Bed Leveling and Z axes misalignment

This one is a little weird. I was able to complete a few prints, when suddenly my Z access developed an issue. It was literally right after I'd completed a fairly simple print for my brother. What appears to be happening is that the two Z axis motors are turning at different rates. I'll see the Zright bracket move up and down, but the Zleft bracket won't move or moves significantly less. This makes the X axes rider bar unleveled and the printer works to return everything to the position it was just in. This is while I'm attempting to do self tests and the like. The interesting part is that the Zleft axes seems to work fine when trying to get to home, it just can't continue with the test. Is it possible I need to lubricate a part? Loosen a binding? It was working fine until suddenly it wasn't. There was a crash detected, but the system returned home without issue afterwards.

RE: Bed Leveling and Z axes misalignment

If you are sure it is not mechanical, i.e, the cable binding on something or the Zaxis screw thread  not have anything on it stopping the left Z bracket from moving, then it maybe electrical. Wiring to the Zleft may have a problem. Either a loose wire or broken wire. Of course as you say the motor may have a problem.

Loose electrical connection for the Zleft axes. Not sure how it was functioning for so long, or how it got knocked loose. It passes the self test. Thanks for the help.
