reports standardized, users can no longer change what is reported via status report mask, except for only toggling machine or work positions. - All other data fields are included in the report and can only be disabled through the config.h file. It’s not recommended to alter this, because GUIs will be expecting this data to be present and may not be compatible. - Tweak: Homing cycle and parking motion no longer report a negative line number in a status report. These will now not report a line number at all. - Tweak: New `[Restoring spindle]` message when restoring from a spindle stop override. Provides feedback what Grbl is doing while the spindle is powering up and a 4.0 second delay is enforced. - Tweak: Override values are reset to 100% upon M2/30. This behavior can be disabled in config.h - Tweak: The planner buffer size has been reduced from 18 to 16 to free up RAM for tracking and controlling overrides. - Tweak: TX buffer size has been increased from 64 to 90 bytes to improve status reporting and overall performance. - Tweak: Removed the MOTION CANCEL state. It was redundant and didn’t affect Grbl’s overall operation by doing so. - Tweak: Grbl’s serial buffer increased by +1 internally, such that 128 bytes means 128, not 127 due to the ring buffer implementation. Long overdue. - Tweak: Altered sys.alarm variable to be set by alarm codes, rather than bit flags. Simplified how it worked overall. - Tweak: Planner buffer and serial RX buffer usage has been combined in the status reports. - Tweak: Pin state reporting has been refactored to report only the pins “triggered” and nothing when not “triggered”. - Tweak: Current machine rate or speed is now included in every report. - Tweak: The work coordinate offset (WCO) and override states only need to be refreshed intermittently or reported when they change. The refresh rates may be altered for each in the config.h file with different idle and busy rates to lessen Grbl’s load during a job. - Tweak: For temporary compatibility to existing GUIs until they are updated, an option to revert back to the old style status reports is available in config.h, but not recommended for long term use. - Tweak: Removed old limit pin state reporting option from config.h in lieu of new status report that includes them. - Tweak: Updated the defaults.h file to include laser mode, altered status report mask, and fix an issue with a missing invert probe pin default. - Refactor: Changed how planner line data is generated and passed to the planner and onto the step generator. By making it a struct variable, this saved significant flash space. - Refactor: Major re-factoring of the planner to incorporate override values and allow for re-calculations fast enough to immediately take effect during operation. No small feat. - Refactor: Re-factored the step segment generator for re-computing new override states. - Refactor: Re-factored spindle_control.c to accommodate the spindle speed overrides and laser mode. - Refactor: Re-factored parts of the codebase for a new jogging mode. Still under development though and slated to be part of the official v1.0 release. Hang tight. - Refactor: Created functions for computing a unit vector and value limiting based on axis maximums to free up more flash. - Refactor: The spindle PWM is now set directly inside of the stepper ISR as it loads new step segments. - Refactor: Moved machine travel checks out of soft limits function into its own since jogging uses this too. - Refactor: Removed coolant_stop() and combined with coolant_set_state(). - Refactor: The serial RX ISR forks off extended ASCII values to quickly assess the new override realtime commands. - Refactor: Altered some names of the step control flags. - Refactor: Improved efficiency of the serial RX get buffer count function. - Refactor: Saved significant flash by removing and combining print functions. Namely the uint8 base10 and base2 functions. - Refactor: Moved the probe state check in the main stepper ISR to improve its efficiency. - Refactor: Single character printPgmStrings() went converted to direct serial_write() commands to save significant flash space. - Documentation: Detailed Markdown documents on error codes, alarm codes, messages, new real-time commands, new status reports, and how jogging works. More to come later and will be posted on the Wiki as well. - Documentation: CSV files for quick importing of Grbl error and alarm codes. - Bug Fix: Applied v0.9 master fixes to CoreXY homing. - Bug Fix: The print float function would cause Grbl to crash if a value was 1e6 or greater. Increased the buffer by 3 bytes to help prevent this in the future. - Bug Fix: Build info and startup string EEPROM restoring was not writing the checksum value. - Bug Fix: Corrected an issue with safety door restoring the proper spindle and coolant state. It worked before, but breaks with laser mode that can continually change spindle state per planner block. - Bug Fix: Move system position and probe position arrays out of the system_t struct. Ran into some compiling errors that were hard to track down as to why. Moving them out fixed it.

Bug fix for certain motions. Re-org of includes. - Critical bug fix for diagonal motions that continue on the same direction or return in the exact opposite direction. This issue could cause Grbl to crash intermittently due to a numerical round-off error. Grbl versions prior to v0.9g shouldn’t have this issue. - Reorganized all of the includes used by Grbl. Centralized it into a single “grbl.h” include. This will help simplify the compiling and uploading process through the Arduino IDE. - Added an example .INO file for users to simply open and run when compiling and uploading through the IDE. More to come later.

Second, the work position may not be correlated to the actual machine position, since machine position is derived from the actual current execution state, while work position is based on the g-code parser offset state. They are usually not in sync and the parser state is several motions behind. This forced sync ensures work and machine positions are always correct. - This behavior can be disabled through a config.h option, but it’s not recommended to do so. - Tweak: To make status reports standardized, users can no longer change what is reported via status report mask, except for only toggling machine or work positions. - All other data fields are included in the report and can only be disabled through the config.h file. It’s not recommended to alter this, because GUIs will be expecting this data to be present and may not be compatible. - Tweak: Homing cycle and parking motion no longer report a negative line number in a status report. These will now not report a line number at all. - Tweak: New `[Restoring spindle]` message when restoring from a spindle stop override. Provides feedback what Grbl is doing while the spindle is powering up and a 4.0 second delay is enforced. - Tweak: Override values are reset to 100% upon M2/30. This behavior can be disabled in config.h - Tweak: The planner buffer size has been reduced from 18 to 16 to free up RAM for tracking and controlling overrides. - Tweak: TX buffer size has been increased from 64 to 90 bytes to improve status reporting and overall performance. - Tweak: Removed the MOTION CANCEL state. It was redundant and didn’t affect Grbl’s overall operation by doing so. - Tweak: Grbl’s serial buffer increased by +1 internally, such that 128 bytes means 128, not 127 due to the ring buffer implementation. Long overdue. - Tweak: Altered sys.alarm variable to be set by alarm codes, rather than bit flags. Simplified how it worked overall. - Tweak: Planner buffer and serial RX buffer usage has been combined in the status reports. - Tweak: Pin state reporting has been refactored to report only the pins “triggered” and nothing when not “triggered”. - Tweak: Current machine rate or speed is now included in every report. - Tweak: The work coordinate offset (WCO) and override states only need to be refreshed intermittently or reported when they change. The refresh rates may be altered for each in the config.h file with different idle and busy rates to lessen Grbl’s load during a job. - Tweak: For temporary compatibility to existing GUIs until they are updated, an option to revert back to the old style status reports is available in config.h, but not recommended for long term use. - Tweak: Removed old limit pin state reporting option from config.h in lieu of new status report that includes them. - Tweak: Updated the defaults.h file to include laser mode, altered status report mask, and fix an issue with a missing invert probe pin default. - Refactor: Changed how planner line data is generated and passed to the planner and onto the step generator. By making it a struct variable, this saved significant flash space. - Refactor: Major re-factoring of the planner to incorporate override values and allow for re-calculations fast enough to immediately take effect during operation. No small feat. - Refactor: Re-factored the step segment generator for re-computing new override states. - Refactor: Re-factored spindle_control.c to accommodate the spindle speed overrides and laser mode. - Refactor: Re-factored parts of the codebase for a new jogging mode. Still under development though and slated to be part of the official v1.0 release. Hang tight. - Refactor: Created functions for computing a unit vector and value limiting based on axis maximums to free up more flash. - Refactor: The spindle PWM is now set directly inside of the stepper ISR as it loads new step segments. - Refactor: Moved machine travel checks out of soft limits function into its own since jogging uses this too. - Refactor: Removed coolant_stop() and combined with coolant_set_state(). - Refactor: The serial RX ISR forks off extended ASCII values to quickly assess the new override realtime commands. - Refactor: Altered some names of the step control flags. - Refactor: Improved efficiency of the serial RX get buffer count function. - Refactor: Saved significant flash by removing and combining print functions. Namely the uint8 base10 and base2 functions. - Refactor: Moved the probe state check in the main stepper ISR to improve its efficiency. - Refactor: Single character printPgmStrings() went converted to direct serial_write() commands to save significant flash space. - Documentation: Detailed Markdown documents on error codes, alarm codes, messages, new real-time commands, new status reports, and how jogging works. More to come later and will be posted on the Wiki as well. - Documentation: CSV files for quick importing of Grbl error and alarm codes. - Bug Fix: Applied v0.9 master fixes to CoreXY homing. - Bug Fix: The print float function would cause Grbl to crash if a value was 1e6 or greater. Increased the buffer by 3 bytes to help prevent this in the future. - Bug Fix: Build info and startup string EEPROM restoring was not writing the checksum value. - Bug Fix: Corrected an issue with safety door restoring the proper spindle and coolant state. It worked before, but breaks with laser mode that can continually change spindle state per planner block. - Bug Fix: Move system position and probe position arrays out of the system_t struct. Ran into some compiling errors that were hard to track down as to why. Moving them out fixed it.

protocol_buffer_synchronize(); // A startup line may contain a motion and be executing.
#endif
Probing cycle and view build info bug fixes. - Probing cycle would drop into a QUEUED state, if multiple G38.2 are sent. It would not honor the auto cycle start flags. To fix, the auto cycle start state is saved at the beginning of the probing cycle and restored at the end, since the feed hold it uses to stop a triggered probe will disable the auto start flag. For now it’s a patch, rather than a permanent fix. - protocol_buffer_synchronize() also has a failure case. Auto cycle start does not get executed when the system is waiting in here, so if it’s in a QUEUED state already, it won’t resume. Patched here, but not fully resolved. - Fixed a problem with the “view build info” command. The EEPROM write would do weird things and corrupt the EEPROM. Not sure exactly what caused it, but it’s likely a compiler problem with an improperly defined EEPROM address. It didn’t have enough room to store a full string. To fix, the build info EEPROM range was increased and the max number of STARTUP_BLOCKS was reduced to 2 from 3. - Lastly, when a $I view build info is used for the first time, it would normally show an EEPROM read error, since it wasn’t cleared or wasn’t therein the first place. It will now not show that error. A patch rather than a permanent fix again.

Re-factored system states and alarm management. Serial baud support greater than 57600. - Refactored system states to be more clear and concise. Alarm locks processes when position is unknown to indicate to user something has gone wrong. - Changed mc_alarm to mc_reset, which now manages the system reset function. Centralizes it. - Renamed '$X' kill homing lock to kill alarm lock. - Created an alarm error reporting method to clear up what is an alarm: message vs a status error: message. For GUIs mainly. Alarm codes are negative. Status codes are positive. - Serial baud support upto 115200. Previous baudrate calc was unstable for 57600 and above. - Alarm state locks out all g-code blocks, including startup scripts, but allows user to access settings and internal commands. For example, to disable hard limits, if they are problematic. - Hard limits do not respond in an alarm state. - Fixed a problem with the hard limit interrupt during the homing cycle. The interrupt register is still active during the homing cycle and still signal the interrupt to trigger when re-enabled. Instead, just disabled the register. - Homing rate adjusted. All axes move at homing seek rate, regardless of how many axes move at the same time. This is unlike how the stepper module does it as a point to point rate. - New config.h settings to disable the homing rate adjustment and the force homing upon powerup. - Reduced the number of startup lines back down to 2 from 3. This discourages users from placing motion block in there, which can be very dangerous. - Startup blocks now run only after an alarm-free reset or after a homing cycle. Does not run when $X kill is called. For satefy reasons

Lots of re-organization and cleaning-up. Some bug fixes. - Added a new source and header file called system. These files contain the system commands and variables, as well as all of the system headers and standard libraries Grbl uses. Centralizing some of the code. - Re-organized the include headers throughout the source code. - ENABLE_M7 define was missing from config.h. Now there. - SPINDLE_MAX_RPM and SPINDLE_MIN_RPM now defined in config.h. No uncommenting to prevent user issues. Minimum spindle RPM now provides the lower, near 0V, scale adjustment, i.e. some spindles can go really slow so why use up our 256 voltage bins for them? - Remove some persistent variables from coolant and spindle control. They were redundant. - Removed a VARIABLE_SPINDLE define in cpu_map.h that shouldn’t have been there. - Changed the DEFAULT_ARC_TOLERANCE to 0.002mm to improve arc tracing. Before we had issues with performance, no longer. - Fixed a bug with the hard limits and the software debounce feature enabled. The invert limit pin setting wasn’t honored. - Fixed a bug with the homing direction mask. Now is like it used to be. At least for now. - Re-organized main.c to serve as only as the reset/initialization routine. Makes things a little bit clearer in terms of execution procedures. - Re-organized protocol.c as the overall master control unit for execution procedures. Not quite there yet, but starting to make a little more sense in how things are run. - Removed updating of old settings records. So many new settings have been added that it’s not worth adding the code to migrate old user settings. - Tweaked spindle_control.c a bit and made it more clear and consistent with other parts of Grbl. - Tweaked the stepper disable bit code in stepper.c. Requires less flash memory.

New build info feature. (per @Analogreality request) - New build info feature. Hidden command ‘$I’ will print the build info for your Grbl firmware. Users may also write an identifying message within it via ‘$I=‘ with up to 32 characters. (no more, or else it will break). - Adjusted the max number of startup lines to 3. Majority of people will only need one. - Fixed a compile error with spindle_control.c. A rogue #endif was causing problems.

// Method to store build info into EEPROM
Grbl v1.0e huge beta release. Overrides and new reporting. - Feature: Realtime feed, rapid, and spindle speed overrides. These alter the running machine state within tens of milliseconds! - Feed override: 100%, +/-10%, +/-1% commands with values 1-200% of programmed feed - Rapid override: 100%, 50%, 25% rapid rate commands - Spindle speed override: 100%, +/-10%, +/-1% commands with values 50-200% of programmed speed - Override values have configurable limits and increments in config.h. - Feature: Realtime toggle overrides for spindle stop, flood coolant, and optionally mist coolant - Spindle stop: Enables and disables spindle during a feed hold. Automatically restores last spindles state. - Flood and mist coolant: Immediately toggles coolant state until next toggle or g-code coolant command. - Feature: Jogging mode! Incremental and absolute modes supported. - Grbl accepts jogging-specific commands like $J=X100F50. An axis word and feed rate are required. G20/21 and G90/G91 commands are accepted. - Jog motions can be canceled at any time by a feed hold `!` command. The buffer is automatically flushed. (No resetting required). - Jog motions do not alter the g-code parser state so GUIs don’t have to track what they changed and correct it. - Feature: Laser mode setting. Allows Grbl to execute continuous motions with spindle speed and state changes. - Feature: Significantly improved status reports. Overhauled to cram in more meaningful data and still make it smaller on average. - All available data is now sent by default, but does not appear if it doesn’t change or is not active. - Machine position(MPos) or work position(WPos) is reported but not both at the same time. Instead, the work coordinate offsets (WCO)are sent intermittently whenever it changes or refreshes after 10-30 status reports. Position vectors are easily computed by WPos = MPos - WCO. - All data has changed in some way. Details of changes are in the markdown documents and wiki. - Feature: 16 new realtime commands to control overrides. All in extended-ASCII character space. - While they are not easily typeable and requires a GUI, they can’t be accidentally triggered by some latent character in the g-code program and have tons of room for expansion. - Feature: New substates for HOLD and SAFETY DOOR. A `:x` is appended to the state, where `x` is an integer and indicates a substate. - For example, each integer of a door state describes in what phase the machine is in during parking. Substates are detailed in the documentation. - Feature: With the alarm codes, homing and probe alarms have been expanded with more codes to provide more exact feedback on what caused the alarm. - Feature: New hard limit check upon power-up or reset. If detected, a feedback message to check the limit switches sent immediately after the welcome message. - May be disabled in config.h. - OEM feature: Enable/disable `$RST=` individual commands based on desired behavior in config.h. - OEM feature: Configurable EEPROM wipe to prevent certain data from being deleted during firmware upgrade to a new settings version or `RST=*` command. - OEM feature: Enable/disable the `$I=` build info write string with external EEPROM write example sketch. - This prevents a user from altering the build info string in EEPROM. This requires the vendor to write the string to EEPROM via external means. An Arduino example sketch is provided to accomplish this. This would be useful for contain product data that is retrievable. - Tweak: All feedback has been drastically trimmed to free up flash space for the v1.0 release. - The `$` help message is just one string, listing available commands. - The `$$` settings printout no longer includes descriptions. Only the setting values. (Sorry it’s this or remove overrides!) - Grbl `error:` and `ALARM:` responses now only contain codes. No descriptions. All codes are explained in documentation. - Grbl’s old feedback style may be restored via a config.h, but keep in mind that it will likely not fit into the Arduino’s flash space. - Tweak: Grbl now forces a buffer sync or stop motion whenever a g-code command needs to update and write a value to EEPROM or changes the work coordinate offset. - This addresses two old issues in all prior Grbl versions.

// Build info can only be stored when state is IDLE.
New build info feature. (per @Analogreality request) - New build info feature. Hidden command ‘$I’ will print the build info for your Grbl firmware. Users may also write an identifying message within it via ‘$I=‘ with up to 32 characters. (no more, or else it will break). - Adjusted the max number of startup lines to 3. Majority of people will only need one. - Fixed a compile error with spindle_control.c. A rogue #endif was causing problems.

