18) Slide the bearing cart and block behind the top end of the gantry, and align the T-
nuts with the holes in the gantry beam. Insert the mounting bolts through the beam,
and tighten them both securely with a 6mm Allen wrench.
19) Slide the top end of the Y-axis cable carrier channel back into alignment with the
standoff block, and tighten the 5mm bolt when the channel is parallel to the gantry
beam. Replace the cable tie at the top of the gantry and secure the rear cables into
position.
20) Go to the rear of the machine, and replace the four bolts into the adapter block.
Tighten all 4 securely.
21) Mount the cable carrier bracket to the rear of the adapter block with the two screws
(5/32” Allen wrench) Mount the cable chain onto the carrier bracket, and tighten the
two nuts underneath.
22) Mount the Y-axis motor back onto the motor mounting plate, and tighten the four
mounting bolts most of the way. Replace the motor belt, apply the proper tension,
and tighten the mounting bolts securely. (See Motor Belt Replacement procedure)
23) Replace the two bolts and nylon spacer-bushings through the top cable plate. Make
sure to mount the Y-axis motor cable bracket to the bolt that is towards the rear.
Plug the motor cable back into the socket, and turn the locking collar clockwise until
you feel a slight detent.
24) Replace the top right bumper bracket to the top extrusion, making sure to align it
with the pencil marks you traced onto the frame.
25) Replace the torque rod housing onto the right side of the machine: 5mm Allen bolt,
5/16” hex screw, then Philips screw. Make sure that the black rubber anti-vibration
strip is in place along the entire length of the housing.
26) Replace the Y-motor housing. (four 5/16” hex screws)
27) Remove the two angle brackets from the lower frame extrusion on either side of the
bearing cart. Remove the T-nuts from the slot in the extrusion to prevent possible
jamming with the bearing cart during cutting.
