Y Axis not moving

[billh 0]

My Y Axis is not moving, just making noise.

I followed the following steps to try to isolate the problem;

1) I loosened the motor mounting screws so that the motor was loose on the belt and tried to jog it with Cura to eliminate the pulleys, belts bearings and squareness from the motor.

2) I switched the X and Y Axis plugs on the board and still had the problem with Y motor driven by the X axis.

3) I want to adjust the pot for the Y Axis but it is so tiny that I can't tell which screwdriver bit is correct or even if I am engaging a screw. I tried to see it better with a magnifying app but that still didn't help because it is so tiny and reflective. The pots do not match the pots in the wiki or any pot I have adjusted in the past.

Any suggestions are most welcome!

Thanks, Bill

If you swapped the motors cables around did the problem swap with the motor? If that's the case then you could have a cabling problem in your Y motor.

Daid,

Thanks for the quick reply and for Cura!.

Any suggestions to isolate the motor wiring as a root cause?

Yes. Swapping just the motor cable from the X and Y connector (so X drivers moves the Y motor) and then test the motor, if the problem stays with the motor then the motor or motor wiring is the problem, else it's the driver, electronics or the Arduino.
