Adjusting the Plunger
After 100 or more hours of printing, you might need to adjust the plunger in the extruder
assembly. The plunger pushes the MakerBot PLA Filament against the drive gear. If the
plunger wears down and is no longer putting pressure on the MakerBot PLA Filament, the
MakerBot Replicator 2 may stop extruding. You can solve this problem by making a small
adjustment to the plunger.
1. Unbolt the active cooling fan. The active
cooling fan is located on the left side of
the extruder. Use the 2.5mm hex wrench
included with your Replicator 2 to remove
the two bolts that attach the active cooling
fan to the extruder.
