Tools
You will need the following tools
- M3 Allen key
- Long-nosed pliers
- Tweezers
Step 1: Z Coupling
| |
| Item | Quantity |
| Nema 17 Motor | 2 |
| Printed coupling | 4 |
| 215mm M5 Studding | 2 |
| 30mm 5mm Diameter tubing | 2 |
| M3 Washer | 8 |
| M3 Nut | 4 |
| M3x20mm cap screws | 4 |
| M3x10mm cap screws | 4 |
Start by fitting the couplings to the Z Motor. Begin by inserting hal tubing ovf of the tubing over the motor shaft. Next take one of the printed couplings and clip is over the motor side of the tubing as shown.. Ensure that the gap in the coupling is aligned with the flat of the motor shaft. Then insert one of the M3 X 20mm cap screws and a washer into the hole in the coupling, and secure with a nut on the other side. Repeat this setup on the free side of the tubing; however leave the clamps on the free side loose.
Repeat this setup for the second Nema 17, and mount each of these motors to the Z motor mounts at the top of the frame using the 2x M3x10mm cap screws and washers on each.
