Hello
I have the same problem with my ucr201.

or right or both, dont use disable.

I have a video of how it malfunctions,

If you are here you'll soon find out there is a new version of UCCNC that solves about 5 years of issues.
I know because I did the same

Which version are you referring to? I downloaded one from the forum a few weeks ago but it still had (albeit less frequent) issues with unexpected axis movements.

v1.2117 solved it for me. I had the issue happening when the screen turned off and I pressed any button on the pendant.
Which version are you on and when does the issue occur?

I am also on 1.2117. The unexpected movements are better but not completely gone. So far it has only happened on my X axis since the update. Before it was happenings on all of XYZ. I'm questioning if it's some sort of electrical interference issue. Just out of curiosity, what are you using for a control board?

I use an AXBB-E.
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!
