MakerBot Replicator 2X, Troubleshooting And Maintenance

Page: 34 / 40

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 you
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 MakerBot Replicator 2X upper frame.
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.

5. Manually move the extruders to the
front of the MakerBot Replicator 2X, as far
forward as they will go. Make sure that the
plastic pieces on both sides of the gantry
are flush against the plastic brackets that
hold the two front pulleys.
