3D Printer Extrusion Stops

There are a few problems that can cause your MakerBot Replicator 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 shaft that is visible at the back of the motor.
When the extruder is running, you should be able to see the shaft turning.
The shaft may sometimes reverse direction in order to retract filament, but during extrusion it should be moving at a slow but constant rate.
If the shaft does not turn, or stops turning, please contact us.

• 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 left.
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.
