The previous owner of this Torq-Cut 22 that I recently purchased told me that they were having problems with rapid movements in the Z axis. When the machine rapids in Z, I get a "Z Axis Drive Over Current Fault". What they advised as the work-around was to change all G00 moves to G01 movements at 40 IPM. Did it and it works. I would still like to fix the root cause. Any advise?
