MAINTENANCE

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 le side forwards. It should not move. If it

does move, perform the following steps.

1. Turn o 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.
