Hard limits, homing direction, pull-off limits after homing, status reports in mm or inches, system alarm, and more.
- Thank you statement added for Alden Hart of Synthetos. - Hard limits option added, which also works with homing by pulling off the switches to help prevent unintended triggering. Hard limits use a interrupt to sense a falling edge pin change and immediately go into alarm mode, which stops everything and forces the user to issue a reset (Ctrl-x) or reboot. - Auto cycle start now a configuration option. - Alarm mode: A new method to kill all Grbl processes in the event of something catastrophic or potentially catastropic. Just works with hard limits for now, but will be expanded to include g-code errors (most likely) and other events. - Updated status reports to be configurable in inches or mm mode. Much more to do here, but this is the first step. - New settings: auto cycle start, hard limit enable, homing direction mask (which works the same as the stepper mask), homing pulloff distance (or distance traveled from homed machine zero to prevent accidental limit trip). - Minor memory liberation and calculation speed ups.
