DISASSEMBLING AN EXTRUDER
1. Unload the MakerBot Filament from the
extruder. To run the script for unloading
filament, go to the LCD panel and select
Utilities > Filament Options > Unload.
2. Switch off the power on the MakerBot
Replicator 2X and unplug the power supply.
Pull on the connector to release it from the
power input port.
3. Unscrew the two bolts at the lower
corners of the fan guard using your
2.5 mm hex wrench. As one piece, remove
the fan guard, the fan, the heat sink, and the
spacers. Keep these pieces assembled and
move them out of the way.
4. Set the extruder lever arm to the open
position. [Fig 1.2]
5. Unplug the motor wire harness from the
top of the extruder motor and slide the
motor assembly out of the extruder.
6. The extruder is now broken down into its
main assemblies. [Fig 1.3] To remove any
filament stuck in the thermal barrier tube,
turn on the Replicator 2X, run the Unload
script to heat the extruder and use a pair of
pliers to pull the filament free.