Lots of re-organization and cleaning-up. Some bug fixes. - Added a new source and header file called system. These files contain the system commands and variables, as well as all of the system headers and standard libraries Grbl uses. Centralizing some of the code. - Re-organized the include headers throughout the source code. - ENABLE_M7 define was missing from config.h. Now there. - SPINDLE_MAX_RPM and SPINDLE_MIN_RPM now defined in config.h. No uncommenting to prevent user issues. Minimum spindle RPM now provides the lower, near 0V, scale adjustment, i.e. some spindles can go really slow so why use up our 256 voltage bins for them? - Remove some persistent variables from coolant and spindle control. They were redundant. - Removed a VARIABLE_SPINDLE define in cpu_map.h that shouldn’t have been there. - Changed the DEFAULT_ARC_TOLERANCE to 0.002mm to improve arc tracing. Before we had issues with performance, no longer. - Fixed a bug with the hard limits and the software debounce feature enabled. The invert limit pin setting wasn’t honored. - Fixed a bug with the homing direction mask. Now is like it used to be. At least for now. - Re-organized main.c to serve as only as the reset/initialization routine. Makes things a little bit clearer in terms of execution procedures. - Re-organized protocol.c as the overall master control unit for execution procedures. Not quite there yet, but starting to make a little more sense in how things are run. - Removed updating of old settings records. So many new settings have been added that it’s not worth adding the code to migrate old user settings. - Tweaked spindle_control.c a bit and made it more clear and consistent with other parts of Grbl. - Tweaked the stepper disable bit code in stepper.c. Requires less flash memory.

Re-factored system states and alarm management. Serial baud support greater than 57600. - Refactored system states to be more clear and concise. Alarm locks processes when position is unknown to indicate to user something has gone wrong. - Changed mc_alarm to mc_reset, which now manages the system reset function. Centralizes it. - Renamed '$X' kill homing lock to kill alarm lock. - Created an alarm error reporting method to clear up what is an alarm: message vs a status error: message. For GUIs mainly. Alarm codes are negative. Status codes are positive. - Serial baud support upto 115200. Previous baudrate calc was unstable for 57600 and above. - Alarm state locks out all g-code blocks, including startup scripts, but allows user to access settings and internal commands. For example, to disable hard limits, if they are problematic. - Hard limits do not respond in an alarm state. - Fixed a problem with the hard limit interrupt during the homing cycle. The interrupt register is still active during the homing cycle and still signal the interrupt to trigger when re-enabled. Instead, just disabled the register. - Homing rate adjusted. All axes move at homing seek rate, regardless of how many axes move at the same time. This is unlike how the stepper module does it as a point to point rate. - New config.h settings to disable the homing rate adjustment and the force homing upon powerup. - Reduced the number of startup lines back down to 2 from 3. This discourages users from placing motion block in there, which can be very dangerous. - Startup blocks now run only after an alarm-free reset or after a homing cycle. Does not run when $X kill is called. For satefy reasons

void settings_write_coord_data(uint8_t coord_select, float *coord_data, bool force, bool commit)
Grbl v1.0e huge beta release. Overrides and new reporting. - Feature: Realtime feed, rapid, and spindle speed overrides. These alter the running machine state within tens of milliseconds! - Feed override: 100%, +/-10%, +/-1% commands with values 1-200% of programmed feed - Rapid override: 100%, 50%, 25% rapid rate commands - Spindle speed override: 100%, +/-10%, +/-1% commands with values 50-200% of programmed speed - Override values have configurable limits and increments in config.h. - Feature: Realtime toggle overrides for spindle stop, flood coolant, and optionally mist coolant - Spindle stop: Enables and disables spindle during a feed hold. Automatically restores last spindles state. - Flood and mist coolant: Immediately toggles coolant state until next toggle or g-code coolant command. - Feature: Jogging mode! Incremental and absolute modes supported. - Grbl accepts jogging-specific commands like $J=X100F50. An axis word and feed rate are required. G20/21 and G90/G91 commands are accepted. - Jog motions can be canceled at any time by a feed hold `!` command. The buffer is automatically flushed. (No resetting required). - Jog motions do not alter the g-code parser state so GUIs don’t have to track what they changed and correct it. - Feature: Laser mode setting. Allows Grbl to execute continuous motions with spindle speed and state changes. - Feature: Significantly improved status reports. Overhauled to cram in more meaningful data and still make it smaller on average. - All available data is now sent by default, but does not appear if it doesn’t change or is not active. - Machine position(MPos) or work position(WPos) is reported but not both at the same time. Instead, the work coordinate offsets (WCO)are sent intermittently whenever it changes or refreshes after 10-30 status reports. Position vectors are easily computed by WPos = MPos - WCO. - All data has changed in some way. Details of changes are in the markdown documents and wiki. - Feature: 16 new realtime commands to control overrides. All in extended-ASCII character space. - While they are not easily typeable and requires a GUI, they can’t be accidentally triggered by some latent character in the g-code program and have tons of room for expansion. - Feature: New substates for HOLD and SAFETY DOOR. A `:x` is appended to the state, where `x` is an integer and indicates a substate. - For example, each integer of a door state describes in what phase the machine is in during parking. Substates are detailed in the documentation. - Feature: With the alarm codes, homing and probe alarms have been expanded with more codes to provide more exact feedback on what caused the alarm. - Feature: New hard limit check upon power-up or reset. If detected, a feedback message to check the limit switches sent immediately after the welcome message. - May be disabled in config.h. - OEM feature: Enable/disable `$RST=` individual commands based on desired behavior in config.h. - OEM feature: Configurable EEPROM wipe to prevent certain data from being deleted during firmware upgrade to a new settings version or `RST=*` command. - OEM feature: Enable/disable the `$I=` build info write string with external EEPROM write example sketch. - This prevents a user from altering the build info string in EEPROM. This requires the vendor to write the string to EEPROM via external means. An Arduino example sketch is provided to accomplish this. This would be useful for contain product data that is retrievable. - Tweak: All feedback has been drastically trimmed to free up flash space for the v1.0 release. - The `$` help message is just one string, listing available commands. - The `$$` settings printout no longer includes descriptions. Only the setting values. (Sorry it’s this or remove overrides!) - Grbl `error:` and `ALARM:` responses now only contain codes. No descriptions. All codes are explained in documentation. - Grbl’s old feedback style may be restored via a config.h, but keep in mind that it will likely not fit into the Arduino’s flash space. - Tweak: Grbl now forces a buffer sync or stop motion whenever a g-code command needs to update and write a value to EEPROM or changes the work coordinate offset. - This addresses two old issues in all prior Grbl versions. First, an EEPROM write requires interrupts to be disabled, including stepper and serial comm. Steps can be lost and data can be corrupted. Second, the work position may not be correlated to the actual machine position, since machine position is derived from the actual current execution state, while work position is based on the g-code parser offset state. They are usually not in sync and the parser state is several motions behind. This forced sync ensures work and machine positions are always correct. - This behavior can be disabled through a config.h option, but it’s not recommended to do so. - Tweak: To make status reports standardized, users can no longer change what is reported via status report mask, except for only toggling machine or work positions. - All other data fields are included in the report and can only be disabled through the config.h file. It’s not recommended to alter this, because GUIs will be expecting this data to be present and may not be compatible. - Tweak: Homing cycle and parking motion no longer report a negative line number in a status report. These will now not report a line number at all. - Tweak: New `[Restoring spindle]` message when restoring from a spindle stop override. Provides feedback what Grbl is doing while the spindle is powering up and a 4.0 second delay is enforced. - Tweak: Override values are reset to 100% upon M2/30. This behavior can be disabled in config.h - Tweak: The planner buffer size has been reduced from 18 to 16 to free up RAM for tracking and controlling overrides. - Tweak: TX buffer size has been increased from 64 to 90 bytes to improve status reporting and overall performance. - Tweak: Removed the MOTION CANCEL state. It was redundant and didn’t affect Grbl’s overall operation by doing so. - Tweak: Grbl’s serial buffer increased by +1 internally, such that 128 bytes means 128, not 127 due to the ring buffer implementation. Long overdue. - Tweak: Altered sys.alarm variable to be set by alarm codes, rather than bit flags. Simplified how it worked overall. - Tweak: Planner buffer and serial RX buffer usage has been combined in the status reports. - Tweak: Pin state reporting has been refactored to report only the pins “triggered” and nothing when not “triggered”. - Tweak: Current machine rate or speed is now included in every report. - Tweak: The work coordinate offset (WCO) and override states only need to be refreshed intermittently or reported when they change. The refresh rates may be altered for each in the config.h file with different idle and busy rates to lessen Grbl’s load during a job. - Tweak: For temporary compatibility to existing GUIs until they are updated, an option to revert back to the old style status reports is available in config.h, but not recommended for long term use. - Tweak: Removed old limit pin state reporting option from config.h in lieu of new status report that includes them. - Tweak: Updated the defaults.h file to include laser mode, altered status report mask, and fix an issue with a missing invert probe pin default. - Refactor: Changed how planner line data is generated and passed to the planner and onto the step generator. By making it a struct variable, this saved significant flash space. - Refactor: Major re-factoring of the planner to incorporate override values and allow for re-calculations fast enough to immediately take effect during operation. No small feat. - Refactor: Re-factored the step segment generator for re-computing new override states. - Refactor: Re-factored spindle_control.c to accommodate the spindle speed overrides and laser mode. - Refactor: Re-factored parts of the codebase for a new jogging mode. Still under development though and slated to be part of the official v1.0 release. Hang tight. - Refactor: Created functions for computing a unit vector and value limiting based on axis maximums to free up more flash. - Refactor: The spindle PWM is now set directly inside of the stepper ISR as it loads new step segments. - Refactor: Moved machine travel checks out of soft limits function into its own since jogging uses this too. - Refactor: Removed coolant_stop() and combined with coolant_set_state(). - Refactor: The serial RX ISR forks off extended ASCII values to quickly assess the new override realtime commands. - Refactor: Altered some names of the step control flags. - Refactor: Improved efficiency of the serial RX get buffer count function. - Refactor: Saved significant flash by removing and combining print functions. Namely the uint8 base10 and base2 functions. - Refactor: Moved the probe state check in the main stepper ISR to improve its efficiency. - Refactor: Single character printPgmStrings() went converted to direct serial_write() commands to save significant flash space. - Documentation: Detailed Markdown documents on error codes, alarm codes, messages, new real-time commands, new status reports, and how jogging works. More to come later and will be posted on the Wiki as well. - Documentation: CSV files for quick importing of Grbl error and alarm codes. - Bug Fix: Applied v0.9 master fixes to CoreXY homing. - Bug Fix: The print float function would cause Grbl to crash if a value was 1e6 or greater. Increased the buffer by 3 bytes to help prevent this in the future. - Bug Fix: Build info and startup string EEPROM restoring was not writing the checksum value. - Bug Fix: Corrected an issue with safety door restoring the proper spindle and coolant state. It worked before, but breaks with laser mode that can continually change spindle state per planner block. - Bug Fix: Move system position and probe position arrays out of the system_t struct. Ran into some compiling errors that were hard to track down as to why. Moving them out fixed it.

A `:x` is appended to the state, where `x` is an integer and indicates a substate. - For example, each integer of a door state describes in what phase the machine is in during parking. Substates are detailed in the documentation. - Feature: With the alarm codes, homing and probe alarms have been expanded with more codes to provide more exact feedback on what caused the alarm. - Feature: New hard limit check upon power-up or reset. If detected, a feedback message to check the limit switches sent immediately after the welcome message. - May be disabled in config.h. - OEM feature: Enable/disable `$RST=` individual commands based on desired behavior in config.h. - OEM feature: Configurable EEPROM wipe to prevent certain data from being deleted during firmware upgrade to a new settings version or `RST=*` command. - OEM feature: Enable/disable the `$I=` build info write string with external EEPROM write example sketch. - This prevents a user from altering the build info string in EEPROM. This requires the vendor to write the string to EEPROM via external means. An Arduino example sketch is provided to accomplish this. This would be useful for contain product data that is retrievable. - Tweak: All feedback has been drastically trimmed to free up flash space for the v1.0 release. - The `$` help message is just one string, listing available commands. - The `$$` settings printout no longer includes descriptions. Only the setting values. (Sorry it’s this or remove overrides!) - Grbl `error:` and `ALARM:` responses now only contain codes. No descriptions. All codes are explained in documentation. - Grbl’s old feedback style may be restored via a config.h, but keep in mind that it will likely not fit into the Arduino’s flash space. - Tweak: Grbl now forces a buffer sync or stop motion whenever a g-code command needs to update and write a value to EEPROM or changes the work coordinate offset. - This addresses two old issues in all prior Grbl versions. First, an EEPROM write requires interrupts to be disabled, including stepper and serial comm. Steps can be lost and data can be corrupted. Second, the work position may not be correlated to the actual machine position, since machine position is derived from the actual current execution state, while work position is based on the g-code parser offset state. They are usually not in sync and the parser state is several motions behind. This forced sync ensures work and machine positions are always correct. - This behavior can be disabled through a config.h option, but it’s not recommended to do so. - Tweak: To make status reports standardized, users can no longer change what is reported via status report mask, except for only toggling machine or work positions. - All other data fields are included in the report and can only be disabled through the config.h file. It’s not recommended to alter this, because GUIs will be expecting this data to be present and may not be compatible. - Tweak: Homing cycle and parking motion no longer report a negative line number in a status report. These will now not report a line number at all. - Tweak: New `[Restoring spindle]` message when restoring from a spindle stop override. Provides feedback what Grbl is doing while the spindle is powering up and a 4.0 second delay is enforced. - Tweak: Override values are reset to 100% upon M2/30. This behavior can be disabled in config.h - Tweak: The planner buffer size has been reduced from 18 to 16 to free up RAM for tracking and controlling overrides. - Tweak: TX buffer size has been increased from 64 to 90 bytes to improve status reporting and overall performance. - Tweak: Removed the MOTION CANCEL state. It was redundant and didn’t affect Grbl’s overall operation by doing so. - Tweak: Grbl’s serial buffer increased by +1 internally, such that 128 bytes means 128, not 127 due to the ring buffer implementation. Long overdue. - Tweak: Altered sys.alarm variable to be set by alarm codes, rather than bit flags. Simplified how it worked overall. - Tweak: Planner buffer and serial RX buffer usage has been combined in the status reports. - Tweak: Pin state reporting has been refactored to report only the pins “triggered” and nothing when not “triggered”. - Tweak: Current machine rate or speed is now included in every report. - Tweak: The work coordinate offset (WCO) and override states only need to be refreshed intermittently or reported when they change. The refresh rates may be altered for each in the config.h file with different idle and busy rates to lessen Grbl’s load during a job. - Tweak: For temporary compatibility to existing GUIs until they are updated, an option to revert back to the old style status reports is available in config.h, but not recommended for long term use. - Tweak: Removed old limit pin state reporting option from config.h in lieu of new status report that includes them. - Tweak: Updated the defaults.h file to include laser mode, altered status report mask, and fix an issue with a missing invert probe pin default. - Refactor: Changed how planner line data is generated and passed to the planner and onto the step generator. By making it a struct variable, this saved significant flash space. - Refactor: Major re-factoring of the planner to incorporate override values and allow for re-calculations fast enough to immediately take effect during operation. No small feat. - Refactor: Re-factored the step segment generator for re-computing new override states. - Refactor: Re-factored spindle_control.c to accommodate the spindle speed overrides and laser mode. - Refactor: Re-factored parts of the codebase for a new jogging mode. Still under development though and slated to be part of the official v1.0 release. Hang tight. - Refactor: Created functions for computing a unit vector and value limiting based on axis maximums to free up more flash. - Refactor: The spindle PWM is now set directly inside of the stepper ISR as it loads new step segments. - Refactor: Moved machine travel checks out of soft limits function into its own since jogging uses this too. - Refactor: Removed coolant_stop() and combined with coolant_set_state(). - Refactor: The serial RX ISR forks off extended ASCII values to quickly assess the new override realtime commands. - Refactor: Altered some names of the step control flags. - Refactor: Improved efficiency of the serial RX get buffer count function. - Refactor: Saved significant flash by removing and combining print functions. Namely the uint8 base10 and base2 functions. - Refactor: Moved the probe state check in the main stepper ISR to improve its efficiency. - Refactor: Single character printPgmStrings() went converted to direct serial_write() commands to save significant flash space. - Documentation: Detailed Markdown documents on error codes, alarm codes, messages, new real-time commands, new status reports, and how jogging works. More to come later and will be posted on the Wiki as well. - Documentation: CSV files for quick importing of Grbl error and alarm codes. - Bug Fix: Applied v0.9 master fixes to CoreXY homing. - Bug Fix: The print float function would cause Grbl to crash if a value was 1e6 or greater. Increased the buffer by 3 bytes to help prevent this in the future. - Bug Fix: Build info and startup string EEPROM restoring was not writing the checksum value. - Bug Fix: Corrected an issue with safety door restoring the proper spindle and coolant state. It worked before, but breaks with laser mode that can continually change spindle state per planner block. - Bug Fix: Move system position and probe position arrays out of the system_t struct. Ran into some compiling errors that were hard to track down as to why. Moving them out fixed it.

void write_global_settings(bool commit)
Re-factored system states and alarm management. Serial baud support greater than 57600. - Refactored system states to be more clear and concise. Alarm locks processes when position is unknown to indicate to user something has gone wrong. - Changed mc_alarm to mc_reset, which now manages the system reset function. Centralizes it. - Renamed '$X' kill homing lock to kill alarm lock. - Created an alarm error reporting method to clear up what is an alarm: message vs a status error: message. For GUIs mainly. Alarm codes are negative. Status codes are positive. - Serial baud support upto 115200. Previous baudrate calc was unstable for 57600 and above. - Alarm state locks out all g-code blocks, including startup scripts, but allows user to access settings and internal commands. For example, to disable hard limits, if they are problematic. - Hard limits do not respond in an alarm state. - Fixed a problem with the hard limit interrupt during the homing cycle. The interrupt register is still active during the homing cycle and still signal the interrupt to trigger when re-enabled. Instead, just disabled the register. - Homing rate adjusted. All axes move at homing seek rate, regardless of how many axes move at the same time. This is unlike how the stepper module does it as a point to point rate. - New config.h settings to disable the homing rate adjustment and the force homing upon powerup. - Reduced the number of startup lines back down to 2 from 3. This discourages users from placing motion block in there, which can be very dangerous. - Startup blocks now run only after an alarm-free reset or after a homing cycle. Does not run when $X kill is called. For satefy reasons

Lots of re-organization and cleaning-up. Some bug fixes. - Added a new source and header file called system. These files contain the system commands and variables, as well as all of the system headers and standard libraries Grbl uses. Centralizing some of the code. - Re-organized the include headers throughout the source code. - ENABLE_M7 define was missing from config.h. Now there. - SPINDLE_MAX_RPM and SPINDLE_MIN_RPM now defined in config.h. No uncommenting to prevent user issues. Minimum spindle RPM now provides the lower, near 0V, scale adjustment, i.e. some spindles can go really slow so why use up our 256 voltage bins for them? - Remove some persistent variables from coolant and spindle control. They were redundant. - Removed a VARIABLE_SPINDLE define in cpu_map.h that shouldn’t have been there. - Changed the DEFAULT_ARC_TOLERANCE to 0.002mm to improve arc tracing. Before we had issues with performance, no longer. - Fixed a bug with the hard limits and the software debounce feature enabled. The invert limit pin setting wasn’t honored. - Fixed a bug with the homing direction mask. Now is like it used to be. At least for now. - Re-organized main.c to serve as only as the reset/initialization routine. Makes things a little bit clearer in terms of execution procedures. - Re-organized protocol.c as the overall master control unit for execution procedures. Not quite there yet, but starting to make a little more sense in how things are run. - Removed updating of old settings records. So many new settings have been added that it’s not worth adding the code to migrate old user settings. - Tweaked spindle_control.c a bit and made it more clear and consistent with other parts of Grbl. - Tweaked the stepper disable bit code in stepper.c. Requires less flash memory.

