MACH3 - Spindle set as Axis 5 (C)
Encoder feedback connected to HiCON A/A+ B/B+ Z/Z+ Verified with scope it is receiving a good signal.
Encoder feedback is displayed in Encoder 1 with Axis C set to feedback on Encoder 5
Have tried all home setting combinations, behaves same if set to sensor or index only with or without use index checked.
Have tried setting C home in Mach to the actual HiCON pin 13/3 or a phantom MACH pin.
PROBLEM: C axis will not home
PROBLEM: As soon as spindle is shut off, C axis DROs go to zero, so spindle positioning for ATC is not possible.
What is the proper config to have the spindle stop at the same spot each time?
