Adjusting the Plunger

If you are having trouble building things, 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 is putting too much or too little pressure on the MakerBot PLA Filament, the

MakerBot Replicator 2 may stop extruding. If you hear a faint clicking noise coming from

your extruder, the plunger is exerting too much pressure. If you can stop the ﬁlament from

feeding by squeezing it between your ﬁngers, the plunger is exerting too little pressure. You

can solve both of these problems by making small adjustments to the plunger.

For more details on adjusting the plunger, get in touch with MakerBot support by emailing

support@makerbot.com or see the MakerBot Support website at makerbot.com/support/

replicator2/troubleshooting.

1. Remove the active cooling fan. The active

cooling fan is located on the le side of the

extruder. Use a Phillips head screwdriver

to remove the two screws that attach the

active cooling fan to the extruder.

NOTE: When you remove the active cooling fan

you will expose some of the extruder wires. Be

careful of these wires when adjusting the plunger

and reattaching the active cooling fan.