Grbl v1.0e huge beta release. Overrides and new reporting. - Feature: Realtime feed, rapid, and spindle speed overrides. These alter the running machine state within tens of milliseconds! - Feed override: 100%, +/-10%, +/-1% commands with values 1-200% of programmed feed - Rapid override: 100%, 50%, 25% rapid rate commands - Spindle speed override: 100%, +/-10%, +/-1% commands with values 50-200% of programmed speed - Override values have configurable limits and increments in config.h. - Feature: Realtime toggle overrides for spindle stop, flood coolant, and optionally mist coolant - Spindle stop: Enables and disables spindle during a feed hold. Automatically restores last spindles state. - Flood and mist coolant: Immediately toggles coolant state until next toggle or g-code coolant command. - Feature: Jogging mode! Incremental and absolute modes supported. - Grbl accepts jogging-specific commands like $J=X100F50. An axis word and feed rate are required. G20/21 and G90/G91 commands are accepted. - Jog motions can be canceled at any time by a feed hold `!` command. The buffer is automatically flushed. (No resetting required). - Jog motions do not alter the g-code parser state so GUIs don’t have to track what they changed and correct it. - Feature: Laser mode setting. Allows Grbl to execute continuous motions with spindle speed and state changes. - Feature: Significantly improved status reports. Overhauled to cram in more meaningful data and still make it smaller on average. - All available data is now sent by default, but does not appear if it doesn’t change or is not active. - Machine position(MPos) or work position(WPos) is reported but not both at the same time. Instead, the work coordinate offsets (WCO)are sent intermittently whenever it changes or refreshes after 10-30 status reports. Position vectors are easily computed by WPos = MPos - WCO. - All data has changed in some way. Details of changes are in the markdown documents and wiki. - Feature: 16 new realtime commands to control overrides. All in extended-ASCII character space. - While they are not easily typeable and requires a GUI, they can’t be accidentally triggered by some latent character in the g-code program and have tons of room for expansion. - Feature: New substates for HOLD and SAFETY DOOR.

// Method to restore EEPROM-saved Grbl global settings back to defaults.
void settings_restore(uint8_t restore_flag) {
New EEPROM restore functions. - Tweaked the previous EEPROM restore implementation and added new functionality. - `$RST=$` restores the `$$` grbl settings back to firmware defaults, which are set when compiled. - `$RST=#` restores the `$#` parameters in EEPROM. At times it’s useful to clear these and start over, rather than manually writing each entry. -`$RST=*` wipe all of the data in EEPROM that Grbl uses and restores them to defaults. This includes `$$` settings, `$#` parameters, `$N` startup lines, and `$i` build info string. NOTE: This doesn’t write zeros throughout the EEPROM. It only writes where Grbl looks for data. For a complete wipe, please use the Arduino IDE’s EEPROM clear example. - Refactored the restore and wipe functions in settings.c to accommodate the new commands.

Grbl v1.0e huge beta release. Overrides and new reporting. - Feature: Realtime feed, rapid, and spindle speed overrides. These alter the running machine state within tens of milliseconds! - Feed override: 100%, +/-10%, +/-1% commands with values 1-200% of programmed feed - Rapid override: 100%, 50%, 25% rapid rate commands - Spindle speed override: 100%, +/-10%, +/-1% commands with values 50-200% of programmed speed - Override values have configurable limits and increments in config.h. - Feature: Realtime toggle overrides for spindle stop, flood coolant, and optionally mist coolant - Spindle stop: Enables and disables spindle during a feed hold. Automatically restores last spindles state. - Flood and mist coolant: Immediately toggles coolant state until next toggle or g-code coolant command. - Feature: Jogging mode! Incremental and absolute modes supported. - Grbl accepts jogging-specific commands like $J=X100F50. An axis word and feed rate are required. G20/21 and G90/G91 commands are accepted. - Jog motions can be canceled at any time by a feed hold `!` command. The buffer is automatically flushed. (No resetting required). - Jog motions do not alter the g-code parser state so GUIs don’t have to track what they changed and correct it. - Feature: Laser mode setting. Allows Grbl to execute continuous motions with spindle speed and state changes. - Feature: Significantly improved status reports. Overhauled to cram in more meaningful data and still make it smaller on average. - All available data is now sent by default, but does not appear if it doesn’t change or is not active. - Machine position(MPos) or work position(WPos) is reported but not both at the same time. Instead, the work coordinate offsets (WCO)are sent intermittently whenever it changes or refreshes after 10-30 status reports. Position vectors are easily computed by WPos = MPos - WCO. - All data has changed in some way. Details of changes are in the markdown documents and wiki. - Feature: 16 new realtime commands to control overrides. All in extended-ASCII character space. - While they are not easily typeable and requires a GUI, they can’t be accidentally triggered by some latent character in the g-code program and have tons of room for expansion. - Feature: New substates for HOLD and SAFETY DOOR. A `:x` is appended to the state, where `x` is an integer and indicates a substate. - For example, each integer of a door state describes in what phase the machine is in during parking. Substates are detailed in the documentation. - Feature: With the alarm codes, homing and probe alarms have been expanded with more codes to provide more exact feedback on what caused the alarm. - Feature: New hard limit check upon power-up or reset. If detected, a feedback message to check the limit switches sent immediately after the welcome message. - May be disabled in config.h. - OEM feature: Enable/disable `$RST=` individual commands based on desired behavior in config.h. - OEM feature: Configurable EEPROM wipe to prevent certain data from being deleted during firmware upgrade to a new settings version or `RST=*` command. - OEM feature: Enable/disable the `$I=` build info write string with external EEPROM write example sketch. - This prevents a user from altering the build info string in EEPROM. This requires the vendor to write the string to EEPROM via external means. An Arduino example sketch is provided to accomplish this. This would be useful for contain product data that is retrievable. - Tweak: All feedback has been drastically trimmed to free up flash space for the v1.0 release. - The `$` help message is just one string, listing available commands. - The `$$` settings printout no longer includes descriptions. Only the setting values. (Sorry it’s this or remove overrides!) - Grbl `error:` and `ALARM:` responses now only contain codes. No descriptions. All codes are explained in documentation. - Grbl’s old feedback style may be restored via a config.h, but keep in mind that it will likely not fit into the Arduino’s flash space. - Tweak: Grbl now forces a buffer sync or stop motion whenever a g-code command needs to update and write a value to EEPROM or changes the work coordinate offset. - This addresses two old issues in all prior Grbl versions. First, an EEPROM write requires interrupts to be disabled, including stepper and serial comm. Steps can be lost and data can be corrupted. Second, the work position may not be correlated to the actual machine position, since machine position is derived from the actual current execution state, while work position is based on the g-code parser offset state. They are usually not in sync and the parser state is several motions behind. This forced sync ensures work and machine positions are always correct. - This behavior can be disabled through a config.h option, but it’s not recommended to do so. - Tweak: To make status reports standardized, users can no longer change what is reported via status report mask, except for only toggling machine or work positions. - All other data fields are included in the report and can only be disabled through the config.h file. It’s not recommended to alter this, because GUIs will be expecting this data to be present and may not be compatible. - Tweak: Homing cycle and parking motion no longer report a negative line number in a status report. These will now not report a line number at all. - Tweak: New `[Restoring spindle]` message when restoring from a spindle stop override. Provides feedback what Grbl is doing while the spindle is powering up and a 4.0 second delay is enforced. - Tweak: Override values are reset to 100% upon M2/30. This behavior can be disabled in config.h - Tweak: The planner buffer size has been reduced from 18 to 16 to free up RAM for tracking and controlling overrides. - Tweak: TX buffer size has been increased from 64 to 90 bytes to improve status reporting and overall performance. - Tweak: Removed the MOTION CANCEL state. It was redundant and didn’t affect Grbl’s overall operation by doing so. - Tweak: Grbl’s serial buffer increased by +1 internally, such that 128 bytes means 128, not 127 due to the ring buffer implementation. Long overdue. - Tweak: Altered sys.alarm variable to be set by alarm codes, rather than bit flags. Simplified how it worked overall. - Tweak: Planner buffer and serial RX buffer usage has been combined in the status reports. - Tweak: Pin state reporting has been refactored to report only the pins “triggered” and nothing when not “triggered”. - Tweak: Current machine rate or speed is now included in every report. - Tweak: The work coordinate offset (WCO) and override states only need to be refreshed intermittently or reported when they change. The refresh rates may be altered for each in the config.h file with different idle and busy rates to lessen Grbl’s load during a job. - Tweak: For temporary compatibility to existing GUIs until they are updated, an option to revert back to the old style status reports is available in config.h, but not recommended for long term use. - Tweak: Removed old limit pin state reporting option from config.h in lieu of new status report that includes them. - Tweak: Updated the defaults.h file to include laser mode, altered status report mask, and fix an issue with a missing invert probe pin default. - Refactor: Changed how planner line data is generated and passed to the planner and onto the step generator. By making it a struct variable, this saved significant flash space. - Refactor: Major re-factoring of the planner to incorporate override values and allow for re-calculations fast enough to immediately take effect during operation. No small feat. - Refactor: Re-factored the step segment generator for re-computing new override states. - Refactor: Re-factored spindle_control.c to accommodate the spindle speed overrides and laser mode. - Refactor: Re-factored parts of the codebase for a new jogging mode. Still under development though and slated to be part of the official v1.0 release. Hang tight. - Refactor: Created functions for computing a unit vector and value limiting based on axis maximums to free up more flash. - Refactor: The spindle PWM is now set directly inside of the stepper ISR as it loads new step segments. - Refactor: Moved machine travel checks out of soft limits function into its own since jogging uses this too. - Refactor: Removed coolant_stop() and combined with coolant_set_state(). - Refactor: The serial RX ISR forks off extended ASCII values to quickly assess the new override realtime commands. - Refactor: Altered some names of the step control flags. - Refactor: Improved efficiency of the serial RX get buffer count function. - Refactor: Saved significant flash by removing and combining print functions. Namely the uint8 base10 and base2 functions. - Refactor: Moved the probe state check in the main stepper ISR to improve its efficiency. - Refactor: Single character printPgmStrings() went converted to direct serial_write() commands to save significant flash space. - Documentation: Detailed Markdown documents on error codes, alarm codes, messages, new real-time commands, new status reports, and how jogging works.

Grbl v1.0e huge beta release. Overrides and new reporting. - Feature: Realtime feed, rapid, and spindle speed overrides. These alter the running machine state within tens of milliseconds! - Feed override: 100%, +/-10%, +/-1% commands with values 1-200% of programmed feed - Rapid override: 100%, 50%, 25% rapid rate commands - Spindle speed override: 100%, +/-10%, +/-1% commands with values 50-200% of programmed speed - Override values have configurable limits and increments in config.h. - Feature: Realtime toggle overrides for spindle stop, flood coolant, and optionally mist coolant - Spindle stop: Enables and disables spindle during a feed hold. Automatically restores last spindles state. - Flood and mist coolant: Immediately toggles coolant state until next toggle or g-code coolant command. - Feature: Jogging mode! Incremental and absolute modes supported. - Grbl accepts jogging-specific commands like $J=X100F50. An axis word and feed rate are required. G20/21 and G90/G91 commands are accepted. - Jog motions can be canceled at any time by a feed hold `!` command. The buffer is automatically flushed. (No resetting required). - Jog motions do not alter the g-code parser state so GUIs don’t have to track what they changed and correct it. - Feature: Laser mode setting. Allows Grbl to execute continuous motions with spindle speed and state changes. - Feature: Significantly improved status reports. Overhauled to cram in more meaningful data and still make it smaller on average. - All available data is now sent by default, but does not appear if it doesn’t change or is not active. - Machine position(MPos) or work position(WPos) is reported but not both at the same time. Instead, the work coordinate offsets (WCO)are sent intermittently whenever it changes or refreshes after 10-30 status reports. Position vectors are easily computed by WPos = MPos - WCO. - All data has changed in some way. Details of changes are in the markdown documents and wiki. - Feature: 16 new realtime commands to control overrides. All in extended-ASCII character space. - While they are not easily typeable and requires a GUI, they can’t be accidentally triggered by some latent character in the g-code program and have tons of room for expansion. - Feature: New substates for HOLD and SAFETY DOOR. A `:x` is appended to the state, where `x` is an integer and indicates a substate. - For example, each integer of a door state describes in what phase the machine is in during parking. Substates are detailed in the documentation. - Feature: With the alarm codes, homing and probe alarms have been expanded with more codes to provide more exact feedback on what caused the alarm. - Feature: New hard limit check upon power-up or reset. If detected, a feedback message to check the limit switches sent immediately after the welcome message. - May be disabled in config.h. - OEM feature: Enable/disable `$RST=` individual commands based on desired behavior in config.h. - OEM feature: Configurable EEPROM wipe to prevent certain data from being deleted during firmware upgrade to a new settings version or `RST=*` command. - OEM feature: Enable/disable the `$I=` build info write string with external EEPROM write example sketch. - This prevents a user from altering the build info string in EEPROM. This requires the vendor to write the string to EEPROM via external means. An Arduino example sketch is provided to accomplish this. This would be useful for contain product data that is retrievable. - Tweak: All feedback has been drastically trimmed to free up flash space for the v1.0 release. - The `$` help message is just one string, listing available commands. - The `$$` settings printout no longer includes descriptions. Only the setting values. (Sorry it’s this or remove overrides!) - Grbl `error:` and `ALARM:` responses now only contain codes. No descriptions. All codes are explained in documentation. - Grbl’s old feedback style may be restored via a config.h, but keep in mind that it will likely not fit into the Arduino’s flash space. - Tweak: Grbl now forces a buffer sync or stop motion whenever a g-code command needs to update and write a value to EEPROM or changes the work coordinate offset. - This addresses two old issues in all prior Grbl versions. First, an EEPROM write requires interrupts to be disabled, including stepper and serial comm. Steps can be lost and data can be corrupted. Second, the work position may not be correlated to the actual machine position, since machine position is derived from the actual current execution state, while work position is based on the g-code parser offset state. They are usually not in sync and the parser state is several motions behind. This forced sync ensures work and machine positions are always correct. - This behavior can be disabled through a config.h option, but it’s not recommended to do so. - Tweak: To make status reports standardized, users can no longer change what is reported via status report mask, except for only toggling machine or work positions. - All other data fields are included in the report and can only be disabled through the config.h file. It’s not recommended to alter this, because GUIs will be expecting this data to be present and may not be compatible. - Tweak: Homing cycle and parking motion no longer report a negative line number in a status report. These will now not report a line number at all. - Tweak: New `[Restoring spindle]` message when restoring from a spindle stop override. Provides feedback what Grbl is doing while the spindle is powering up and a 4.0 second delay is enforced. - Tweak: Override values are reset to 100% upon M2/30. This behavior can be disabled in config.h - Tweak: The planner buffer size has been reduced from 18 to 16 to free up RAM for tracking and controlling overrides. - Tweak: TX buffer size has been increased from 64 to 90 bytes to improve status reporting and overall performance. - Tweak: Removed the MOTION CANCEL state. It was redundant and didn’t affect Grbl’s overall operation by doing so. - Tweak: Grbl’s serial buffer increased by +1 internally, such that 128 bytes means 128, not 127 due to the ring buffer implementation. Long overdue. - Tweak: Altered sys.alarm variable to be set by alarm codes, rather than bit flags. Simplified how it worked overall. - Tweak: Planner buffer and serial RX buffer usage has been combined in the status reports. - Tweak: Pin state reporting has been refactored to report only the pins “triggered” and nothing when not “triggered”. - Tweak: Current machine rate or speed is now included in every report. - Tweak: The work coordinate offset (WCO) and override states only need to be refreshed intermittently or reported when they change. The refresh rates may be altered for each in the config.h file with different idle and busy rates to lessen Grbl’s load during a job. - Tweak: For temporary compatibility to existing GUIs until they are updated, an option to revert back to the old style status reports is available in config.h, but not recommended for long term use. - Tweak: Removed old limit pin state reporting option from config.h in lieu of new status report that includes them. - Tweak: Updated the defaults.h file to include laser mode, altered status report mask, and fix an issue with a missing invert probe pin default. - Refactor: Changed how planner line data is generated and passed to the planner and onto the step generator. By making it a struct variable, this saved significant flash space. - Refactor: Major re-factoring of the planner to incorporate override values and allow for re-calculations fast enough to immediately take effect during operation. No small feat. - Refactor: Re-factored the step segment generator for re-computing new override states. - Refactor: Re-factored spindle_control.c to accommodate the spindle speed overrides and laser mode. - Refactor: Re-factored parts of the codebase for a new jogging mode. Still under development though and slated to be part of the official v1.0 release. Hang tight. - Refactor: Created functions for computing a unit vector and value limiting based on axis maximums to free up more flash. - Refactor: The spindle PWM is now set directly inside of the stepper ISR as it loads new step segments. - Refactor: Moved machine travel checks out of soft limits function into its own since jogging uses this too. - Refactor: Removed coolant_stop() and combined with coolant_set_state(). - Refactor: The serial RX ISR forks off extended ASCII values to quickly assess the new override realtime commands. - Refactor: Altered some names of the step control flags. - Refactor: Improved efficiency of the serial RX get buffer count function. - Refactor: Saved significant flash by removing and combining print functions. Namely the uint8 base10 and base2 functions. - Refactor: Moved the probe state check in the main stepper ISR to improve its efficiency. - Refactor: Single character printPgmStrings() went converted to direct serial_write() commands to save significant flash space. - Documentation: Detailed Markdown documents on error codes, alarm codes, messages, new real-time commands, new status reports, and how jogging works.

