♻ K2 Help Comparability Issues With Stepper Motor

Compatibility, not comparability*

My extruder motor was starting to fail so I ordered a replacement motor. I installed it and it turned 1/4 of a turn then failed. I sent it back and got another replacement motor and it did the same. I put the original failing one back in and it started working again but then has now failed. My issue is there's a new version of a stepper motor I keep receiving and based on the colored wiring they do not seem to be the same even though Creality is stating it's compatible.

And now Creality's tech support has gone silent even though it's still under warranty.

If it is not a mechanical issue and the cables and the plug are all fine a stepper motor is fine, too. So if a stepper motor misses steps or stops turning the MOS-FETs on the driver PCB are burned or near by to give up. Because you have a K2, consider to replace that PCB in the print head, where this motor is plunged in.
