The Filament Feeding Mechanism
Now that your Extruder is complete, it's time to bolt it onto your 3D printer frame. Your 3D printer works
by feeding a plastic filament into the heater core of the Extruder. The plastic melts and is then forced
through the Extruder's nozzle and applied to the worktable to print three dimensional objects.
You've still got some electronics to handle (all those little circuit boards that actually allow the
machine to work) but you'll deal with those parts in the next chapter. This chapter will be short and
sweet; you're going to connect the Extruder and the last stepper motor to the machine.
