EShapeoko 1.3 Assembly: Z motor
You need all the parts from Pack 9, and the motor plate assembly from the previous step.
Put the flexible coupler on the motor shaft, but do not tighten it yet.
Use the three long M3 screws to attach the motor to the Z motor plate, on the same side as the bearing. Use one longer and one shorter spacer on each screw. Use the three holes at the corners of the plate; do not use the hole near the larger oval holes.
Put a washer on each screw. Insert them through the three holes in the corners of the plate, from the side opposite the bearing. Put one longer and one shorter spacer on each screw. Offer the motor. Put a washer and a nut on each screw. Tighten, holding the nuts with an open-ended 8 mm spanner.
