Motor trouble

[Raimond]

I agree that these problems need to be documented and saved for those in the future having similar problems. They can find the answer much quicker than we did.

Here is the adjustment I made to the XY speed, that started the issues I was having.

I tried to print ABS and started having problems again. The only thing that changed was the temps. More detailed troubleshooting and I found two of the motor wires to have an intermittent break. While it was printing I could move the wires and cause it to start skipping. Release them and it would stop. Removed about a 4" section in both wires about 2" from the motor connector, and it is again working without issue. I added a section of heat shrink tubing at the connector and then changed the layout of the wires and let them hang down from the motor with a loop back up to the top support. I then put a section of plastic split loom covering on it. Much less flexing of the wire harness now.
