Realigning The Gantry - MakerBot Replicator 2X User Manual

REALIGNING THE GANTRY

The gantry is the system of rods and belts that moves the extruder. If one side is
too far out of alignment with the other, the outlines of printed objects might appear
slanted on the build plate. You should make sure your gantry is aligned after moving or
jolting your MakerBot Replicator 2X.
To determine whether your gantry is aligned correctly, push the extruders all the way to the
front of the MakerBot Replicator 2X. Hold the right side of the gantry against the front of
the MakerBot Replicator 2X. Then try pushing the left side forwards. It should not move. If it
does move, perform the following steps.
1. Turn off the MakerBot Replicator 2X.
2. Unscrew the bolts on each of the MakerBot Replicator 2X side panels. Set the bolts and
panels aside.
3. Locate the four pulleys holding the Y-axis belts. There is one pulley in each corner of
the upper frame of the MakerBot Replicator 2X. You will see two pulleys in the back
right corner of the MakerBot Replicator 2X. You will be adjusting the pulley closer to the
center of the MakerBot Replicator 2X.
4. For each pulley, manually move the extruders backwards or forwards to rotate the
pulley until you have a clear view of the set screw holding the pulley to the front or
back gantry rod. Use the 1.5 mm hex wrench from the accessory box to loosen each
set screw.
