LOADING MAKERBOT PLA FILAMENT 
When you have completed the initial leveling tasks, the LCD menu will display the following 
text: “Aaah, that feels much better. Let’s go on and load some plastic!” Before building, 
you must load the MakerBot PLA Filament into the extruder. The extruder will heat the 
MakerBot PLA Filament and use the melted material to build things.
What You Will Do
• Remove the end of the 
filament guide tube from 
the hole in the top of 
the extruder.
• Feed the free end of the 
MakerBot PLA Filament 
from the spool into the 
end of the filament guide 
tube where it attaches to 
the back of the MakerBot 
Replicator 2.
• Push the MakerBot  
PLA Filament all the  
way through the  
filament guide tube.
• Insert the free end of the 
MakerBot PLA Filament 
into the hole in the top of 
the extruder.
• Wait for the MakerBot 
PLA Filament to heat 
and extrude.
• Return the filament guide 
tube to the hole in the top 
of the extruder.
