General Mach Discussion / A axis stepper rotation error

« on: January 19, 2021, 02:41:48 PM »

Trying to use a axis for rotary scan.  I aligned X, Y axis to center of plate.  My A axis stepper is over rotating for a 360 degree program.  One full rotation of plate registers as ~300 degrees in controller.  The belts and gears are not slipping and there doesn't seem to be any tangible fault.
