I had to cut out the old lead nut and drill tiny holes to mount it. The wiring that came with the new motor plugged into the main board but the motor turned the wrong way so I had to switch two wires. Do not switch them the way they did it in the guide it will not work.

Something to consider is also that the stock screw is not standard and you should change your layer height to

Layer Height (mm) 0.04375 (results may vary)* 0.0875 0.13125 0.175 0.21875 0.2625 0.30625
