Figure 6-18. Push the filament into the extruder
Watch the nozzle of the extruder. When you see the MakerBot PLA Filament
that you loaded come out of the nozzle, press the M button to stop extrusion.
Don't be surprised if the filament that initially comes out of the nozzle is not
the color you expected. There's probably still some filament inside the ex-
truder left over from our testing process at the MakerBot BotCave. Wait until
you see the the MakerBot PLA Filament that you loaded come out of the
nozzle before you press the M button.
Now, push the guide tube back into the opening on the top of the extruder
( Figure 6-19 ).