New EEPROM restore functions. - Tweaked the previous EEPROM restore implementation and added new functionality. - `$RST=$` restores the `$$` grbl settings back to firmware defaults, which are set when compiled. - `$RST=#` restores the `$#` parameters in EEPROM. At times it’s useful to clear these and start over, rather than manually writing each entry. -`$RST=*` wipe all of the data in EEPROM that Grbl uses and restores them to defaults. This includes `$$` settings, `$#` parameters, `$N` startup lines, and `$i` build info string. NOTE: This doesn’t write zeros throughout the EEPROM. It only writes where Grbl looks for data. For a complete wipe, please use the Arduino IDE’s EEPROM clear example. - Refactored the restore and wipe functions in settings.c to accommodate the new commands.

if (restore_flag & SETTINGS_RESTORE_PARAMETERS) {
Grbl v1.0e huge beta release. Overrides and new reporting. - Feature: Realtime feed, rapid, and spindle speed overrides. These alter the running machine state within tens of milliseconds! - Feed override: 100%, +/-10%, +/-1% commands with values 1-200% of programmed feed - Rapid override: 100%, 50%, 25% rapid rate commands - Spindle speed override: 100%, +/-10%, +/-1% commands with values 50-200% of programmed speed - Override values have configurable limits and increments in config.h. - Feature: Realtime toggle overrides for spindle stop, flood coolant, and optionally mist coolant - Spindle stop: Enables and disables spindle during a feed hold. Automatically restores last spindles state. - Flood and mist coolant: Immediately toggles coolant state until next toggle or g-code coolant command. - Feature: Jogging mode! Incremental and absolute modes supported. - Grbl accepts jogging-specific commands like $J=X100F50. An axis word and feed rate are required. G20/21 and G90/G91 commands are accepted. - Jog motions can be canceled at any time by a feed hold `!` command. The buffer is automatically flushed. (No resetting required). - Jog motions do not alter the g-code parser state so GUIs don’t have to track what they changed and correct it. - Feature: Laser mode setting. Allows Grbl to execute continuous motions with spindle speed and state changes. - Feature: Significantly improved status reports. Overhauled to cram in more meaningful data and still make it smaller on average. - All available data is now sent by default, but does not appear if it doesn’t change or is not active. - Machine position(MPos) or work position(WPos) is reported but not both at the same time. Instead, the work coordinate offsets (WCO)are sent intermittently whenever it changes or refreshes after 10-30 status reports. Position vectors are easily computed by WPos = MPos - WCO. - All data has changed in some way. Details of changes are in the markdown documents and wiki. - Feature: 16 new realtime commands to control overrides. All in extended-ASCII character space. - While they are not easily typeable and requires a GUI, they can’t be accidentally triggered by some latent character in the g-code program and have tons of room for expansion. - Feature: New substates for HOLD and SAFETY DOOR. A `:x` is appended to the state, where `x` is an integer and indicates a substate. - For example, each integer of a door state describes in what phase the machine is in during parking. Substates are detailed in the documentation. - Feature: With the alarm codes, homing and probe alarms have been expanded with more codes to provide more exact feedback on what caused the alarm. - Feature: New hard limit check upon power-up or reset. If detected, a feedback message to check the limit switches sent immediately after the welcome message. - May be disabled in config.h. - OEM feature: Enable/disable `$RST=` individual commands based on desired behavior in config.h. - OEM feature: Configurable EEPROM wipe to prevent certain data from being deleted during firmware upgrade to a new settings version or `RST=*` command. - OEM feature: Enable/disable the `$I=` build info write string with external EEPROM write example sketch. - This prevents a user from altering the build info string in EEPROM. This requires the vendor to write the string to EEPROM via external means. An Arduino example sketch is provided to accomplish this. This would be useful for contain product data that is retrievable. - Tweak: All feedback has been drastically trimmed to free up flash space for the v1.0 release. - The `$` help message is just one string, listing available commands. - The `$$` settings printout no longer includes descriptions. Only the setting values. (Sorry it’s this or remove overrides!) - Grbl `error:` and `ALARM:` responses now only contain codes. No descriptions. All codes are explained in documentation. - Grbl’s old feedback style may be restored via a config.h, but keep in mind that it will likely not fit into the Arduino’s flash space. - Tweak: Grbl now forces a buffer sync or stop motion whenever a g-code command needs to update and write a value to EEPROM or changes the work coordinate offset. - This addresses two old issues in all prior Grbl versions. First, an EEPROM write requires interrupts to be disabled, including stepper and serial comm. Steps can be lost and data can be corrupted. Second, the work position may not be correlated to the actual machine position, since machine position is derived from the actual current execution state, while work position is based on the g-code parser offset state. They are usually not in sync and the parser state is several motions behind. This forced sync ensures work and machine positions are always correct. - This behavior can be disabled through a config.h option, but it’s not recommended to do so. - Tweak: To make status reports standardized, users can no longer change what is reported via status report mask, except for only toggling machine or work positions. - All other data fields are included in the report and can only be disabled through the config.h file. It’s not recommended to alter this, because GUIs will be expecting this data to be present and may not be compatible. - Tweak: Homing cycle and parking motion no longer report a negative line number in a status report. These will now not report a line number at all. - Tweak: New `[Restoring spindle]` message when restoring from a spindle stop override. Provides feedback what Grbl is doing while the spindle is powering up and a 4.0 second delay is enforced. - Tweak: Override values are reset to 100% upon M2/30. This behavior can be disabled in config.h - Tweak: The planner buffer size has been reduced from 18 to 16 to free up RAM for tracking and controlling overrides. - Tweak: TX buffer size has been increased from 64 to 90 bytes to improve status reporting and overall performance. - Tweak: Removed the MOTION CANCEL state. It was redundant and didn’t affect Grbl’s overall operation by doing so. - Tweak: Grbl’s serial buffer increased by +1 internally, such that 128 bytes means 128, not 127 due to the ring buffer implementation. Long overdue. - Tweak: Altered sys.alarm variable to be set by alarm codes, rather than bit flags. Simplified how it worked overall. - Tweak: Planner buffer and serial RX buffer usage has been combined in the status reports. - Tweak: Pin state reporting has been refactored to report only the pins “triggered” and nothing when not “triggered”. - Tweak: Current machine rate or speed is now included in every report. - Tweak: The work coordinate offset (WCO) and override states only need to be refreshed intermittently or reported when they change. The refresh rates may be altered for each in the config.h file with different idle and busy rates to lessen Grbl’s load during a job. - Tweak: For temporary compatibility to existing GUIs until they are updated, an option to revert back to the old style status reports is available in config.h, but not recommended for long term use. - Tweak: Removed old limit pin state reporting option from config.h in lieu of new status report that includes them. - Tweak: Updated the defaults.h file to include laser mode, altered status report mask, and fix an issue with a missing invert probe pin default. - Refactor: Changed how planner line data is generated and passed to the planner and onto the step generator. By making it a struct variable, this saved significant flash space. - Refactor: Major re-factoring of the planner to incorporate override values and allow for re-calculations fast enough to immediately take effect during operation. No small feat. - Refactor: Re-factored the step segment generator for re-computing new override states. - Refactor: Re-factored spindle_control.c to accommodate the spindle speed overrides and laser mode. - Refactor: Re-factored parts of the codebase for a new jogging mode. Still under development though and slated to be part of the official v1.0 release. Hang tight. - Refactor: Created functions for computing a unit vector and value limiting based on axis maximums to free up more flash. - Refactor: The spindle PWM is now set directly inside of the stepper ISR as it loads new step segments. - Refactor: Moved machine travel checks out of soft limits function into its own since jogging uses this too. - Refactor: Removed coolant_stop() and combined with coolant_set_state(). - Refactor: The serial RX ISR forks off extended ASCII values to quickly assess the new override realtime commands. - Refactor: Altered some names of the step control flags. - Refactor: Improved efficiency of the serial RX get buffer count function. - Refactor: Saved significant flash by removing and combining print functions. Namely the uint8 base10 and base2 functions. - Refactor: Moved the probe state check in the main stepper ISR to improve its efficiency. - Refactor: Single character printPgmStrings() went converted to direct serial_write() commands to save significant flash space. - Documentation: Detailed Markdown documents on error codes, alarm codes, messages, new real-time commands, new status reports, and how jogging works. More to come later and will be posted on the Wiki as well. - Documentation: CSV files for quick importing of Grbl error and alarm codes. - Bug Fix: Applied v0.9 master fixes to CoreXY homing. - Bug Fix: The print float function would cause Grbl to crash if a value was 1e6 or greater. Increased the buffer by 3 bytes to help prevent this in the future. - Bug Fix: Build info and startup string EEPROM restoring was not writing the checksum value. - Bug Fix: Corrected an issue with safety door restoring the proper spindle and coolant state. It worked before, but breaks with laser mode that can continually change spindle state per planner block. - Bug Fix: Move system position and probe position arrays out of the system_t struct. Ran into some compiling errors that were hard to track down as to why. Moving them out fixed it.

Final minor updates for master release. - Updated ShapeOko2 defaults based on machine testing of the basic model provided by Inventables. (or close to it.) Should be pretty conservative but much faster than before. For example, X and Y axes are set at (10x) faster at 5000mm/min. It can run much faster than this, but this seems like a safe speed for everyone. - Updated README for master release. - Added some new settings methods for clearing the EEPROM when changing versions. Needs some more work, but it should ok for master release. Should work on it more for the next version.

Re-factored system states and alarm management. Serial baud support greater than 57600. - Refactored system states to be more clear and concise. Alarm locks processes when position is unknown to indicate to user something has gone wrong. - Changed mc_alarm to mc_reset, which now manages the system reset function. Centralizes it. - Renamed '$X' kill homing lock to kill alarm lock. - Created an alarm error reporting method to clear up what is an alarm: message vs a status error: message. For GUIs mainly. Alarm codes are negative. Status codes are positive. - Serial baud support upto 115200. Previous baudrate calc was unstable for 57600 and above. - Alarm state locks out all g-code blocks, including startup scripts, but allows user to access settings and internal commands. For example, to disable hard limits, if they are problematic. - Hard limits do not respond in an alarm state. - Fixed a problem with the hard limit interrupt during the homing cycle. The interrupt register is still active during the homing cycle and still signal the interrupt to trigger when re-enabled. Instead, just disabled the register. - Homing rate adjusted. All axes move at homing seek rate, regardless of how many axes move at the same time. This is unlike how the stepper module does it as a point to point rate. - New config.h settings to disable the homing rate adjustment and the force homing upon powerup. - Reduced the number of startup lines back down to 2 from 3. This discourages users from placing motion block in there, which can be very dangerous. - Startup blocks now run only after an alarm-free reset or after a homing cycle. Does not run when $X kill is called. For satefy reasons

Probing cycle and view build info bug fixes. - Probing cycle would drop into a QUEUED state, if multiple G38.2 are sent. It would not honor the auto cycle start flags. To fix, the auto cycle start state is saved at the beginning of the probing cycle and restored at the end, since the feed hold it uses to stop a triggered probe will disable the auto start flag. For now it’s a patch, rather than a permanent fix. - protocol_buffer_synchronize() also has a failure case. Auto cycle start does not get executed when the system is waiting in here, so if it’s in a QUEUED state already, it won’t resume. Patched here, but not fully resolved. - Fixed a problem with the “view build info” command. The EEPROM write would do weird things and corrupt the EEPROM. Not sure exactly what caused it, but it’s likely a compiler problem with an improperly defined EEPROM address. It didn’t have enough room to store a full string. To fix, the build info EEPROM range was increased and the max number of STARTUP_BLOCKS was reduced to 2 from 3. - Lastly, when a $I view build info is used for the first time, it would normally show an EEPROM read error, since it wasn’t cleared or wasn’t therein the first place. It will now not show that error. A patch rather than a permanent fix again.

Lots of re-organization and cleaning-up. Some bug fixes. - Added a new source and header file called system. These files contain the system commands and variables, as well as all of the system headers and standard libraries Grbl uses. Centralizing some of the code. - Re-organized the include headers throughout the source code. - ENABLE_M7 define was missing from config.h. Now there. - SPINDLE_MAX_RPM and SPINDLE_MIN_RPM now defined in config.h. No uncommenting to prevent user issues. Minimum spindle RPM now provides the lower, near 0V, scale adjustment, i.e. some spindles can go really slow so why use up our 256 voltage bins for them? - Remove some persistent variables from coolant and spindle control. They were redundant. - Removed a VARIABLE_SPINDLE define in cpu_map.h that shouldn’t have been there. - Changed the DEFAULT_ARC_TOLERANCE to 0.002mm to improve arc tracing. Before we had issues with performance, no longer. - Fixed a bug with the hard limits and the software debounce feature enabled. The invert limit pin setting wasn’t honored. - Fixed a bug with the homing direction mask. Now is like it used to be. At least for now. - Re-organized main.c to serve as only as the reset/initialization routine. Makes things a little bit clearer in terms of execution procedures. - Re-organized protocol.c as the overall master control unit for execution procedures. Not quite there yet, but starting to make a little more sense in how things are run. - Removed updating of old settings records. So many new settings have been added that it’s not worth adding the code to migrate old user settings. - Tweaked spindle_control.c a bit and made it more clear and consistent with other parts of Grbl. - Tweaked the stepper disable bit code in stepper.c. Requires less flash memory.

