Ph73na, this was a long time ago for me… but if memory server, mine was a problem with my 3D printing module. I believe I had a thermistor issue. I replaced it, and it started working normally. I would suggest trying to swap to a different head (CNC or laser). You could also switch to the other port on the controller.
There is this thread here that could also help:
As far as rolling back firmware goes, I really have no idea. I’ve never had to do it. That might be a question best reserved for support.
Sorry, I do not have a simple solution for you. Best of luck. Perhaps someone else can chime in with some insight…
