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.

Optimized planner re-write. Significantly faster. Full arc support enabled by rotation matrix approach. - Significant improvements in the planner. Removed or reordered repetitive and expensive calculations by order of importance: recalculating unchanged blocks, trig functions [sin(), cos(), tan()], sqrt(), divides, and multiplications. Blocks long enough for nominal speed to be guaranteed to be reached ignored by planner. Done by introducing two uint8_t flags per block. Reduced computational overhead by an order of magnitude. - Arc motion generation completely re-written and optimized. Now runs with acceleration planner. Removed all but one trig function (atan2) from initialization. Streamlined computations. Segment target locations generated by vector transformation and small angle approximation. Arc path correction implemented for accumulated error of approximation and single precision calculation of Arduino. Bug fix in message passing.

#define motion_control_h
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.

Minor updates to line number feature. - Changed line number integer types from unsigned to signed int32. G-code mandates values cannot exceed 99999. Negative values can be used to indicate certain modes. - Homing cycle line number changed to -1, as an indicator. - Fixed a reporting define for the spindle states that was broken by the last merge.

Added grbl planner Matlab simulator for test reference. Updated line number compile-time option. - Added a grbl planner simulation tool that was written in Matlab and Python. It was used to visualize the inner workings of the planner as a program is streamed to it. The simulation assumes that the planner buffer is empty, then filled, and kept filled. This is mainly for users to see how the planner works. - Updated some of the compile-time ifdefs when enabling line numbers. The leaving the un-used line numbers in the function calls eats a non-neglible amount of flash memory. So the new if-defs remove them.

Updated variable spindle and new probing. Minor bug fixes. - Minor bug fix for variable spindle PWM output. Values smaller than the minimum RPM for the spindle would overflow the PWM value. Thanks Rob! - Created an optional minimum spindle PWM low-mark value as a compile-time option. This is for special circumstances when the PWM has to be at a certain level to be read by the spindle controller. - Refactored the new probing commands (G38.3, G38.4, G38.5) code to work better with the rest of Grbl’s systems. - Refactored mc_probe() and mc_arc() to accept the mode of the command, i.e. clockwise vs counter, toward vs away, etc. This is to make these functions independent of gcode state variables. - Removed the pull off motion in the probing cycle. This is not an official operation and was added for user simplicity, but wrongly did so. So bye bye. - Created a configure probe invert mask function to handle the different probe pin setting and probing cycle modes with a single mask. - Minor bug fix with reporting motion modes via $G. G38.2 wasn’t showing up. It now does, along with the other new probing commands. - Refactored some of the new pin configurations for the future of Grbl. -

#ifdef USE_LINE_NUMBERS
Major g-code parser overhaul. 100%* compliant. Other related updates. - Completely overhauled the g-code parser. It’s now 100%* compliant. (* may have some bugs). Being compliant, here are some of the major differences. - SMALLER and JUST AS FAST! A number of optimizations were found that sped things up and allowed for the more thorough error-checking to be installed without a speed hit. Trimmed a lot of ‘fat’ in the parser and still was able to make it significantly smaller than it was. - No default feed rate setting! Removed completely! This doesn’t exist in the g-code standard. So, it now errors out whenever it’s undefined for motions that require it (G1/2/3/38.2). - Any g-code parser error expunges the ENTIRE block. This means all information is lost and not passed on to the running state. Before some of the states would remain, which could have led to some problems. - If the g-code block passes all of the error-checks, the g-code state is updated and all motions are executed according to the order of execution. - Changes in spindle speed, when already running, will update the output pin accordingly. This fixes a bug, where it wouldn’t update the speed. - Update g-code parser error reporting. Errors now return detailed information of what exact went wrong. The most common errors return a short text description. For less common errors, the parser reports ‘Invalid gcode ID:20’, where 20 is a error ID. A list of error code IDs and their descriptions will be documented for user reference elsewhere to save flash space. - Other notable changes: - Added a print integer routine for uint8 variables. This saved significant flash space by switching from a heavier universal print integer routine. - Saved some flash space with our own short hypotenuse calculation - Some arc computation flash and memory optimizations.

Fixed minor bugs in planner. Increased max dwell time. Long slope bug stop-gap solution note. - Fixed the planner TODO regarding minimum nominal speeds. Re-arranged calculations to be both more efficient and guaranteed to be greater than zero. - Missed a parenthesis location on the rate_delta calculation. Should fix a nearly in-perceptible issue with incorrect acceleration ramping in diagonal directions. - Increased maximum dwell time from 6.5sec to an 18hour max. A crazy amount more, but that's how the math works out. - Converted the internal feedrate values to mm/min only, as it was switching between mm/min to mm/sec and back to mm/min. Also added a feedrate > 0 check in gcode.c. - Identified the long slope at the end of rapid de/ac-celerations noted by stephanix. Problem with the numerical integration truncation error between the exact solution of estimate_acceleration_distance and how grbl actually performs the acceleration ramps discretely. Increasing the ACCELERATION_TICKS_PER_SECOND in config.h helps fix this problem. Investigating further.