// Reset with default zero vector
Grbl v1.0e huge beta release. Overrides and new reporting. - Feature: Realtime feed, rapid, and spindle speed overrides. These alter the running machine state within tens of milliseconds! - Feed override: 100%, +/-10%, +/-1% commands with values 1-200% of programmed feed - Rapid override: 100%, 50%, 25% rapid rate commands - Spindle speed override: 100%, +/-10%, +/-1% commands with values 50-200% of programmed speed - Override values have configurable limits and increments in config.h. - Feature: Realtime toggle overrides for spindle stop, flood coolant, and optionally mist coolant - Spindle stop: Enables and disables spindle during a feed hold. Automatically restores last spindles state. - Flood and mist coolant: Immediately toggles coolant state until next toggle or g-code coolant command. - Feature: Jogging mode! Incremental and absolute modes supported. - Grbl accepts jogging-specific commands like $J=X100F50. An axis word and feed rate are required. G20/21 and G90/G91 commands are accepted. - Jog motions can be canceled at any time by a feed hold `!` command. The buffer is automatically flushed. (No resetting required). - Jog motions do not alter the g-code parser state so GUIs don’t have to track what they changed and correct it. - Feature: Laser mode setting. Allows Grbl to execute continuous motions with spindle speed and state changes. - Feature: Significantly improved status reports. Overhauled to cram in more meaningful data and still make it smaller on average. - All available data is now sent by default, but does not appear if it doesn’t change or is not active. - Machine position(MPos) or work position(WPos) is reported but not both at the same time. Instead, the work coordinate offsets (WCO)are sent intermittently whenever it changes or refreshes after 10-30 status reports. Position vectors are easily computed by WPos = MPos - WCO. - All data has changed in some way. Details of changes are in the markdown documents and wiki. - Feature: 16 new realtime commands to control overrides. All in extended-ASCII character space. - While they are not easily typeable and requires a GUI, they can’t be accidentally triggered by some latent character in the g-code program and have tons of room for expansion. - Feature: New substates for HOLD and SAFETY DOOR. A `:x` is appended to the state, where `x` is an integer and indicates a substate. - For example, each integer of a door state describes in what phase the machine is in during parking. Substates are detailed in the documentation. - Feature: With the alarm codes, homing and probe alarms have been expanded with more codes to provide more exact feedback on what caused the alarm. - Feature: New hard limit check upon power-up or reset. If detected, a feedback message to check the limit switches sent immediately after the welcome message. - May be disabled in config.h. - OEM feature: Enable/disable `$RST=` individual commands based on desired behavior in config.h. - OEM feature: Configurable EEPROM wipe to prevent certain data from being deleted during firmware upgrade to a new settings version or `RST=*` command. - OEM feature: Enable/disable the `$I=` build info write string with external EEPROM write example sketch. - This prevents a user from altering the build info string in EEPROM. This requires the vendor to write the string to EEPROM via external means. An Arduino example sketch is provided to accomplish this. This would be useful for contain product data that is retrievable. - Tweak: All feedback has been drastically trimmed to free up flash space for the v1.0 release. - The `$` help message is just one string, listing available commands. - The `$$` settings printout no longer includes descriptions. Only the setting values. (Sorry it’s this or remove overrides!) - Grbl `error:` and `ALARM:` responses now only contain codes. No descriptions. All codes are explained in documentation. - Grbl’s old feedback style may be restored via a config.h, but keep in mind that it will likely not fit into the Arduino’s flash space. - Tweak: Grbl now forces a buffer sync or stop motion whenever a g-code command needs to update and write a value to EEPROM or changes the work coordinate offset. - This addresses two old issues in all prior Grbl versions. First, an EEPROM write requires interrupts to be disabled, including stepper and serial comm. Steps can be lost and data can be corrupted. Second, the work position may not be correlated to the actual machine position, since machine position is derived from the actual current execution state, while work position is based on the g-code parser offset state. They are usually not in sync and the parser state is several motions behind. This forced sync ensures work and machine positions are always correct. - This behavior can be disabled through a config.h option, but it’s not recommended to do so. - Tweak: To make status reports standardized, users can no longer change what is reported via status report mask, except for only toggling machine or work positions. - All other data fields are included in the report and can only be disabled through the config.h file. It’s not recommended to alter this, because GUIs will be expecting this data to be present and may not be compatible. - Tweak: Homing cycle and parking motion no longer report a negative line number in a status report. These will now not report a line number at all. - Tweak: New `[Restoring spindle]` message when restoring from a spindle stop override. Provides feedback what Grbl is doing while the spindle is powering up and a 4.0 second delay is enforced. - Tweak: Override values are reset to 100% upon M2/30. This behavior can be disabled in config.h - Tweak: The planner buffer size has been reduced from 18 to 16 to free up RAM for tracking and controlling overrides. - Tweak: TX buffer size has been increased from 64 to 90 bytes to improve status reporting and overall performance. - Tweak: Removed the MOTION CANCEL state. It was redundant and didn’t affect Grbl’s overall operation by doing so. - Tweak: Grbl’s serial buffer increased by +1 internally, such that 128 bytes means 128, not 127 due to the ring buffer implementation. Long overdue. - Tweak: Altered sys.alarm variable to be set by alarm codes, rather than bit flags. Simplified how it worked overall. - Tweak: Planner buffer and serial RX buffer usage has been combined in the status reports. - Tweak: Pin state reporting has been refactored to report only the pins “triggered” and nothing when not “triggered”. - Tweak: Current machine rate or speed is now included in every report. - Tweak: The work coordinate offset (WCO) and override states only need to be refreshed intermittently or reported when they change. The refresh rates may be altered for each in the config.h file with different idle and busy rates to lessen Grbl’s load during a job. - Tweak: For temporary compatibility to existing GUIs until they are updated, an option to revert back to the old style status reports is available in config.h, but not recommended for long term use. - Tweak: Removed old limit pin state reporting option from config.h in lieu of new status report that includes them. - Tweak: Updated the defaults.h file to include laser mode, altered status report mask, and fix an issue with a missing invert probe pin default. - Refactor: Changed how planner line data is generated and passed to the planner and onto the step generator. By making it a struct variable, this saved significant flash space. - Refactor: Major re-factoring of the planner to incorporate override values and allow for re-calculations fast enough to immediately take effect during operation. No small feat. - Refactor: Re-factored the step segment generator for re-computing new override states. - Refactor: Re-factored spindle_control.c to accommodate the spindle speed overrides and laser mode. - Refactor: Re-factored parts of the codebase for a new jogging mode. Still under development though and slated to be part of the official v1.0 release. Hang tight. - Refactor: Created functions for computing a unit vector and value limiting based on axis maximums to free up more flash. - Refactor: The spindle PWM is now set directly inside of the stepper ISR as it loads new step segments. - Refactor: Moved machine travel checks out of soft limits function into its own since jogging uses this too. - Refactor: Removed coolant_stop() and combined with coolant_set_state(). - Refactor: The serial RX ISR forks off extended ASCII values to quickly assess the new override realtime commands. - Refactor: Altered some names of the step control flags. - Refactor: Improved efficiency of the serial RX get buffer count function. - Refactor: Saved significant flash by removing and combining print functions. Namely the uint8 base10 and base2 functions. - Refactor: Moved the probe state check in the main stepper ISR to improve its efficiency. - Refactor: Single character printPgmStrings() went converted to direct serial_write() commands to save significant flash space. - Documentation: Detailed Markdown documents on error codes, alarm codes, messages, new real-time commands, new status reports, and how jogging works. More to come later and will be posted on the Wiki as well. - Documentation: CSV files for quick importing of Grbl error and alarm codes. - Bug Fix: Applied v0.9 master fixes to CoreXY homing. - Bug Fix: The print float function would cause Grbl to crash if a value was 1e6 or greater. Increased the buffer by 3 bytes to help prevent this in the future. - Bug Fix: Build info and startup string EEPROM restoring was not writing the checksum value. - Bug Fix: Corrected an issue with safety door restoring the proper spindle and coolant state. It worked before, but breaks with laser mode that can continually change spindle state per planner block. - Bug Fix: Move system position and probe position arrays out of the system_t struct. Ran into some compiling errors that were hard to track down as to why. Moving them out fixed it.

Re-factored system states and alarm management. Serial baud support greater than 57600. - Refactored system states to be more clear and concise. Alarm locks processes when position is unknown to indicate to user something has gone wrong. - Changed mc_alarm to mc_reset, which now manages the system reset function. Centralizes it. - Renamed '$X' kill homing lock to kill alarm lock. - Created an alarm error reporting method to clear up what is an alarm: message vs a status error: message. For GUIs mainly. Alarm codes are negative. Status codes are positive. - Serial baud support upto 115200. Previous baudrate calc was unstable for 57600 and above. - Alarm state locks out all g-code blocks, including startup scripts, but allows user to access settings and internal commands. For example, to disable hard limits, if they are problematic. - Hard limits do not respond in an alarm state. - Fixed a problem with the hard limit interrupt during the homing cycle. The interrupt register is still active during the homing cycle and still signal the interrupt to trigger when re-enabled. Instead, just disabled the register. - Homing rate adjusted. All axes move at homing seek rate, regardless of how many axes move at the same time. This is unlike how the stepper module does it as a point to point rate. - New config.h settings to disable the homing rate adjustment and the force homing upon powerup. - Reduced the number of startup lines back down to 2 from 3. This discourages users from placing motion block in there, which can be very dangerous. - Startup blocks now run only after an alarm-free reset or after a homing cycle. Does not run when $X kill is called. For satefy reasons

Probing cycle and view build info bug fixes. - Probing cycle would drop into a QUEUED state, if multiple G38.2 are sent. It would not honor the auto cycle start flags. To fix, the auto cycle start state is saved at the beginning of the probing cycle and restored at the end, since the feed hold it uses to stop a triggered probe will disable the auto start flag. For now it’s a patch, rather than a permanent fix. - protocol_buffer_synchronize() also has a failure case. Auto cycle start does not get executed when the system is waiting in here, so if it’s in a QUEUED state already, it won’t resume. Patched here, but not fully resolved. - Fixed a problem with the “view build info” command. The EEPROM write would do weird things and corrupt the EEPROM. Not sure exactly what caused it, but it’s likely a compiler problem with an improperly defined EEPROM address. It didn’t have enough room to store a full string. To fix, the build info EEPROM range was increased and the max number of STARTUP_BLOCKS was reduced to 2 from 3. - Lastly, when a $I view build info is used for the first time, it would normally show an EEPROM read error, since it wasn’t cleared or wasn’t therein the first place. It will now not show that error. A patch rather than a permanent fix again.

Grbl v1.0e huge beta release. Overrides and new reporting. - Feature: Realtime feed, rapid, and spindle speed overrides. These alter the running machine state within tens of milliseconds! - Feed override: 100%, +/-10%, +/-1% commands with values 1-200% of programmed feed - Rapid override: 100%, 50%, 25% rapid rate commands - Spindle speed override: 100%, +/-10%, +/-1% commands with values 50-200% of programmed speed - Override values have configurable limits and increments in config.h. - Feature: Realtime toggle overrides for spindle stop, flood coolant, and optionally mist coolant - Spindle stop: Enables and disables spindle during a feed hold. Automatically restores last spindles state. - Flood and mist coolant: Immediately toggles coolant state until next toggle or g-code coolant command. - Feature: Jogging mode! Incremental and absolute modes supported. - Grbl accepts jogging-specific commands like $J=X100F50. An axis word and feed rate are required. G20/21 and G90/G91 commands are accepted. - Jog motions can be canceled at any time by a feed hold `!` command. The buffer is automatically flushed. (No resetting required). - Jog motions do not alter the g-code parser state so GUIs don’t have to track what they changed and correct it. - Feature: Laser mode setting. Allows Grbl to execute continuous motions with spindle speed and state changes. - Feature: Significantly improved status reports. Overhauled to cram in more meaningful data and still make it smaller on average. - All available data is now sent by default, but does not appear if it doesn’t change or is not active. - Machine position(MPos) or work position(WPos) is reported but not both at the same time. Instead, the work coordinate offsets (WCO)are sent intermittently whenever it changes or refreshes after 10-30 status reports. Position vectors are easily computed by WPos = MPos - WCO. - All data has changed in some way. Details of changes are in the markdown documents and wiki. - Feature: 16 new realtime commands to control overrides. All in extended-ASCII character space. - While they are not easily typeable and requires a GUI, they can’t be accidentally triggered by some latent character in the g-code program and have tons of room for expansion. - Feature: New substates for HOLD and SAFETY DOOR. A `:x` is appended to the state, where `x` is an integer and indicates a substate. - For example, each integer of a door state describes in what phase the machine is in during parking. Substates are detailed in the documentation. - Feature: With the alarm codes, homing and probe alarms have been expanded with more codes to provide more exact feedback on what caused the alarm. - Feature: New hard limit check upon power-up or reset. If detected, a feedback message to check the limit switches sent immediately after the welcome message. - May be disabled in config.h. - OEM feature: Enable/disable `$RST=` individual commands based on desired behavior in config.h. - OEM feature: Configurable EEPROM wipe to prevent certain data from being deleted during firmware upgrade to a new settings version or `RST=*` command. - OEM feature: Enable/disable the `$I=` build info write string with external EEPROM write example sketch. - This prevents a user from altering the build info string in EEPROM. This requires the vendor to write the string to EEPROM via external means. An Arduino example sketch is provided to accomplish this. This would be useful for contain product data that is retrievable. - Tweak: All feedback has been drastically trimmed to free up flash space for the v1.0 release. - The `$` help message is just one string, listing available commands. - The `$$` settings printout no longer includes descriptions. Only the setting values. (Sorry it’s this or remove overrides!) - Grbl `error:` and `ALARM:` responses now only contain codes. No descriptions. All codes are explained in documentation. - Grbl’s old feedback style may be restored via a config.h, but keep in mind that it will likely not fit into the Arduino’s flash space. - Tweak: Grbl now forces a buffer sync or stop motion whenever a g-code command needs to update and write a value to EEPROM or changes the work coordinate offset. - This addresses two old issues in all prior Grbl versions.

Lots of re-organization and cleaning-up. Some bug fixes. - Added a new source and header file called system. These files contain the system commands and variables, as well as all of the system headers and standard libraries Grbl uses. Centralizing some of the code. - Re-organized the include headers throughout the source code. - ENABLE_M7 define was missing from config.h. Now there. - SPINDLE_MAX_RPM and SPINDLE_MIN_RPM now defined in config.h. No uncommenting to prevent user issues. Minimum spindle RPM now provides the lower, near 0V, scale adjustment, i.e. some spindles can go really slow so why use up our 256 voltage bins for them? - Remove some persistent variables from coolant and spindle control. They were redundant. - Removed a VARIABLE_SPINDLE define in cpu_map.h that shouldn’t have been there. - Changed the DEFAULT_ARC_TOLERANCE to 0.002mm to improve arc tracing. Before we had issues with performance, no longer. - Fixed a bug with the hard limits and the software debounce feature enabled. The invert limit pin setting wasn’t honored. - Fixed a bug with the homing direction mask. Now is like it used to be. At least for now. - Re-organized main.c to serve as only as the reset/initialization routine. Makes things a little bit clearer in terms of execution procedures. - Re-organized protocol.c as the overall master control unit for execution procedures. Not quite there yet, but starting to make a little more sense in how things are run. - Removed updating of old settings records. So many new settings have been added that it’s not worth adding the code to migrate old user settings. - Tweaked spindle_control.c a bit and made it more clear and consistent with other parts of Grbl. - Tweaked the stepper disable bit code in stepper.c. Requires less flash memory.

More to come later and will be posted on the Wiki as well. - Documentation: CSV files for quick importing of Grbl error and alarm codes. - Bug Fix: Applied v0.9 master fixes to CoreXY homing. - Bug Fix: The print float function would cause Grbl to crash if a value was 1e6 or greater. Increased the buffer by 3 bytes to help prevent this in the future. - Bug Fix: Build info and startup string EEPROM restoring was not writing the checksum value. - Bug Fix: Corrected an issue with safety door restoring the proper spindle and coolant state. It worked before, but breaks with laser mode that can continually change spindle state per planner block. - Bug Fix: Move system position and probe position arrays out of the system_t struct. Ran into some compiling errors that were hard to track down as to why. Moving them out fixed it.

return(false);
Re-factored system states and alarm management. Serial baud support greater than 57600. - Refactored system states to be more clear and concise. Alarm locks processes when position is unknown to indicate to user something has gone wrong. - Changed mc_alarm to mc_reset, which now manages the system reset function. Centralizes it. - Renamed '$X' kill homing lock to kill alarm lock. - Created an alarm error reporting method to clear up what is an alarm: message vs a status error: message. For GUIs mainly. Alarm codes are negative. Status codes are positive. - Serial baud support upto 115200. Previous baudrate calc was unstable for 57600 and above. - Alarm state locks out all g-code blocks, including startup scripts, but allows user to access settings and internal commands. For example, to disable hard limits, if they are problematic. - Hard limits do not respond in an alarm state. - Fixed a problem with the hard limit interrupt during the homing cycle. The interrupt register is still active during the homing cycle and still signal the interrupt to trigger when re-enabled. Instead, just disabled the register. - Homing rate adjusted. All axes move at homing seek rate, regardless of how many axes move at the same time. This is unlike how the stepper module does it as a point to point rate. - New config.h settings to disable the homing rate adjustment and the force homing upon powerup. - Reduced the number of startup lines back down to 2 from 3. This discourages users from placing motion block in there, which can be very dangerous. - Startup blocks now run only after an alarm-free reset or after a homing cycle. Does not run when $X kill is called. For satefy reasons

Settings refactoring. Bug fixes. Misc new features. This is likely the last major change to the v0.9 code base before push to master. Only two minor things remain on the agenda (CoreXY support, force clear EEPROM, and an extremely low federate bug). - NEW! Grbl is now compile-able and may be flashed directly through the Arduino IDE. Only minor changes were required for this compatibility. See the Wiki to learn how to do it. - New status reporting mask to turn on and off what Grbl sends back. This includes machine coordinates, work coordinates, serial RX buffer usage, and planner buffer usage. Expandable to more information on user request, but that’s it for now. - Settings have been completely renumbered to allow for future new settings to be installed without having to constantly reshuffle and renumber all of the settings every time. - All settings masks have been standardized to mean bit 0 = X, bit 1 = Y, and bit 2 = Z, to reduce confusion on how they work. The invert masks used by the internal Grbl system were updated to accommodate this change as well. - New invert probe pin setting, which does what it sounds like. - Fixed a probing cycle bug, where it would freeze intermittently, and removed some redundant code. - Homing may now be set to the origin wherever the limit switches are. Traditionally machine coordinates should always be in negative space, but when limit switches on are on the opposite side, the machine coordinate would be set to -max_travel for the axis. Now you can always make it [0,0,0] via a compile-time option in config.h. (Soft limits routine was updated to account for this as well.) - Probe coordinate message immediately after a probing cycle may now be turned off via a compile-time option in config.h. By default the probing location is always reported. - Reduced the N_ARC_CORRECTION default value to reflect the changes in how circles are generated by an arc tolerance, rather than a fixed arc segment setting. - Increased the incoming line buffer limit from 70 to 80 characters. Had some extra memory space to invest into this. - Fixed a bug where tool number T was not being tracked and reported correctly. - Added a print free memory function for debugging purposes. Not used otherwise. - Realtime rate report should now work during feed holds, but it hasn’t been tested yet. - Updated the streaming scripts with MIT-license and added the simple streaming to the main stream.py script to allow for settings to be sent. - Some minor code refactoring to improve flash efficiency. Reduced the flash by several hundred KB, which was re-invested in some of these new features.

