I should be able to get linear rails on the side of the extruded frame and pick up the gantry sides. Might need to alter the power chain arrangement. LOL sorry about the electronics waffle. Crowbar just means as it gets hot it reduces the current to the motor so it doesn't burn out the chip in the event of overheat. That in turn means your stepper soon has insufficient current to make it step anymore and it then drags the Z axis around the work at whatever height (normally last down feed), could do with current sensing on each axis to deal with this. The machine has its own supply as I am running a 3 phase spindle, again the X-Controller interests me as they will provide a 0-10vdc out that can control the spindle speed controller.

My Heiz controller is one of the early models, not the newer metal cased jobs.
