Hello, during an overnight print my print failed. Upon homing to restart the print I noticed my right Z axis was grinding. I rechecked my config and everything looked correct. In an attempt to troubleshoot I attached driver 0 to a spare stepper I have and noticed it only goes in one direction whether or not I try to move it + or -. I mean to say it moves as if I pressed + whether I press + or -.
I've performed all the troubleshooting I can think of and I cannot identify or resolve the issue.
I've reinstalled firmware, done a full power cycle, upgraded to beta, and checked for loose/damaged/corroded wiring.
Here is the result of M122:
