- 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.
