Axial Thrust Bearing

The axial thrust bearing has three components. Two end caps and an inner bearing assembly.

pillow_block printed part

Assemble the axial thrust bearing into the pillow_block as shown

Make sure that the thrust bearing is fully inserted into the printed part. The top ring of the thrust bearing should be flush with the top of the pillow_block.

If desired, you may add a drop of light oil to the inner bearing assembly of the thrust bearing

lead_screw_motor_cage_front_3.1 printed part

Place the pillow_block assembly atop the lead_screw_motor_cage_front_3.1 in preparation for the next step

M3x18 Cap Head Screw

48mm NEMA17 Stepper Motor

Insert the NEMA17 motor into the lead_screw_motor_cage printed part, as shown

Insert each M3x18 cap head screw through the pillow block, the lead screw motor cage, and fasten them into the NEMA17 motor

Take care not to over tighten the M3x18 screws as you can damage the printed parts

Assembly from the previous step

Rigid Lead Screw Coupler

Install the lead screw coupler on to the exposed shaft of the NEMA17 motor

Apply downward pressure to the top of the lead screw coupler whilst tightening the marked screw

Tighten the marked M3 screw to secure the lead screw coupler to the motor shaft

M6x20 Cap Head Screw

Insert each M6x20 cap head screw into the lead screw motor mount as shown

3030 Drop-in T-Nut - M6

Loosely thread a 3030 T-Nut onto each of the M6x20 screws. Do not tighten them at this point.

M3 Nylon Locking Hex Nut

Insert an M3 nut into each marked position

Do not worry about fully seating the M3 nuts into the mount, this will be done in the next step

M3x12 Cap Head Screw

Insert each M3x12 cap head screw into the lead screw motor mount as shown

Slowly tighten the each screw to seat the M3 nut below

Take care not to over tighten the M3x12 screws as you can damage the printed part

These screws are used to mount the optional printed trim part when using a base panel

Repeat Steps 3 to 8 to assemble the right Z-axis motor mount

Once you have both front Z-axis motor mounts assembled as shown, proceed to the next step
