Hello I have an IH CNC mill that just started having an issue with Z axis. I started out as a z axis fault so I hit the reset on my machine. ( I have a reset button for each drive built into my control box ) So once I disengage the E ZStop button and reset each drive the Z axis wants to rapid to the moon. I have to press the E Stop button before it crashes into my limit switch.

What could be the issue here?

I have disconnected and reconnected the wires for all Z Axis to assure proper connection and still same thing,





Any and all help would be greatly appreciated !

Thanks
