coolant_control.c - coolant control methods
Homing alarm upon no switch. Licensing update. - Homing cycle failure reports alarm feedback when the homing cycle is exited via a reset, interrupted by a safety door switch, or does not find the limit switch. - Homing cycle bug fix when not finding the limit switch. It would just idle before, but now will exit with an alarm. - Licensing update. Corrected licensing according to lawyer recommendations. Removed references to other Grbl versions.

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.

Cleaned up variable spindle output (PWM). Code and config comments. - Variable spindle speed output as a configuration option. Thanks @EliteEng! When enabled, the Z-limit (D11) and spindle enable(D12) pins switch to allow access to the hardware PWM output on pin D11. Otherwise, everything should work as it does. - Removed option for inverting the spindle and coolant enable pins. This is a safety hazard, especially for the spindle. When Grbl initializes, all pins are momentarily low until it finishes booting. If an invert is enabled, this means the spindles can be energized briefly during this time. If users need signal inversion, it’s recommended to just wire in an inversion circuit instead. - Cleared out references to spindle variable output in terms of step signal. This isn’t complete and requires more deliberation before installing. - Cleared up and cleaned up some code and config comments.

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.

COOLANT_FLOOD_DDR |= (1 << COOLANT_FLOOD_BIT); // Configure as output pin
Cleaned up variable spindle output (PWM). Code and config comments. - Variable spindle speed output as a configuration option. Thanks @EliteEng! When enabled, the Z-limit (D11) and spindle enable(D12) pins switch to allow access to the hardware PWM output on pin D11. Otherwise, everything should work as it does. - Removed option for inverting the spindle and coolant enable pins. This is a safety hazard, especially for the spindle. When Grbl initializes, all pins are momentarily low until it finishes booting. If an invert is enabled, this means the spindles can be energized briefly during this time. If users need signal inversion, it’s recommended to just wire in an inversion circuit instead. - Cleared out references to spindle variable output in terms of step signal. This isn’t complete and requires more deliberation before installing. - Cleared up and cleaned up some code and config comments.

#ifdef ENABLE_M7
Added coolant control (M7*, M8, M9). Mist control can be enabled via config.h. - Added coolant control! Flood control (M8) functions on analog pin 0. Mist control (M7) is compile-time optional and is on analog pin 1. (Use only if you have multiple coolants on your system). Based on work by @openpnp. - Fixed some variable assignments in spindle control.

v1.1d: Tweaked interface a bit. Added realtime spindle speed and build option data. Minor bug fixes. - Increment to v1.1d due to interface tweaks. - Based on GUI dev feedback, the toggle overrides report was removed and replace with showing “accessory state”. This shows a character if a particular accessory is enabled, like the spindle or flood coolant. These can be directly altered by the toggle overrides, so when they execute, a GUI will be able to observe the state altering as feedback. - Altered the real-time feed rate to show real-time spindle speed as well. It was an over-sight on my part. It’s needed because it’s hard to know what the current spindle speed is when overrides are altering it. Especially during something like a laser cutting job when its important to know how spindle speed overrides are effecting things. - Real-time spindle speed is not shown if VARIABLE_SPINDLE is disabled. The old real-time feed rate data field will show instead. - Compile-time option data is now included in another message immediately following the build info version string, starting with `[OPT:`. A character code follows the data type name with each indicating a particular option enabled or disabled. This will help immensely with debugging Grbl as well as help GUIs know exactly how Grbl was compiled. - These interface changes are detailed in the updated documentation. - Reduced the default planner buffer size from 17 to 16. Needed to free up some memory… - For increasing the serial TX buffer size from 90 to 104 bytes. The addition of real-time spindle speeds and accessory enable data required a bigger buffer. This is to ensure Grbl is performing at optimal levels. - Refactored parts of the spindle and coolant control code to make it more consistent to each other and how it was called. It was a little messy. The changes made it easier to track what each function call was doing based on what was calling it. - Created a couple of new get_state functions for the spindle and coolant. These are called by the accessory state report to look directly at the pin state, rather than track how it was set. This guarantees that the state is reported correctly. - Updated the g-code parser, parking motion, sleep mode, and spindle stop calls to refactored spindle and coolant code. - Added a compile-time option to enable homing individual axes, rather than having only the main homing cycle. The actual use case for this is pretty rare. It’s not recommended you enable this, unless you have a specific application for it. Otherwise, just alter the homing cycle itself. - Refactored the printFloat() function to not show a decimal point if there are no trailing values after it. For example, `1.` now shows `1`. - Fixed an issue regarding spindle speed overrides no being applied to blocks without motions. - Removed the toggle_ovr_mask system variable and replaced with spindle_stop_ovr system variable. Coolant toggles don’t need to be tracked. - Updated README

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.

