LOADING MAKERBOT PLA FILAMENT CONTINUED
Free the end of the MakerBot PLA Filament 
from the filament spool. With a pair of 
scissors, cut a clean edge. Feed the end of 
the MakerBot PLA Filament into the end 
of the guide tube where it attaches to the 
back of the MakerBot Replicator 2. Feed the 
MakerBot PLA Filament through the guide 
tube until it emerges from the other end of 
the tube.
NOTE: To avoid filament jams, ensure that the 
MakerBot PLA Filament feeds from the bottom of 
the spool toward the top of the spool. Ensure that 
the MakerBot PLA Filament is mounted on the le 
spool holder when viewed from the back and that 
it unspools counter-clockwise.