// Dwell for a specific number of seconds
Limit pin internal pull-resistors enabled. Re-wrote read_double() function. Correctly changed all 'double's to 'float's. - Limit pin internal pull-resistors now enabled. Normal high operation. This will be the standard going forward. - Updated all of the 'double' variable types to 'float' to reflect what happens when compiled for the Arduino. Also done for compatibility reasons to @jgeisler0303 's Grbl simulator code. - G-code parser will now ignore 'E' exponent values, since they are reserved g-code characters for some machines. Thanks @csdexter! - The read_double() function was re-written and optimized for use in Grbl. The strtod() avr lib was removed.

New startup script setting. New dry run, check gcode switches. New system state variable. Lots of reorganizing. (All v0.8 features installed. Still likely buggy, but now thourough testing will need to start to squash them all. As soon as we're done, this will be pushed to master and v0.9 development will be started. Please report ANY issues to us so we can get this rolled out ASAP.) - User startup script! A user can now save one (up to 5 as compile-time option) block of g-code in EEPROM memory. This will be run everytime Grbl resets. Mainly to be used as a way to set your preferences, like G21, G54, etc. - New dry run and check g-code switches. Dry run moves ALL motions at rapids rate ignoring spindle, coolant, and dwell commands. For rapid physical proofing of your code. The check g-code switch ignores all motion and provides the user a way to check if there are any errors in their program that Grbl may not like. - Program restart! (sort of). Program restart is typically an advanced feature that allows users to restart a program mid-stream. The check g-code switch can perform this feature by enabling the switch at the start of the program, and disabling it at the desired point with some minimal changes. - New system state variable. This state variable tracks all of the different state processes that Grbl performs, i.e. cycle start, feed hold, homing, etc. This is mainly for making managing of these task easier and more clear. - Position lost state variable. Only when homing is enabled, Grbl will refuse to move until homing is completed and position is known. This is mainly for safety. Otherwise, it will let users fend for themselves. - Moved the default settings defines into config.h. The plan is to eventually create a set of config.h's for particular as-built machines to help users from doing it themselves. - Moved around misc defines into .h files. And lots of other little things.

v1.0 Beta Release. - Tons of new stuff in this release, which is fairly stable and well tested. However, much more is coming soon! - Real-time parking motion with safety door. When this compile option is enabled, an opened safety door will cause Grbl to automatically feed hold, retract, de-energize the spindle/coolant, and parks near Z max. After the door is closed and resume is commanded, this reverses and the program continues as if nothing happened. This is also highly configurable. See config.h for details. - New spindle max and min rpm ‘$’ settings! This has been requested often. Grbl will output 5V when commanded to turn on the spindle at its max rpm, and 0.02V with min rpm. The voltage and the rpm range are linear to each other. This should help users tweak their settings to get close to true rpm’s. - If the new max rpm ‘$’ setting is set = 0 or less than min rpm, the spindle speed PWM pin will act like a regular on/off spindle enable pin. On pin D11. - BEWARE: Your old EEPROM settings will be wiped! The new spindle rpm settings require a new settings version, so Grbl will automatically wipe and restore the EEPROM with the new defaults. - Control pin can now be inverted individually with a CONTROL_INVERT_MASK in the cpu_map header file. Not typical for users to need this, but handy to have. - Fixed bug when Grbl receive too many characters in a line and overflows. Previously it would respond with an error per overflow character and another acknowledge upon an EOL character. This broke the streaming protocol. Now fixed to only respond with an error after an EOL character. - Fixed a bug with the safety door during an ALARM mode. You now can’t home or unlock the axes until the safety door has been closed. This is for safety reasons (obviously.) - Tweaked some the Mega2560 cpu_map settings . Increased segment buffer size and fixed the spindle PWM settings to output at a higher PWM frequency. - Generalized the delay function used by G4 delay for use by parking motion. Allows non-blocking status reports and real-time control during re-energizing of the spindle and coolant. - Added spindle rpm max and min defaults to default.h files. - Added a new print float for rpm values.

void mc_parking_motion(float *parking_target, float feed_rate);
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

// Performs system reset. If in motion state, kills all motion and sets system alarm.
void mc_reset();
New alarm method. Re(re)organized status messages. - Installed a new 'alarm' method to centralize motion kills across alarm or reset events. Right now, this is controlled by system abort and hard limits. But, in the future, a g-code parser error may call this too as a safety feature. - Re(re)organized status messages to just print all errors, regardless from where it was called. This centralizes them into one place. - Misc messages method installed for any user feedback that is not a confirmation or error. Mainly so that there is a place to perform warnings and such. - New stuff installed and still made the flash size smaller by saving flash space from clearing out repeated '\r\n' pgmstrings. - Fixed a bug where hard limits message would print everytime a system abort was sent.
