13) Carefully slide the top X-axis
bearing cart and standoff block
off to the right, and completely
off the upper rail extrusion. Be
careful not to bump or disturb
the top end of the gantry while
the bearing cart is removed.
14) Note the location and
orientation of the standoff
block on the bearing cart.
Loosen and remove the two
recessed bolts with a 5mm
Allen wrench, and remove the
standoff block from the
bearing cart. Note: Keep both
of the black plastic end caps
snapped onto the standoff
black – this will keep the T-
nuts from falling out.
