Seems like an axis is skipping steps. Check all belts for the correct tension, all pulleys (Can come loose over time), wiring to the motors and bearings. The axis should move smoothly, and can be verified by unscrewing the pulley that’s on the motor (So that does not interfere with mechanical drag).

I have a CTC replicator duel, but I scrapped the electronics and gantry that came with it.

I’ve been having the same problem for some weeks now. What did you find to be the problem on yours.

Hi yeah the pulley had come loose , I replaced with all metal pulleys , the pulley is s2m 17 teeth pulley for a ctc , I couldn’t find anywhere except eBay shop called tinlydscreations
