The machine came with a bad z-stepper so I had to buy a replacment. The replacement didnt allow me to use the aluminum knob so I had to modify the replacement. The replacement motor didnt work with my machines. I dont know if the stator winding were different, but it wouldnt run. Also, the replacement lead screw has the wrong pitch as well. I purchaseld another replacement to replace the replacement. LOL. Awesome solid machine. Weighs about 16lbs. The UV green back mounting plate is custom. Also, the power supply I'm using is an after market 24v 5A supply.
