Asssembly
From Geeetech Wiki
1. Check that you have everything that's needed
2. Twist the two motor wires together so they are easier to handle (and electromagnetic noise is reduced)
3. Thread the twisted motor wires through the motor mount arm section. It can be a bit tricky so have patience.
4. Insert the motor into the motor mount and be careful to not damage the motor wires while inserting it.
5. Press the motor mount on to the PCB arm. Be careful not to damage the wires when you do it. Start with M1.
