I just bought a CNCEST 3040T 4 Axis CNC machine with the VFD 800w motor.

Set it all up and all of a sudden the Z drive stopped working after initially working. I swapped the Y and Z on the back of the controller and the Z drive works under the Y axis so it is not the stepper motor of the Z axis

I've uninstalled MACH 3, removed the MACH 3 folder and re-installed but still the Z drive does not function.

While I await the seller to contact regarding the issue I'm pondering fixing this and making it better at the same time rather than a return.

Anyone have any ideas what the issue could be?
