Adapter Plate Replacement

The two adapter plates or “blocks” will only require replacement in the event of an

undetected machining error, i.e. holes drilled too deeply, resulting in a weakened mount

to the belt coupling. The detailed instructions below cover the top X-axis adapter plate.

Steps 1 – 4 are identical to the above belt replacement procedure.

1) Turn off power to the machine, and move the gantry to the right to the approximate

center of the frame.

2) Mount an angle bracket on each side of both X-axis bearing carts using spring-

loaded T-nuts and flat head M5 bolts. (5mm Allen wrench) Make sure that the gantry

is completely locked in place with the four brackets.

3) Remove the two 3/8” nuts from the underside of the X-axis cable carrier bracket. Pull

the cables upward to remove the small bolts from the bracket.

4) Remove the two screws from the cable carrier bracket, and remove it from the

adapter block.

5) Remove the bolt

mounting the belt

coupling to the lower left

hole in the adapter

block. (5mm Allen

wrench)
