Do you have any buttons or another handwheel/keypad connected to the board?
The AXBB-E did give me false inputs, triggering the limit switches, and the signal debounce feature solved the issue.
I don't knowingly have anything else wired in for direction or step signalling, but now I've got to go take a closer look on the chance one of the defaults had something setup for this. I'm running using a UC400ETH so for now at least I'll assume it's not as likely to be a hardware issue.
I was thinking it could be some feedback from a VFD but sometimes these movements happen when there is no active VFD.
The hunt continues!
