(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.
