prs stnd z axis motor stops....

[Ron Barnes]

Out of nowhere the other day my z axis motor stopped running and I could not get it moving again, I did swap out the cables from the y axis to the z and vise versa and she worked fine then upon reconnecting the correct lines to the asix's all work well. THEN later the same day and the following day it did the same thing...Anyone have an idea what's happening? I was thinking my 2gb usb port but it's not very old.

I would do a real close look at the connectors.

The usb will cause you to loose everything, but not just one axis. It has to be something related to that one motor only. Could be a driver, motor, cable, connector,ect...

Keep swapping parts till the problem moves and you are there.

I had the same issue with one of my X motors and it turned out to be a bad controller. If you cycle the power off and back on it would work again but it would drop out every so often and not consistent it took me over a year to find the problem but since changing the control box it has been flawless for several years.