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.

v1.1d: Tweaked interface a bit. Added realtime spindle speed and build option data. Minor bug fixes. - Increment to v1.1d due to interface tweaks. - Based on GUI dev feedback, the toggle overrides report was removed and replace with showing “accessory state”. This shows a character if a particular accessory is enabled, like the spindle or flood coolant. These can be directly altered by the toggle overrides, so when they execute, a GUI will be able to observe the state altering as feedback. - Altered the real-time feed rate to show real-time spindle speed as well. It was an over-sight on my part. It’s needed because it’s hard to know what the current spindle speed is when overrides are altering it. Especially during something like a laser cutting job when its important to know how spindle speed overrides are effecting things. - Real-time spindle speed is not shown if VARIABLE_SPINDLE is disabled. The old real-time feed rate data field will show instead. - Compile-time option data is now included in another message immediately following the build info version string, starting with `[OPT:`. A character code follows the data type name with each indicating a particular option enabled or disabled. This will help immensely with debugging Grbl as well as help GUIs know exactly how Grbl was compiled. - These interface changes are detailed in the updated documentation. - Reduced the default planner buffer size from 17 to 16. Needed to free up some memory… - For increasing the serial TX buffer size from 90 to 104 bytes. The addition of real-time spindle speeds and accessory enable data required a bigger buffer. This is to ensure Grbl is performing at optimal levels. - Refactored parts of the spindle and coolant control code to make it more consistent to each other and how it was called. It was a little messy. The changes made it easier to track what each function call was doing based on what was calling it. - Created a couple of new get_state functions for the spindle and coolant. These are called by the accessory state report to look directly at the pin state, rather than track how it was set. This guarantees that the state is reported correctly. - Updated the g-code parser, parking motion, sleep mode, and spindle stop calls to refactored spindle and coolant code. - Added a compile-time option to enable homing individual axes, rather than having only the main homing cycle. The actual use case for this is pretty rare. It’s not recommended you enable this, unless you have a specific application for it. Otherwise, just alter the homing cycle itself. - Refactored the printFloat() function to not show a decimal point if there are no trailing values after it. For example, `1.` now shows `1`. - Fixed an issue regarding spindle speed overrides no being applied to blocks without motions. - Removed the toggle_ovr_mask system variable and replaced with spindle_stop_ovr system variable. Coolant toggles don’t need to be tracked. - Updated README

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.

This will help immensely with debugging Grbl as well as help GUIs know exactly how Grbl was compiled. - These interface changes are detailed in the updated documentation. - Reduced the default planner buffer size from 17 to 16. Needed to free up some memory… - For increasing the serial TX buffer size from 90 to 104 bytes. The addition of real-time spindle speeds and accessory enable data required a bigger buffer. This is to ensure Grbl is performing at optimal levels. - Refactored parts of the spindle and coolant control code to make it more consistent to each other and how it was called. It was a little messy. The changes made it easier to track what each function call was doing based on what was calling it. - Created a couple of new get_state functions for the spindle and coolant. These are called by the accessory state report to look directly at the pin state, rather than track how it was set. This guarantees that the state is reported correctly. - Updated the g-code parser, parking motion, sleep mode, and spindle stop calls to refactored spindle and coolant code. - Added a compile-time option to enable homing individual axes, rather than having only the main homing cycle. The actual use case for this is pretty rare. It’s not recommended you enable this, unless you have a specific application for it. Otherwise, just alter the homing cycle itself. - Refactored the printFloat() function to not show a decimal point if there are no trailing values after it. For example, `1.` now shows `1`. - Fixed an issue regarding spindle speed overrides no being applied to blocks without motions. - Removed the toggle_ovr_mask system variable and replaced with spindle_stop_ovr system variable. Coolant toggles don’t need to be tracked. - Updated README

