Looking for some clues where to start troubleshooting my 8" 4th axis. Was running a job and the table wouldn't rotate. Had been running for an hour with no issues. Was just moving the rotary through the mdi, g1 a72, etc. Wasn't running any g code routine, so its not locked up from a goofy code.
Pulled the stepper and tried to move it with the jog shuttle. It responds "a little ", maybe advances one step, but then bounces back to the original position.
Any ideas where to start would be greatly appreciated!