Grbl v1.0e huge beta release. Overrides and new reporting. - Feature: Realtime feed, rapid, and spindle speed overrides. These alter the running machine state within tens of milliseconds! - Feed override: 100%, +/-10%, +/-1% commands with values 1-200% of programmed feed - Rapid override: 100%, 50%, 25% rapid rate commands - Spindle speed override: 100%, +/-10%, +/-1% commands with values 50-200% of programmed speed - Override values have configurable limits and increments in config.h. - Feature: Realtime toggle overrides for spindle stop, flood coolant, and optionally mist coolant - Spindle stop: Enables and disables spindle during a feed hold. Automatically restores last spindles state. - Flood and mist coolant: Immediately toggles coolant state until next toggle or g-code coolant command. - Feature: Jogging mode! Incremental and absolute modes supported. - Grbl accepts jogging-specific commands like $J=X100F50. An axis word and feed rate are required. G20/21 and G90/G91 commands are accepted. - Jog motions can be canceled at any time by a feed hold `!` command. The buffer is automatically flushed. (No resetting required). - Jog motions do not alter the g-code parser state so GUIs don’t have to track what they changed and correct it. - Feature: Laser mode setting. Allows Grbl to execute continuous motions with spindle speed and state changes. - Feature: Significantly improved status reports. Overhauled to cram in more meaningful data and still make it smaller on average. - All available data is now sent by default, but does not appear if it doesn’t change or is not active. - Machine position(MPos) or work position(WPos) is reported but not both at the same time. Instead, the work coordinate offsets (WCO)are sent intermittently whenever it changes or refreshes after 10-30 status reports. Position vectors are easily computed by WPos = MPos - WCO. - All data has changed in some way. Details of changes are in the markdown documents and wiki. - Feature: 16 new realtime commands to control overrides. All in extended-ASCII character space. - While they are not easily typeable and requires a GUI, they can’t be accidentally triggered by some latent character in the g-code program and have tons of room for expansion. - Feature: New substates for HOLD and SAFETY DOOR. A `:x` is appended to the state, where `x` is an integer and indicates a substate. - For example, each integer of a door state describes in what phase the machine is in during parking. Substates are detailed in the documentation. - Feature: With the alarm codes, homing and probe alarms have been expanded with more codes to provide more exact feedback on what caused the alarm. - Feature: New hard limit check upon power-up or reset. If detected, a feedback message to check the limit switches sent immediately after the welcome message. - May be disabled in config.h. - OEM feature: Enable/disable `$RST=` individual commands based on desired behavior in config.h. - OEM feature: Configurable EEPROM wipe to prevent certain data from being deleted during firmware upgrade to a new settings version or `RST=*` command. - OEM feature: Enable/disable the `$I=` build info write string with external EEPROM write example sketch. - This prevents a user from altering the build info string in EEPROM. This requires the vendor to write the string to EEPROM via external means. An Arduino example sketch is provided to accomplish this. This would be useful for contain product data that is retrievable. - Tweak: All feedback has been drastically trimmed to free up flash space for the v1.0 release. - The `$` help message is just one string, listing available commands. - The `$$` settings printout no longer includes descriptions. Only the setting values. (Sorry it’s this or remove overrides!) - Grbl `error:` and `ALARM:` responses now only contain codes. No descriptions. All codes are explained in documentation. - Grbl’s old feedback style may be restored via a config.h, but keep in mind that it will likely not fit into the Arduino’s flash space. - Tweak: Grbl now forces a buffer sync or stop motion whenever a g-code command needs to update and write a value to EEPROM or changes the work coordinate offset. - This addresses two old issues in all prior Grbl versions. First, an EEPROM write requires interrupts to be disabled, including stepper and serial comm. Steps can be lost and data can be corrupted. Second, the work position may not be correlated to the actual machine position, since machine position is derived from the actual current execution state, while work position is based on the g-code parser offset state. They are usually not in sync and the parser state is several motions behind. This forced sync ensures work and machine positions are always correct. - This behavior can be disabled through a config.h option, but it’s not recommended to do so. - Tweak: To make status reports standardized, users can no longer change what is reported via status report mask, except for only toggling machine or work positions. - All other data fields are included in the report and can only be disabled through the config.h file. It’s not recommended to alter this, because GUIs will be expecting this data to be present and may not be compatible. - Tweak: Homing cycle and parking motion no longer report a negative line number in a status report. These will now not report a line number at all. - Tweak: New `[Restoring spindle]` message when restoring from a spindle stop override. Provides feedback what Grbl is doing while the spindle is powering up and a 4.0 second delay is enforced. - Tweak: Override values are reset to 100% upon M2/30. This behavior can be disabled in config.h - Tweak: The planner buffer size has been reduced from 18 to 16 to free up RAM for tracking and controlling overrides. - Tweak: TX buffer size has been increased from 64 to 90 bytes to improve status reporting and overall performance. - Tweak: Removed the MOTION CANCEL state. It was redundant and didn’t affect Grbl’s overall operation by doing so. - Tweak: Grbl’s serial buffer increased by +1 internally, such that 128 bytes means 128, not 127 due to the ring buffer implementation. Long overdue. - Tweak: Altered sys.alarm variable to be set by alarm codes, rather than bit flags. Simplified how it worked overall. - Tweak: Planner buffer and serial RX buffer usage has been combined in the status reports. - Tweak: Pin state reporting has been refactored to report only the pins “triggered” and nothing when not “triggered”. - Tweak: Current machine rate or speed is now included in every report. - Tweak: The work coordinate offset (WCO) and override states only need to be refreshed intermittently or reported when they change. The refresh rates may be altered for each in the config.h file with different idle and busy rates to lessen Grbl’s load during a job. - Tweak: For temporary compatibility to existing GUIs until they are updated, an option to revert back to the old style status reports is available in config.h, but not recommended for long term use. - Tweak: Removed old limit pin state reporting option from config.h in lieu of new status report that includes them. - Tweak: Updated the defaults.h file to include laser mode, altered status report mask, and fix an issue with a missing invert probe pin default. - Refactor: Changed how planner line data is generated and passed to the planner and onto the step generator. By making it a struct variable, this saved significant flash space. - Refactor: Major re-factoring of the planner to incorporate override values and allow for re-calculations fast enough to immediately take effect during operation. No small feat. - Refactor: Re-factored the step segment generator for re-computing new override states. - Refactor: Re-factored spindle_control.c to accommodate the spindle speed overrides and laser mode. - Refactor: Re-factored parts of the codebase for a new jogging mode. Still under development though and slated to be part of the official v1.0 release. Hang tight. - Refactor: Created functions for computing a unit vector and value limiting based on axis maximums to free up more flash. - Refactor: The spindle PWM is now set directly inside of the stepper ISR as it loads new step segments. - Refactor: Moved machine travel checks out of soft limits function into its own since jogging uses this too. - Refactor: Removed coolant_stop() and combined with coolant_set_state(). - Refactor: The serial RX ISR forks off extended ASCII values to quickly assess the new override realtime commands. - Refactor: Altered some names of the step control flags. - Refactor: Improved efficiency of the serial RX get buffer count function. - Refactor: Saved significant flash by removing and combining print functions. Namely the uint8 base10 and base2 functions. - Refactor: Moved the probe state check in the main stepper ISR to improve its efficiency. - Refactor: Single character printPgmStrings() went converted to direct serial_write() commands to save significant flash space. - Documentation: Detailed Markdown documents on error codes, alarm codes, messages, new real-time commands, new status reports, and how jogging works. More to come later and will be posted on the Wiki as well. - Documentation: CSV files for quick importing of Grbl error and alarm codes. - Bug Fix: Applied v0.9 master fixes to CoreXY homing. - Bug Fix: The print float function would cause Grbl to crash if a value was 1e6 or greater. Increased the buffer by 3 bytes to help prevent this in the future. - Bug Fix: Build info and startup string EEPROM restoring was not writing the checksum value. - Bug Fix: Corrected an issue with safety door restoring the proper spindle and coolant state.

Ran into some compiling errors that were hard to track down as to why. Moving them out fixed it.

Allows Grbl to execute continuous motions with spindle speed and state changes. - Feature: Significantly improved status reports. Overhauled to cram in more meaningful data and still make it smaller on average. - All available data is now sent by default, but does not appear if it doesn’t change or is not active. - Machine position(MPos) or work position(WPos) is reported but not both at the same time. Instead, the work coordinate offsets (WCO)are sent intermittently whenever it changes or refreshes after 10-30 status reports. Position vectors are easily computed by WPos = MPos - WCO. - All data has changed in some way. Details of changes are in the markdown documents and wiki. - Feature: 16 new realtime commands to control overrides. All in extended-ASCII character space. - While they are not easily typeable and requires a GUI, they can’t be accidentally triggered by some latent character in the g-code program and have tons of room for expansion. - Feature: New substates for HOLD and SAFETY DOOR. A `:x` is appended to the state, where `x` is an integer and indicates a substate. - For example, each integer of a door state describes in what phase the machine is in during parking. Substates are detailed in the documentation. - Feature: With the alarm codes, homing and probe alarms have been expanded with more codes to provide more exact feedback on what caused the alarm. - Feature: New hard limit check upon power-up or reset. If detected, a feedback message to check the limit switches sent immediately after the welcome message. - May be disabled in config.h. - OEM feature: Enable/disable `$RST=` individual commands based on desired behavior in config.h. - OEM feature: Configurable EEPROM wipe to prevent certain data from being deleted during firmware upgrade to a new settings version or `RST=*` command. - OEM feature: Enable/disable the `$I=` build info write string with external EEPROM write example sketch. - This prevents a user from altering the build info string in EEPROM. This requires the vendor to write the string to EEPROM via external means. An Arduino example sketch is provided to accomplish this. This would be useful for contain product data that is retrievable. - Tweak: All feedback has been drastically trimmed to free up flash space for the v1.0 release. - The `$` help message is just one string, listing available commands. - The `$$` settings printout no longer includes descriptions. Only the setting values. (Sorry it’s this or remove overrides!) - Grbl `error:` and `ALARM:` responses now only contain codes. No descriptions. All codes are explained in documentation. - Grbl’s old feedback style may be restored via a config.h, but keep in mind that it will likely not fit into the Arduino’s flash space. - Tweak: Grbl now forces a buffer sync or stop motion whenever a g-code command needs to update and write a value to EEPROM or changes the work coordinate offset. - This addresses two old issues in all prior Grbl versions. First, an EEPROM write requires interrupts to be disabled, including stepper and serial comm. Steps can be lost and data can be corrupted. Second, the work position may not be correlated to the actual machine position, since machine position is derived from the actual current execution state, while work position is based on the g-code parser offset state. They are usually not in sync and the parser state is several motions behind. This forced sync ensures work and machine positions are always correct. - This behavior can be disabled through a config.h option, but it’s not recommended to do so. - Tweak: To make status reports standardized, users can no longer change what is reported via status report mask, except for only toggling machine or work positions. - All other data fields are included in the report and can only be disabled through the config.h file. It’s not recommended to alter this, because GUIs will be expecting this data to be present and may not be compatible. - Tweak: Homing cycle and parking motion no longer report a negative line number in a status report. These will now not report a line number at all. - Tweak: New `[Restoring spindle]` message when restoring from a spindle stop override. Provides feedback what Grbl is doing while the spindle is powering up and a 4.0 second delay is enforced. - Tweak: Override values are reset to 100% upon M2/30. This behavior can be disabled in config.h - Tweak: The planner buffer size has been reduced from 18 to 16 to free up RAM for tracking and controlling overrides. - Tweak: TX buffer size has been increased from 64 to 90 bytes to improve status reporting and overall performance. - Tweak: Removed the MOTION CANCEL state. It was redundant and didn’t affect Grbl’s overall operation by doing so. - Tweak: Grbl’s serial buffer increased by +1 internally, such that 128 bytes means 128, not 127 due to the ring buffer implementation. Long overdue. - Tweak: Altered sys.alarm variable to be set by alarm codes, rather than bit flags. Simplified how it worked overall. - Tweak: Planner buffer and serial RX buffer usage has been combined in the status reports. - Tweak: Pin state reporting has been refactored to report only the pins “triggered” and nothing when not “triggered”. - Tweak: Current machine rate or speed is now included in every report. - Tweak: The work coordinate offset (WCO) and override states only need to be refreshed intermittently or reported when they change. The refresh rates may be altered for each in the config.h file with different idle and busy rates to lessen Grbl’s load during a job. - Tweak: For temporary compatibility to existing GUIs until they are updated, an option to revert back to the old style status reports is available in config.h, but not recommended for long term use. - Tweak: Removed old limit pin state reporting option from config.h in lieu of new status report that includes them. - Tweak: Updated the defaults.h file to include laser mode, altered status report mask, and fix an issue with a missing invert probe pin default. - Refactor: Changed how planner line data is generated and passed to the planner and onto the step generator. By making it a struct variable, this saved significant flash space. - Refactor: Major re-factoring of the planner to incorporate override values and allow for re-calculations fast enough to immediately take effect during operation. No small feat. - Refactor: Re-factored the step segment generator for re-computing new override states. - Refactor: Re-factored spindle_control.c to accommodate the spindle speed overrides and laser mode. - Refactor: Re-factored parts of the codebase for a new jogging mode. Still under development though and slated to be part of the official v1.0 release. Hang tight. - Refactor: Created functions for computing a unit vector and value limiting based on axis maximums to free up more flash. - Refactor: The spindle PWM is now set directly inside of the stepper ISR as it loads new step segments. - Refactor: Moved machine travel checks out of soft limits function into its own since jogging uses this too. - Refactor: Removed coolant_stop() and combined with coolant_set_state(). - Refactor: The serial RX ISR forks off extended ASCII values to quickly assess the new override realtime commands. - Refactor: Altered some names of the step control flags. - Refactor: Improved efficiency of the serial RX get buffer count function. - Refactor: Saved significant flash by removing and combining print functions. Namely the uint8 base10 and base2 functions. - Refactor: Moved the probe state check in the main stepper ISR to improve its efficiency. - Refactor: Single character printPgmStrings() went converted to direct serial_write() commands to save significant flash space. - Documentation: Detailed Markdown documents on error codes, alarm codes, messages, new real-time commands, new status reports, and how jogging works. More to come later and will be posted on the Wiki as well. - Documentation: CSV files for quick importing of Grbl error and alarm codes. - Bug Fix: Applied v0.9 master fixes to CoreXY homing. - Bug Fix: The print float function would cause Grbl to crash if a value was 1e6 or greater. Increased the buffer by 3 bytes to help prevent this in the future. - Bug Fix: Build info and startup string EEPROM restoring was not writing the checksum value. - Bug Fix: Corrected an issue with safety door restoring the proper spindle and coolant state. It worked before, but breaks with laser mode that can continually change spindle state per planner block. - Bug Fix: Move system position and probe position arrays out of the system_t struct. Ran into some compiling errors that were hard to track down as to why. Moving them out fixed it.

Settings refactoring. Bug fixes. Misc new features. This is likely the last major change to the v0.9 code base before push to master. Only two minor things remain on the agenda (CoreXY support, force clear EEPROM, and an extremely low federate bug). - NEW! Grbl is now compile-able and may be flashed directly through the Arduino IDE. Only minor changes were required for this compatibility. See the Wiki to learn how to do it. - New status reporting mask to turn on and off what Grbl sends back. This includes machine coordinates, work coordinates, serial RX buffer usage, and planner buffer usage. Expandable to more information on user request, but that’s it for now. - Settings have been completely renumbered to allow for future new settings to be installed without having to constantly reshuffle and renumber all of the settings every time. - All settings masks have been standardized to mean bit 0 = X, bit 1 = Y, and bit 2 = Z, to reduce confusion on how they work. The invert masks used by the internal Grbl system were updated to accommodate this change as well. - New invert probe pin setting, which does what it sounds like. - Fixed a probing cycle bug, where it would freeze intermittently, and removed some redundant code. - Homing may now be set to the origin wherever the limit switches are. Traditionally machine coordinates should always be in negative space, but when limit switches on are on the opposite side, the machine coordinate would be set to -max_travel for the axis. Now you can always make it [0,0,0] via a compile-time option in config.h. (Soft limits routine was updated to account for this as well.) - Probe coordinate message immediately after a probing cycle may now be turned off via a compile-time option in config.h. By default the probing location is always reported. - Reduced the N_ARC_CORRECTION default value to reflect the changes in how circles are generated by an arc tolerance, rather than a fixed arc segment setting. - Increased the incoming line buffer limit from 70 to 80 characters. Had some extra memory space to invest into this. - Fixed a bug where tool number T was not being tracked and reported correctly. - Added a print free memory function for debugging purposes. Not used otherwise. - Realtime rate report should now work during feed holds, but it hasn’t been tested yet. - Updated the streaming scripts with MIT-license and added the simple streaming to the main stream.py script to allow for settings to be sent. - Some minor code refactoring to improve flash efficiency. Reduced the flash by several hundred KB, which was re-invested in some of these new features.

case 2:
settings.step_invert_mask = int_value;
Minor bug fixes. - Bug fix for step and direction invert masks not immediately being in effect. Now regenerates the masks when a user changes this setting. - Bug fix for probing cycle. G-code standard mandates that there is an error if the probe is already triggered when the cycle is commanded. However, Grbl may have motions to pull off a previous probing cycle in queue and can falsely lead to errors. To fix this, the triggered check is performed within the probing cycle itself, right after the planner buffer is synced. If there is an error, it will now alarm out as a probe fail.

Now you can always make it [0,0,0] via a compile-time option in config.h. (Soft limits routine was updated to account for this as well.) - Probe coordinate message immediately after a probing cycle may now be turned off via a compile-time option in config.h. By default the probing location is always reported. - Reduced the N_ARC_CORRECTION default value to reflect the changes in how circles are generated by an arc tolerance, rather than a fixed arc segment setting. - Increased the incoming line buffer limit from 70 to 80 characters. Had some extra memory space to invest into this. - Fixed a bug where tool number T was not being tracked and reported correctly. - Added a print free memory function for debugging purposes. Not used otherwise. - Realtime rate report should now work during feed holds, but it hasn’t been tested yet. - Updated the streaming scripts with MIT-license and added the simple streaming to the main stream.py script to allow for settings to be sent. - Some minor code refactoring to improve flash efficiency. Reduced the flash by several hundred KB, which was re-invested in some of these new features.

