Common Issue Descriptions:
Connect the rotary module directly to the Motion 1 port on the main controller without using the extension cord and check if the issue persists.
If you have a Snapmaker 2.0 machine, try connecting the rotary module to it and see if the same issue occurs.
If both the extension cable and the rotary module are functioning properly, the problem is likely due to a faulty main controller board.
