TROUBLESHOOTING
SOLUTION
In the print monitor panel of MakerBot Desktop,
click Change, and then select Load Filament.
Let the filament extrude for a few seconds, then
click Done and Unload Filament to try
unloading again.
Make sure to wait to remove the filament until
MakerBot Desktop has instructed you to do
so. If you still cannot remove the filament, try
squeezing the tabs on the side of the Smart
Extruder and pulling on the filament.
Ensure that the filament unwinds counterclockwise
from the spool. Always unload any filament left
in the Smart Extruder before reloading. Make
sure the filament guide tube is secured to the
filament spool pocket.
Try unloading and then reloading the filament.
Repeat this process a few times if necessary.
You may be able to avoid jams in the future by
allowing the Smart Extruder to cool to 50° C
before removing the Smart Extruder or turning
off your MakerBot Replicator Mini.