Grbl v1.0e huge beta release. Overrides and new reporting. - Feature: Realtime feed, rapid, and spindle speed overrides. These alter the running machine state within tens of milliseconds! - Feed override: 100%, +/-10%, +/-1% commands with values 1-200% of programmed feed - Rapid override: 100%, 50%, 25% rapid rate commands - Spindle speed override: 100%, +/-10%, +/-1% commands with values 50-200% of programmed speed - Override values have configurable limits and increments in config.h. - Feature: Realtime toggle overrides for spindle stop, flood coolant, and optionally mist coolant - Spindle stop: Enables and disables spindle during a feed hold. Automatically restores last spindles state. - Flood and mist coolant: Immediately toggles coolant state until next toggle or g-code coolant command. - Feature: Jogging mode! Incremental and absolute modes supported. - Grbl accepts jogging-specific commands like $J=X100F50. An axis word and feed rate are required. G20/21 and G90/G91 commands are accepted. - Jog motions can be canceled at any time by a feed hold `!` command. The buffer is automatically flushed. (No resetting required). - Jog motions do not alter the g-code parser state so GUIs don’t have to track what they changed and correct it. - Feature: Laser mode setting. Allows Grbl to execute continuous motions with spindle speed and state changes. - Feature: Significantly improved status reports. Overhauled to cram in more meaningful data and still make it smaller on average. - All available data is now sent by default, but does not appear if it doesn’t change or is not active. - Machine position(MPos) or work position(WPos) is reported but not both at the same time. Instead, the work coordinate offsets (WCO)are sent intermittently whenever it changes or refreshes after 10-30 status reports. Position vectors are easily computed by WPos = MPos - WCO. - All data has changed in some way. Details of changes are in the markdown documents and wiki. - Feature: 16 new realtime commands to control overrides. All in extended-ASCII character space. - While they are not easily typeable and requires a GUI, they can’t be accidentally triggered by some latent character in the g-code program and have tons of room for expansion. - Feature: New substates for HOLD and SAFETY DOOR. A `:x` is appended to the state, where `x` is an integer and indicates a substate. - For example, each integer of a door state describes in what phase the machine is in during parking. Substates are detailed in the documentation. - Feature: With the alarm codes, homing and probe alarms have been expanded with more codes to provide more exact feedback on what caused the alarm. - Feature: New hard limit check upon power-up or reset. If detected, a feedback message to check the limit switches sent immediately after the welcome message. - May be disabled in config.h. - OEM feature: Enable/disable `$RST=` individual commands based on desired behavior in config.h. - OEM feature: Configurable EEPROM wipe to prevent certain data from being deleted during firmware upgrade to a new settings version or `RST=*` command. - OEM feature: Enable/disable the `$I=` build info write string with external EEPROM write example sketch. - This prevents a user from altering the build info string in EEPROM. This requires the vendor to write the string to EEPROM via external means. An Arduino example sketch is provided to accomplish this. This would be useful for contain product data that is retrievable. - Tweak: All feedback has been drastically trimmed to free up flash space for the v1.0 release. - The `$` help message is just one string, listing available commands. - The `$$` settings printout no longer includes descriptions. Only the setting values. (Sorry it’s this or remove overrides!) - Grbl `error:` and `ALARM:` responses now only contain codes. No descriptions. All codes are explained in documentation. - Grbl’s old feedback style may be restored via a config.h, but keep in mind that it will likely not fit into the Arduino’s flash space. - Tweak: Grbl now forces a buffer sync or stop motion whenever a g-code command needs to update and write a value to EEPROM or changes the work coordinate offset. - This addresses two old issues in all prior Grbl versions. First, an EEPROM write requires interrupts to be disabled, including stepper and serial comm. Steps can be lost and data can be corrupted. Second, the work position may not be correlated to the actual machine position, since machine position is derived from the actual current execution state, while work position is based on the g-code parser offset state. They are usually not in sync and the parser state is several motions behind. This forced sync ensures work and machine positions are always correct. - This behavior can be disabled through a config.h option, but it’s not recommended to do so. - Tweak: To make status reports standardized, users can no longer change what is reported via status report mask, except for only toggling machine or work positions. - All other data fields are included in the report and can only be disabled through the config.h file. It’s not recommended to alter this, because GUIs will be expecting this data to be present and may not be compatible. - Tweak: Homing cycle and parking motion no longer report a negative line number in a status report. These will now not report a line number at all. - Tweak: New `[Restoring spindle]` message when restoring from a spindle stop override. Provides feedback what Grbl is doing while the spindle is powering up and a 4.0 second delay is enforced. - Tweak: Override values are reset to 100% upon M2/30. This behavior can be disabled in config.h - Tweak: The planner buffer size has been reduced from 18 to 16 to free up RAM for tracking and controlling overrides. - Tweak: TX buffer size has been increased from 64 to 90 bytes to improve status reporting and overall performance. - Tweak: Removed the MOTION CANCEL state. It was redundant and didn’t affect Grbl’s overall operation by doing so. - Tweak: Grbl’s serial buffer increased by +1 internally, such that 128 bytes means 128, not 127 due to the ring buffer implementation. Long overdue. - Tweak: Altered sys.alarm variable to be set by alarm codes, rather than bit flags. Simplified how it worked overall. - Tweak: Planner buffer and serial RX buffer usage has been combined in the status reports. - Tweak: Pin state reporting has been refactored to report only the pins “triggered” and nothing when not “triggered”. - Tweak: Current machine rate or speed is now included in every report. - Tweak: The work coordinate offset (WCO) and override states only need to be refreshed intermittently or reported when they change. The refresh rates may be altered for each in the config.h file with different idle and busy rates to lessen Grbl’s load during a job. - Tweak: For temporary compatibility to existing GUIs until they are updated, an option to revert back to the old style status reports is available in config.h, but not recommended for long term use. - Tweak: Removed old limit pin state reporting option from config.h in lieu of new status report that includes them. - Tweak: Updated the defaults.h file to include laser mode, altered status report mask, and fix an issue with a missing invert probe pin default. - Refactor: Changed how planner line data is generated and passed to the planner and onto the step generator. By making it a struct variable, this saved significant flash space. - Refactor: Major re-factoring of the planner to incorporate override values and allow for re-calculations fast enough to immediately take effect during operation. No small feat. - Refactor: Re-factored the step segment generator for re-computing new override states. - Refactor: Re-factored spindle_control.c to accommodate the spindle speed overrides and laser mode. - Refactor: Re-factored parts of the codebase for a new jogging mode. Still under development though and slated to be part of the official v1.0 release. Hang tight. - Refactor: Created functions for computing a unit vector and value limiting based on axis maximums to free up more flash. - Refactor: The spindle PWM is now set directly inside of the stepper ISR as it loads new step segments. - Refactor: Moved machine travel checks out of soft limits function into its own since jogging uses this too. - Refactor: Removed coolant_stop() and combined with coolant_set_state(). - Refactor: The serial RX ISR forks off extended ASCII values to quickly assess the new override realtime commands. - Refactor: Altered some names of the step control flags. - Refactor: Improved efficiency of the serial RX get buffer count function. - Refactor: Saved significant flash by removing and combining print functions. Namely the uint8 base10 and base2 functions. - Refactor: Moved the probe state check in the main stepper ISR to improve its efficiency. - Refactor: Single character printPgmStrings() went converted to direct serial_write() commands to save significant flash space. - Documentation: Detailed Markdown documents on error codes, alarm codes, messages, new real-time commands, new status reports, and how jogging works. More to come later and will be posted on the Wiki as well. - Documentation: CSV files for quick importing of Grbl error and alarm codes. - Bug Fix: Applied v0.9 master fixes to CoreXY homing. - Bug Fix: The print float function would cause Grbl to crash if a value was 1e6 or greater. Increased the buffer by 3 bytes to help prevent this in the future. - Bug Fix: Build info and startup string EEPROM restoring was not writing the checksum value. - Bug Fix: Corrected an issue with safety door restoring the proper spindle and coolant state. It worked before, but breaks with laser mode that can continually change spindle state per planner block. - Bug Fix: Move system position and probe position arrays out of the system_t struct. Ran into some compiling errors that were hard to track down as to why. Moving them out fixed it.

Settings refactoring. Bug fixes. Misc new features. This is likely the last major change to the v0.9 code base before push to master. Only two minor things remain on the agenda (CoreXY support, force clear EEPROM, and an extremely low federate bug). - NEW! Grbl is now compile-able and may be flashed directly through the Arduino IDE. Only minor changes were required for this compatibility. See the Wiki to learn how to do it. - New status reporting mask to turn on and off what Grbl sends back. This includes machine coordinates, work coordinates, serial RX buffer usage, and planner buffer usage. Expandable to more information on user request, but that’s it for now. - Settings have been completely renumbered to allow for future new settings to be installed without having to constantly reshuffle and renumber all of the settings every time. - All settings masks have been standardized to mean bit 0 = X, bit 1 = Y, and bit 2 = Z, to reduce confusion on how they work. The invert masks used by the internal Grbl system were updated to accommodate this change as well. - New invert probe pin setting, which does what it sounds like. - Fixed a probing cycle bug, where it would freeze intermittently, and removed some redundant code. - Homing may now be set to the origin wherever the limit switches are. Traditionally machine coordinates should always be in negative space, but when limit switches on are on the opposite side, the machine coordinate would be set to -max_travel for the axis. Now you can always make it [0,0,0] via a compile-time option in config.h.

v1.1e: New laser features. G-code parser refactoring. CoreXY homing fix. - Increment to v1.1e due to new laser features. - After several discussions with some prominent laser people, a few tweaks to the new laser mode has been installed. - LASER: M3 behaves in a constant power mode. - LASER: M4 behaves in a dynamic power mode, where the laser power is automatically adjusted based on how fast Grbl is moving relative to the programmed feed rate. This is the same as the CONSTANT_POWER_PER_RATE config.h option in the last version. NOTE: When not in motion in M4, Grbl automatically turns off the laser. Again, it only operates while moving! - LASER: Only G1, G2, and G3 motion modes will turn on the laser. So, this means that G0, G80 motion modes will always keep the laser disabled. No matter if M3/M4 are active! - LASER: A spindle stop override is automatically invoked when a laser is put in a feed hold. This behavior may be disabled by a config.h option. - Lots of little tweaks to the g-code parser to help streamline it a bit. It should no effect how it operates. Generally just added a parser flag to track and execute certain scenarios a little more clearly. - Jog motions now allow line numbers to be passed to it and will be displayed in the status reports. - Fixed a CoreXY homing bug. - Fixed an issue when $13 is changed, WCO isn’t sent immediately. - Altered how spindle PWM is set in the stepper ISR. Updated on a step segment basis now. May need to change this back if there are any oddities from doing this. - Updated some documentation. Clarified why M0 no longer showing up in $G and why a `1.` floating point values are shown with no decimals, like so `1`.

Grbl v1.0e huge beta release. Overrides and new reporting. - Feature: Realtime feed, rapid, and spindle speed overrides. These alter the running machine state within tens of milliseconds! - Feed override: 100%, +/-10%, +/-1% commands with values 1-200% of programmed feed - Rapid override: 100%, 50%, 25% rapid rate commands - Spindle speed override: 100%, +/-10%, +/-1% commands with values 50-200% of programmed speed - Override values have configurable limits and increments in config.h. - Feature: Realtime toggle overrides for spindle stop, flood coolant, and optionally mist coolant - Spindle stop: Enables and disables spindle during a feed hold. Automatically restores last spindles state. - Flood and mist coolant: Immediately toggles coolant state until next toggle or g-code coolant command. - Feature: Jogging mode! Incremental and absolute modes supported. - Grbl accepts jogging-specific commands like $J=X100F50. An axis word and feed rate are required. G20/21 and G90/G91 commands are accepted. - Jog motions can be canceled at any time by a feed hold `!` command. The buffer is automatically flushed. (No resetting required). - Jog motions do not alter the g-code parser state so GUIs don’t have to track what they changed and correct it. - Feature: Laser mode setting. Allows Grbl to execute continuous motions with spindle speed and state changes. - Feature: Significantly improved status reports. Overhauled to cram in more meaningful data and still make it smaller on average. - All available data is now sent by default, but does not appear if it doesn’t change or is not active. - Machine position(MPos) or work position(WPos) is reported but not both at the same time. Instead, the work coordinate offsets (WCO)are sent intermittently whenever it changes or refreshes after 10-30 status reports. Position vectors are easily computed by WPos = MPos - WCO. - All data has changed in some way. Details of changes are in the markdown documents and wiki. - Feature: 16 new realtime commands to control overrides. All in extended-ASCII character space. - While they are not easily typeable and requires a GUI, they can’t be accidentally triggered by some latent character in the g-code program and have tons of room for expansion. - Feature: New substates for HOLD and SAFETY DOOR. A `:x` is appended to the state, where `x` is an integer and indicates a substate. - For example, each integer of a door state describes in what phase the machine is in during parking. Substates are detailed in the documentation. - Feature: With the alarm codes, homing and probe alarms have been expanded with more codes to provide more exact feedback on what caused the alarm. - Feature: New hard limit check upon power-up or reset. If detected, a feedback message to check the limit switches sent immediately after the welcome message. - May be disabled in config.h. - OEM feature: Enable/disable `$RST=` individual commands based on desired behavior in config.h. - OEM feature: Configurable EEPROM wipe to prevent certain data from being deleted during firmware upgrade to a new settings version or `RST=*` command. - OEM feature: Enable/disable the `$I=` build info write string with external EEPROM write example sketch. - This prevents a user from altering the build info string in EEPROM. This requires the vendor to write the string to EEPROM via external means. An Arduino example sketch is provided to accomplish this. This would be useful for contain product data that is retrievable. - Tweak: All feedback has been drastically trimmed to free up flash space for the v1.0 release. - The `$` help message is just one string, listing available commands. - The `$$` settings printout no longer includes descriptions. Only the setting values. (Sorry it’s this or remove overrides!) - Grbl `error:` and `ALARM:` responses now only contain codes. No descriptions. All codes are explained in documentation. - Grbl’s old feedback style may be restored via a config.h, but keep in mind that it will likely not fit into the Arduino’s flash space. - Tweak: Grbl now forces a buffer sync or stop motion whenever a g-code command needs to update and write a value to EEPROM or changes the work coordinate offset. - This addresses two old issues in all prior Grbl versions. First, an EEPROM write requires interrupts to be disabled, including stepper and serial comm. Steps can be lost and data can be corrupted. Second, the work position may not be correlated to the actual machine position, since machine position is derived from the actual current execution state, while work position is based on the g-code parser offset state. They are usually not in sync and the parser state is several motions behind. This forced sync ensures work and machine positions are always correct. - This behavior can be disabled through a config.h option, but it’s not recommended to do so. - Tweak: To make status reports standardized, users can no longer change what is reported via status report mask, except for only toggling machine or work positions. - All other data fields are included in the report and can only be disabled through the config.h file. It’s not recommended to alter this, because GUIs will be expecting this data to be present and may not be compatible. - Tweak: Homing cycle and parking motion no longer report a negative line number in a status report. These will now not report a line number at all. - Tweak: New `[Restoring spindle]` message when restoring from a spindle stop override. Provides feedback what Grbl is doing while the spindle is powering up and a 4.0 second delay is enforced. - Tweak: Override values are reset to 100% upon M2/30. This behavior can be disabled in config.h - Tweak: The planner buffer size has been reduced from 18 to 16 to free up RAM for tracking and controlling overrides. - Tweak: TX buffer size has been increased from 64 to 90 bytes to improve status reporting and overall performance. - Tweak: Removed the MOTION CANCEL state. It was redundant and didn’t affect Grbl’s overall operation by doing so. - Tweak: Grbl’s serial buffer increased by +1 internally, such that 128 bytes means 128, not 127 due to the ring buffer implementation. Long overdue. - Tweak: Altered sys.alarm variable to be set by alarm codes, rather than bit flags. Simplified how it worked overall. - Tweak: Planner buffer and serial RX buffer usage has been combined in the status reports. - Tweak: Pin state reporting has been refactored to report only the pins “triggered” and nothing when not “triggered”. - Tweak: Current machine rate or speed is now included in every report. - Tweak: The work coordinate offset (WCO) and override states only need to be refreshed intermittently or reported when they change. The refresh rates may be altered for each in the config.h file with different idle and busy rates to lessen Grbl’s load during a job. - Tweak: For temporary compatibility to existing GUIs until they are updated, an option to revert back to the old style status reports is available in config.h, but not recommended for long term use. - Tweak: Removed old limit pin state reporting option from config.h in lieu of new status report that includes them. - Tweak: Updated the defaults.h file to include laser mode, altered status report mask, and fix an issue with a missing invert probe pin default. - Refactor: Changed how planner line data is generated and passed to the planner and onto the step generator. By making it a struct variable, this saved significant flash space. - Refactor: Major re-factoring of the planner to incorporate override values and allow for re-calculations fast enough to immediately take effect during operation. No small feat. - Refactor: Re-factored the step segment generator for re-computing new override states. - Refactor: Re-factored spindle_control.c to accommodate the spindle speed overrides and laser mode. - Refactor: Re-factored parts of the codebase for a new jogging mode. Still under development though and slated to be part of the official v1.0 release. Hang tight. - Refactor: Created functions for computing a unit vector and value limiting based on axis maximums to free up more flash. - Refactor: The spindle PWM is now set directly inside of the stepper ISR as it loads new step segments. - Refactor: Moved machine travel checks out of soft limits function into its own since jogging uses this too. - Refactor: Removed coolant_stop() and combined with coolant_set_state(). - Refactor: The serial RX ISR forks off extended ASCII values to quickly assess the new override realtime commands. - Refactor: Altered some names of the step control flags. - Refactor: Improved efficiency of the serial RX get buffer count function. - Refactor: Saved significant flash by removing and combining print functions. Namely the uint8 base10 and base2 functions. - Refactor: Moved the probe state check in the main stepper ISR to improve its efficiency. - Refactor: Single character printPgmStrings() went converted to direct serial_write() commands to save significant flash space. - Documentation: Detailed Markdown documents on error codes, alarm codes, messages, new real-time commands, new status reports, and how jogging works. More to come later and will be posted on the Wiki as well. - Documentation: CSV files for quick importing of Grbl error and alarm codes. - Bug Fix: Applied v0.9 master fixes to CoreXY homing. - Bug Fix: The print float function would cause Grbl to crash if a value was 1e6 or greater. Increased the buffer by 3 bytes to help prevent this in the future. - Bug Fix: Build info and startup string EEPROM restoring was not writing the checksum value. - Bug Fix: Corrected an issue with safety door restoring the proper spindle and coolant state. It worked before, but breaks with laser mode that can continually change spindle state per planner block. - Bug Fix: Move system position and probe position arrays out of the system_t struct. Ran into some compiling errors that were hard to track down as to why. Moving them out fixed it.

