I am using a Sainsmart 3018 Prover. Got it new a few weeks ago. (wore out the first one - LOL)
Yesterday it started to “chirp” and seemed to be skipping. While looking at the travel bar ( a technical term, I’m sure ) it came off the right side stepper motor.
I cleaned it, loosened the set screws, reseated it and tightened the set screws.
It was fine for part of the 1st job I ran and then started chirping again.
Travel bar is still seated tightly.
What else should I be looking for?
Thank you in advance for your help.
