1 out of 2 Z axis motor not working

Troubleshooting

Hey everyone. In the ever growing flaws in this machine, is there reason why only one z axis would work and not the other? I was barely able to get a complete calibration cycle yesterday. I turned the machine on today to try to cut something and only one stepper motor on the z axis turns. The machine wasn’t touched until this bootup so I don’t know what’s the issue at this point? Any ideas?

There are two common causes.

  1. the motors aren’t quite aligned, losen the bolts holding them and see if that
    works.

  2. there was a batch of boards that had one chip not soldered down correctly.
    @bar is replacing the boards as people run into grief. Switch the Z motors and
    if the problem moves to the other motor, contact @bar and he will send you a
    coupon code to order a replacement board