Settings refactoring. Bug fixes. Misc new features. This is likely the last major change to the v0.9 code base before push to master. Only two minor things remain on the agenda (CoreXY support, force clear EEPROM, and an extremely low federate bug). - NEW! Grbl is now compile-able and may be flashed directly through the Arduino IDE. Only minor changes were required for this compatibility. See the Wiki to learn how to do it. - New status reporting mask to turn on and off what Grbl sends back. This includes machine coordinates, work coordinates, serial RX buffer usage, and planner buffer usage. Expandable to more information on user request, but that’s it for now. - Settings have been completely renumbered to allow for future new settings to be installed without having to constantly reshuffle and renumber all of the settings every time. - All settings masks have been standardized to mean bit 0 = X, bit 1 = Y, and bit 2 = Z, to reduce confusion on how they work. The invert masks used by the internal Grbl system were updated to accommodate this change as well. - New invert probe pin setting, which does what it sounds like. - Fixed a probing cycle bug, where it would freeze intermittently, and removed some redundant code. - Homing may now be set to the origin wherever the limit switches are. Traditionally machine coordinates should always be in negative space, but when limit switches on are on the opposite side, the machine coordinate would be set to -max_travel for the axis. Now you can always make it [0,0,0] via a compile-time option in config.h. (Soft limits routine was updated to account for this as well.) - Probe coordinate message immediately after a probing cycle may now be turned off via a compile-time option in config.h. By default the probing location is always reported. - Reduced the N_ARC_CORRECTION default value to reflect the changes in how circles are generated by an arc tolerance, rather than a fixed arc segment setting. - Increased the incoming line buffer limit from 70 to 80 characters.

v1.1c: New sleep mode. Laser mode and other bug fixes. - New $SLP sleep mode that will disable spindle, coolant, and stepper enable pins. Allows users to disable their steppers without having to alter their settings. A reset is required to exit and re-initializes in alarm state. - Laser mode wasn’t updating the spindle PWM correctly (effected spindle speed overrides) and not checking for modal states either. Fixed both issues. - While in laser mode, parking motions are ignored, since the power off delay with the retract motion would burn the material. It will just turn off and not move. A restore immediately powers up and resumes. No delays. - Changing rpm max and min settings did not update the spindle PWM calculations. Now fixed. - Increased default planner buffer from 16 to 17 block. It seems to be stable, but need to monitor this carefully. - Removed software debounce routine for limit pins. Obsolete. - Fixed a couple parking motion bugs. One related to restoring incorrectly and the other the parking rate wasn’t compatible with the planner structs. - Fixed a bug caused by refactoring the critical alarms in a recent push. Soft limits weren’t invoking a critical alarm. - Updated the documentation with the new sleep feature and added some more details to the change summary.

Provides feedback what Grbl is doing while the spindle is powering up and a 4.0 second delay is enforced. - Tweak: Override values are reset to 100% upon M2/30. This behavior can be disabled in config.h - Tweak: The planner buffer size has been reduced from 18 to 16 to free up RAM for tracking and controlling overrides. - Tweak: TX buffer size has been increased from 64 to 90 bytes to improve status reporting and overall performance. - Tweak: Removed the MOTION CANCEL state. It was redundant and didn’t affect Grbl’s overall operation by doing so. - Tweak: Grbl’s serial buffer increased by +1 internally, such that 128 bytes means 128, not 127 due to the ring buffer implementation. Long overdue. - Tweak: Altered sys.alarm variable to be set by alarm codes, rather than bit flags. Simplified how it worked overall. - Tweak: Planner buffer and serial RX buffer usage has been combined in the status reports. - Tweak: Pin state reporting has been refactored to report only the pins “triggered” and nothing when not “triggered”. - Tweak: Current machine rate or speed is now included in every report. - Tweak: The work coordinate offset (WCO) and override states only need to be refreshed intermittently or reported when they change. The refresh rates may be altered for each in the config.h file with different idle and busy rates to lessen Grbl’s load during a job. - Tweak: For temporary compatibility to existing GUIs until they are updated, an option to revert back to the old style status reports is available in config.h, but not recommended for long term use. - Tweak: Removed old limit pin state reporting option from config.h in lieu of new status report that includes them. - Tweak: Updated the defaults.h file to include laser mode, altered status report mask, and fix an issue with a missing invert probe pin default. - Refactor: Changed how planner line data is generated and passed to the planner and onto the step generator. By making it a struct variable, this saved significant flash space. - Refactor: Major re-factoring of the planner to incorporate override values and allow for re-calculations fast enough to immediately take effect during operation. No small feat. - Refactor: Re-factored the step segment generator for re-computing new override states. - Refactor: Re-factored spindle_control.c to accommodate the spindle speed overrides and laser mode. - Refactor: Re-factored parts of the codebase for a new jogging mode. Still under development though and slated to be part of the official v1.0 release. Hang tight. - Refactor: Created functions for computing a unit vector and value limiting based on axis maximums to free up more flash. - Refactor: The spindle PWM is now set directly inside of the stepper ISR as it loads new step segments. - Refactor: Moved machine travel checks out of soft limits function into its own since jogging uses this too. - Refactor: Removed coolant_stop() and combined with coolant_set_state(). - Refactor: The serial RX ISR forks off extended ASCII values to quickly assess the new override realtime commands. - Refactor: Altered some names of the step control flags. - Refactor: Improved efficiency of the serial RX get buffer count function. - Refactor: Saved significant flash by removing and combining print functions. Namely the uint8 base10 and base2 functions. - Refactor: Moved the probe state check in the main stepper ISR to improve its efficiency. - Refactor: Single character printPgmStrings() went converted to direct serial_write() commands to save significant flash space. - Documentation: Detailed Markdown documents on error codes, alarm codes, messages, new real-time commands, new status reports, and how jogging works. More to come later and will be posted on the Wiki as well. - Documentation: CSV files for quick importing of Grbl error and alarm codes. - Bug Fix: Applied v0.9 master fixes to CoreXY homing. - Bug Fix: The print float function would cause Grbl to crash if a value was 1e6 or greater. Increased the buffer by 3 bytes to help prevent this in the future. - Bug Fix: Build info and startup string EEPROM restoring was not writing the checksum value. - Bug Fix: Corrected an issue with safety door restoring the proper spindle and coolant state. It worked before, but breaks with laser mode that can continually change spindle state per planner block. - Bug Fix: Move system position and probe position arrays out of the system_t struct. Ran into some compiling errors that were hard to track down as to why. Moving them out fixed it.

Grbl v1.0e huge beta release. Overrides and new reporting. - Feature: Realtime feed, rapid, and spindle speed overrides. These alter the running machine state within tens of milliseconds! - Feed override: 100%, +/-10%, +/-1% commands with values 1-200% of programmed feed - Rapid override: 100%, 50%, 25% rapid rate commands - Spindle speed override: 100%, +/-10%, +/-1% commands with values 50-200% of programmed speed - Override values have configurable limits and increments in config.h. - Feature: Realtime toggle overrides for spindle stop, flood coolant, and optionally mist coolant - Spindle stop: Enables and disables spindle during a feed hold. Automatically restores last spindles state. - Flood and mist coolant: Immediately toggles coolant state until next toggle or g-code coolant command. - Feature: Jogging mode! Incremental and absolute modes supported. - Grbl accepts jogging-specific commands like $J=X100F50. An axis word and feed rate are required. G20/21 and G90/G91 commands are accepted. - Jog motions can be canceled at any time by a feed hold `!` command. The buffer is automatically flushed. (No resetting required). - Jog motions do not alter the g-code parser state so GUIs don’t have to track what they changed and correct it. - Feature: Laser mode setting. Allows Grbl to execute continuous motions with spindle speed and state changes. - Feature: Significantly improved status reports. Overhauled to cram in more meaningful data and still make it smaller on average. - All available data is now sent by default, but does not appear if it doesn’t change or is not active. - Machine position(MPos) or work position(WPos) is reported but not both at the same time. Instead, the work coordinate offsets (WCO)are sent intermittently whenever it changes or refreshes after 10-30 status reports. Position vectors are easily computed by WPos = MPos - WCO. - All data has changed in some way. Details of changes are in the markdown documents and wiki. - Feature: 16 new realtime commands to control overrides. All in extended-ASCII character space. - While they are not easily typeable and requires a GUI, they can’t be accidentally triggered by some latent character in the g-code program and have tons of room for expansion. - Feature: New substates for HOLD and SAFETY DOOR. A `:x` is appended to the state, where `x` is an integer and indicates a substate. - For example, each integer of a door state describes in what phase the machine is in during parking. Substates are detailed in the documentation. - Feature: With the alarm codes, homing and probe alarms have been expanded with more codes to provide more exact feedback on what caused the alarm. - Feature: New hard limit check upon power-up or reset. If detected, a feedback message to check the limit switches sent immediately after the welcome message. - May be disabled in config.h. - OEM feature: Enable/disable `$RST=` individual commands based on desired behavior in config.h. - OEM feature: Configurable EEPROM wipe to prevent certain data from being deleted during firmware upgrade to a new settings version or `RST=*` command. - OEM feature: Enable/disable the `$I=` build info write string with external EEPROM write example sketch. - This prevents a user from altering the build info string in EEPROM. This requires the vendor to write the string to EEPROM via external means. An Arduino example sketch is provided to accomplish this. This would be useful for contain product data that is retrievable. - Tweak: All feedback has been drastically trimmed to free up flash space for the v1.0 release. - The `$` help message is just one string, listing available commands. - The `$$` settings printout no longer includes descriptions. Only the setting values. (Sorry it’s this or remove overrides!) - Grbl `error:` and `ALARM:` responses now only contain codes. No descriptions. All codes are explained in documentation. - Grbl’s old feedback style may be restored via a config.h, but keep in mind that it will likely not fit into the Arduino’s flash space. - Tweak: Grbl now forces a buffer sync or stop motion whenever a g-code command needs to update and write a value to EEPROM or changes the work coordinate offset. - This addresses two old issues in all prior Grbl versions. First, an EEPROM write requires interrupts to be disabled, including stepper and serial comm. Steps can be lost and data can be corrupted. Second, the work position may not be correlated to the actual machine position, since machine position is derived from the actual current execution state, while work position is based on the g-code parser offset state. They are usually not in sync and the parser state is several motions behind. This forced sync ensures work and machine positions are always correct. - This behavior can be disabled through a config.h option, but it’s not recommended to do so. - Tweak: To make status reports standardized, users can no longer change what is reported via status report mask, except for only toggling machine or work positions. - All other data fields are included in the report and can only be disabled through the config.h file. It’s not recommended to alter this, because GUIs will be expecting this data to be present and may not be compatible. - Tweak: Homing cycle and parking motion no longer report a negative line number in a status report. These will now not report a line number at all. - Tweak: New `[Restoring spindle]` message when restoring from a spindle stop override. Provides feedback what Grbl is doing while the spindle is powering up and a 4.0 second delay is enforced. - Tweak: Override values are reset to 100% upon M2/30. This behavior can be disabled in config.h - Tweak: The planner buffer size has been reduced from 18 to 16 to free up RAM for tracking and controlling overrides. - Tweak: TX buffer size has been increased from 64 to 90 bytes to improve status reporting and overall performance. - Tweak: Removed the MOTION CANCEL state.

Settings refactoring. Bug fixes. Misc new features. This is likely the last major change to the v0.9 code base before push to master. Only two minor things remain on the agenda (CoreXY support, force clear EEPROM, and an extremely low federate bug). - NEW! Grbl is now compile-able and may be flashed directly through the Arduino IDE. Only minor changes were required for this compatibility. See the Wiki to learn how to do it. - New status reporting mask to turn on and off what Grbl sends back. This includes machine coordinates, work coordinates, serial RX buffer usage, and planner buffer usage. Expandable to more information on user request, but that’s it for now. - Settings have been completely renumbered to allow for future new settings to be installed without having to constantly reshuffle and renumber all of the settings every time. - All settings masks have been standardized to mean bit 0 = X, bit 1 = Y, and bit 2 = Z, to reduce confusion on how they work. The invert masks used by the internal Grbl system were updated to accommodate this change as well. - New invert probe pin setting, which does what it sounds like. - Fixed a probing cycle bug, where it would freeze intermittently, and removed some redundant code. - Homing may now be set to the origin wherever the limit switches are. Traditionally machine coordinates should always be in negative space, but when limit switches on are on the opposite side, the machine coordinate would be set to -max_travel for the axis. Now you can always make it [0,0,0] via a compile-time option in config.h. (Soft limits routine was updated to account for this as well.) - Probe coordinate message immediately after a probing cycle may now be turned off via a compile-time option in config.h. By default the probing location is always reported. - Reduced the N_ARC_CORRECTION default value to reflect the changes in how circles are generated by an arc tolerance, rather than a fixed arc segment setting. - Increased the incoming line buffer limit from 70 to 80 characters. Had some extra memory space to invest into this. - Fixed a bug where tool number T was not being tracked and reported correctly. - Added a print free memory function for debugging purposes. Not used otherwise. - Realtime rate report should now work during feed holds, but it hasn’t been tested yet. - Updated the streaming scripts with MIT-license and added the simple streaming to the main stream.py script to allow for settings to be sent. - Some minor code refactoring to improve flash efficiency. Reduced the flash by several hundred KB, which was re-invested in some of these new features.

Re-factored system states and alarm management. Serial baud support greater than 57600. - Refactored system states to be more clear and concise. Alarm locks processes when position is unknown to indicate to user something has gone wrong. - Changed mc_alarm to mc_reset, which now manages the system reset function. Centralizes it. - Renamed '$X' kill homing lock to kill alarm lock. - Created an alarm error reporting method to clear up what is an alarm: message vs a status error: message. For GUIs mainly. Alarm codes are negative. Status codes are positive. - Serial baud support upto 115200. Previous baudrate calc was unstable for 57600 and above. - Alarm state locks out all g-code blocks, including startup scripts, but allows user to access settings and internal commands. For example, to disable hard limits, if they are problematic. - Hard limits do not respond in an alarm state. - Fixed a problem with the hard limit interrupt during the homing cycle. The interrupt register is still active during the homing cycle and still signal the interrupt to trigger when re-enabled. Instead, just disabled the register. - Homing rate adjusted. All axes move at homing seek rate, regardless of how many axes move at the same time. This is unlike how the stepper module does it as a point to point rate. - New config.h settings to disable the homing rate adjustment and the force homing upon powerup. - Reduced the number of startup lines back down to 2 from 3. This discourages users from placing motion block in there, which can be very dangerous. - Startup blocks now run only after an alarm-free reset or after a homing cycle. Does not run when $X kill is called. For satefy reasons

Lots of re-organization and cleaning-up. Some bug fixes. - Added a new source and header file called system. These files contain the system commands and variables, as well as all of the system headers and standard libraries Grbl uses. Centralizing some of the code. - Re-organized the include headers throughout the source code. - ENABLE_M7 define was missing from config.h. Now there. - SPINDLE_MAX_RPM and SPINDLE_MIN_RPM now defined in config.h. No uncommenting to prevent user issues. Minimum spindle RPM now provides the lower, near 0V, scale adjustment, i.e. some spindles can go really slow so why use up our 256 voltage bins for them? - Remove some persistent variables from coolant and spindle control. They were redundant. - Removed a VARIABLE_SPINDLE define in cpu_map.h that shouldn’t have been there. - Changed the DEFAULT_ARC_TOLERANCE to 0.002mm to improve arc tracing. Before we had issues with performance, no longer. - Fixed a bug with the hard limits and the software debounce feature enabled. The invert limit pin setting wasn’t honored. - Fixed a bug with the homing direction mask. Now is like it used to be. At least for now. - Re-organized main.c to serve as only as the reset/initialization routine. Makes things a little bit clearer in terms of execution procedures. - Re-organized protocol.c as the overall master control unit for execution procedures. Not quite there yet, but starting to make a little more sense in how things are run. - Removed updating of old settings records. So many new settings have been added that it’s not worth adding the code to migrate old user settings. - Tweaked spindle_control.c a bit and made it more clear and consistent with other parts of Grbl. - Tweaked the stepper disable bit code in stepper.c. Requires less flash memory.

New EEPROM restore functions. - Tweaked the previous EEPROM restore implementation and added new functionality. - `$RST=$` restores the `$$` grbl settings back to firmware defaults, which are set when compiled. - `$RST=#` restores the `$#` parameters in EEPROM. At times it’s useful to clear these and start over, rather than manually writing each entry. -`$RST=*` wipe all of the data in EEPROM that Grbl uses and restores them to defaults. This includes `$$` settings, `$#` parameters, `$N` startup lines, and `$i` build info string. NOTE: This doesn’t write zeros throughout the EEPROM. It only writes where Grbl looks for data. For a complete wipe, please use the Arduino IDE’s EEPROM clear example. - Refactored the restore and wipe functions in settings.c to accommodate the new commands.

Had some extra memory space to invest into this. - Fixed a bug where tool number T was not being tracked and reported correctly. - Added a print free memory function for debugging purposes. Not used otherwise. - Realtime rate report should now work during feed holds, but it hasn’t been tested yet. - Updated the streaming scripts with MIT-license and added the simple streaming to the main stream.py script to allow for settings to be sent. - Some minor code refactoring to improve flash efficiency. Reduced the flash by several hundred KB, which was re-invested in some of these new features.

Settings refactoring. Bug fixes. Misc new features. This is likely the last major change to the v0.9 code base before push to master. Only two minor things remain on the agenda (CoreXY support, force clear EEPROM, and an extremely low federate bug). - NEW! Grbl is now compile-able and may be flashed directly through the Arduino IDE. Only minor changes were required for this compatibility. See the Wiki to learn how to do it. - New status reporting mask to turn on and off what Grbl sends back. This includes machine coordinates, work coordinates, serial RX buffer usage, and planner buffer usage. Expandable to more information on user request, but that’s it for now. - Settings have been completely renumbered to allow for future new settings to be installed without having to constantly reshuffle and renumber all of the settings every time. - All settings masks have been standardized to mean bit 0 = X, bit 1 = Y, and bit 2 = Z, to reduce confusion on how they work. The invert masks used by the internal Grbl system were updated to accommodate this change as well. - New invert probe pin setting, which does what it sounds like. - Fixed a probing cycle bug, where it would freeze intermittently, and removed some redundant code. - Homing may now be set to the origin wherever the limit switches are. Traditionally machine coordinates should always be in negative space, but when limit switches on are on the opposite side, the machine coordinate would be set to -max_travel for the axis. Now you can always make it [0,0,0] via a compile-time option in config.h.
