10) Remove the four bolts
from the rear of the
bearing cart adapter
block, using a 5mm Allen
wrench. Do NOT loosen
or remove the single bolt
which mounts the block to
the X-axis belt coupling.
11) Strongly suggested: Loosen all four Y-axis motor mounting bolts/nuts (5/32” Allen
wrench and 3/8” wrench), and remove the Y-axis motor belt. Remove the motor
mount bolts entirely, and remove the Y-motor and pulley from the mounting plate.
This step helps to significantly reduce the weight of the top of the gantry, and
decreases the chance of the gantry being forced out of square. (see Motor
Replacement procedure)
12) From the front of the
machine, pry away the two
yellow plastic strips from
the top of the Y-gantry, in
order to access the two
large bolts underneath.
Remove both of the bolts
with a 6mm Allen wrench.