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.

v1.1d: Tweaked interface a bit. Added realtime spindle speed and build option data. Minor bug fixes. - Increment to v1.1d due to interface tweaks. - Based on GUI dev feedback, the toggle overrides report was removed and replace with showing “accessory state”. This shows a character if a particular accessory is enabled, like the spindle or flood coolant. These can be directly altered by the toggle overrides, so when they execute, a GUI will be able to observe the state altering as feedback. - Altered the real-time feed rate to show real-time spindle speed as well. It was an over-sight on my part. It’s needed because it’s hard to know what the current spindle speed is when overrides are altering it. Especially during something like a laser cutting job when its important to know how spindle speed overrides are effecting things. - Real-time spindle speed is not shown if VARIABLE_SPINDLE is disabled.

Minor re-factoring. Fix an issue with parking and spindle restore. - Altered the report counters to be count down, rather than count up. Simplified some of the logic. - Fixed an issue with parking restore. The spindle state would disable then reenable. - Clarified some of the config.h descriptions. - Moved the compile-time checks from config.h to grbl.h. They don’t belong in the config.h file. - Refactored the initialization of the system variables in main.c. System position and probe position were undefined when power cycled, but were zero anyway. Added clear vector code to make it explicit.

Added coolant control (M7*, M8, M9). Mist control can be enabled via config.h. - Added coolant control! Flood control (M8) functions on analog pin 0. Mist control (M7) is compile-time optional and is on analog pin 1. (Use only if you have multiple coolants on your system). Based on work by @openpnp. - Fixed some variable assignments in spindle control.

Lot of refactoring for the future. CoreXY support. - Rudimentary CoreXY kinematics support. Didn’t test, but homing and feed holds should work. See config.h. Please report successes and issues as we find bugs. - G40 (disable cutter comp) is now “supported”. Meaning that Grbl will no longer issue an error when typically sent in g-code program header. - Refactored coolant and spindle state setting into separate functions for future features. - Configuration option for fixing homing behavior when there are two limit switches on the same axis sharing an input pin. - Created a new “grbl.h” that will eventually be used as the main include file for Grbl. Also will help simply uploading through the Arduino IDE - Separated out the alarms execution flags from the realtime (used be called runtime) execution flag variable. Now reports exactly what caused the alarm. Expandable for new alarms later on. - Refactored the homing cycle to support CoreXY. - Applied @EliteEng updates to Mega2560 support. Some pins were reconfigured. - Created a central step to position and vice versa function. Needed for non-traditional cartesian machines. Should make it easier later. - Removed the new CPU map for the Uno. No longer going to used. There will be only one configuration to keep things uniform.

For example, `1.` now shows `1`. - Fixed an issue regarding spindle speed overrides no being applied to blocks without motions. - Removed the toggle_ovr_mask system variable and replaced with spindle_stop_ovr system variable. Coolant toggles don’t need to be tracked. - Updated README

// G-code parser entry-point for setting coolant state. Forces a planner buffer sync and bails
// if an abort or check-mode is active.
void coolant_sync(uint8_t mode)
Lot of refactoring for the future. CoreXY support. - Rudimentary CoreXY kinematics support. Didn’t test, but homing and feed holds should work. See config.h. Please report successes and issues as we find bugs. - G40 (disable cutter comp) is now “supported”. Meaning that Grbl will no longer issue an error when typically sent in g-code program header. - Refactored coolant and spindle state setting into separate functions for future features. - Configuration option for fixing homing behavior when there are two limit switches on the same axis sharing an input pin. - Created a new “grbl.h” that will eventually be used as the main include file for Grbl. Also will help simply uploading through the Arduino IDE - Separated out the alarms execution flags from the realtime (used be called runtime) execution flag variable. Now reports exactly what caused the alarm. Expandable for new alarms later on. - Refactored the homing cycle to support CoreXY. - Applied @EliteEng updates to Mega2560 support. Some pins were reconfigured. - Created a central step to position and vice versa function. Needed for non-traditional cartesian machines. Should make it easier later. - Removed the new CPU map for the Uno. No longer going to used. There will be only one configuration to keep things uniform.

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.
