K1C is losing position and crashing on boundary

I caught it in action in a video. After finishing a layer it fails an XY jog and then seems to lose position. It starts the next layer in the failed jog position and then runs into the boundary but tries to keep going. Makes a lot of noise and even runs in to the tip cleaner.

This happens with a different model that I tried as well. It’s been running great with no issues for several weeks…now this all of a sudden.

It also makes a squeaking sound if the XY slides…even by hand. Seems to come from motor area.

I suspect a slipping pulley on a motor shaft or binding axis. Any ideas? Amazon return period ends in 5 days…
