¶ Step 2 - Attach Z Plates
- Low Profile Screw M5x12mm

- Bottom Z Plate. Do not fasten all the way down yet, you will need some room for adjustment.
- Carefully align the Top Z Plate with the corners of the C-Beam before tightening down the screws.
¶ Step 3 - A note about Flexible Couplings
- Flexible couplings allow you to connect 2 rods with different diameters while providing some flexibility at the joint.
- Smaller diameter rod is inserted here
- Larger diameter rod is inserted here
- These larger screws act like a clamp on the entire coupling. Tighten these first.
- These set screws press directly against the tip of each rod, locking it in place.
¶ Step 4 - Mount Z Motor
- Flexible Coupling 1/4''x8mm
- Spacer 40mm
- Nema 23 Motor
- Cap Head Screw M5x50mm
¶ Step 5 - Mount Z Lead Screw
- Lead Screw 281mm
- 688ZZ Ball Bearing
- Precision Shim 12x8x1mm
- Lock Collar 8mm
- Attach the 8mm end of the flexible coupling to the lead screw. On the coupling, tighten the clamping screws first, and the set screw afterwards.
- Fully tighten the screws on the Bottom Z Plate, which you left slightly loose on step 2.
- Press the Lock Collars against the inner face of each Z Plate, and tighten their Set Screw, to lock them in position.
¶ Step 6 - Set up Angle Corners (x4)
- Repeat this step for 4 Angle Corners
- Button Head Screw M5x8mm
