Rear bed arm assembly

380mm TR8x4 Lead Screw

Install the lead screw through the rear bed arm and decoupler

Do not force the lead screw through the POM nut on the decoupler as this can cause damage. It should thread through smoothly

Rigid Lead Screw Coupler

Continue threading the lead screw through the arm until it reaches the rigid lead screw coupler on the rear Z-axis motor mount

Insert the lead screw fully into the rigid coupler

Fasten the marked M3 screw to secure the lead screw to the NEMA17 motor
