PCNC 1100 Series 3 problem with Z axis not moving

Came into the shop with the spindle all the way down. Couldn’t jog it back up in Z, although it showed it moving in the Z DRO. Shut it down and restarted. When jogging or homing it shows it moving in the Z DRO but won’t move physically. Any thoughts?

sounds like your ball screw is broke

same symptoms for me, twice - only on X

You should reach out to support. There are a number of things that can cause this

This. Could just be the coupler slipping or the brake not disconnecting or whatever. Need a lot more info to diagnose and support will be the best at that.

Just an update. Troubleshot some more. Turns out to be the Z axis driver, after 10+ years decided it was done.
