TROUBLESHOOTING

EXTRUSION STOPS

There are a few problems that can cause your MakerBot Replicator 2X to stop

extruding. Use this checklist to determine the cause and appropriate solution.

• Is your extruder motor rotating? Use a marker to draw a line across the end of the

motor sha that is visible at the back of the motor. When the extruder is running, you

should be able to see the sha turning. The sha may sometimes reverse direction

in order to retract ﬁlament, but during extrusion it should be moving at a slow but

constant rate. If the sha does not turn, or stops turning, please visit makerbot.com/

support/new/support to learn what your support options are.

• Is your ﬁlament tangled? Check that the spool is spinning smoothly on the mount.

• Is the build plate too close to the extruder? If so, there might not be room for the

plastic to come out of the extruder. If your extruder stops extruding during the first

or second layer of a build, this usually indicates that the build plate is too close to

the extruder.

• Is the nozzle clogged? Go to the LCD menu on your MakerBot Replicator 2X and

navigate to Utilities > Change Filament > Load right or Load le. Run the Load

script. Observe the plastic as it emerges from the nozzle. Does it drop straight down,

or curl up toward the extruder? If it curls back up toward the extruder, the nozzle may

be partially clogged. See the section Filament Stuck on page 71 for more help.
