Ok this is a bit of a strange one.....
I have 2 screws for an axis. They move independently using the pendant in both directions but when using Mach3 to jog the axis using the keyboard something odd happens!
At this point i haven't slaved the 2 sides together. A side of the axis moves up and down fine. B side moves up only. When i try to jog side B down it seems to release the holding voltage and spins free.
I have to tap the key to jog side A down slightly and then side B will jog down.
Side B then moves in both directions but side A will only move the 1 way.
Has anyone else had experience on this?
