WARNING: There are still some bugs to be worked out. Please use caution if you test this firmware. - Feed holds work much better, but there are still some failure conditions that need to be worked out. This is the being worked on currently and a fix is planned to be pushed next. - Homing cycle refactoring: Slight adjustment of the homing cycle to allow for limit pins to be shared by different axes, as long as the shared limit pins are not homed on the same cycle. Also, removed the LOCATE_CYCLE portion of the homing cycle configuration. It was redundant. - Limit pin sharing: (See above). To clear up one or two limit pins for other IO, limit pins can now be shared. For example, the Z-limit can be shared with either X or Y limit pins, because it’s on a separate homing cycle. Hard limit will still work exactly as before. - Spindle pin output fixed. The pins weren’t getting initialized correctly. - Fixed a cycle issue where streaming was working almost like a single block mode. This was caused by a problem with the spindle_run() and coolant_run() commands and issuing an unintended planner buffer sync. - Refactored the cycle_start, feed_hold, and other runtime routines into the runtime command module, where they should be handled here only. These were redundant. - Moved some function calls around into more appropriate source code modules. - Fixed the reporting of spindle state.
