3D Printer - Bootstrapping the extruder

Last time, I mentioned that the extruder filament drive assembly was itself 3D printed on the converted CNC machine. How is this done without purchasing an off-the-shelf extruder filament drive assembly? In short, I used the CNC machine in its pre-converted state to create the first version of the filament drive.

3D Printer - The Temperature Controller

Before I say anything about converting my gantry CNC milling machine to do 3D printing, I figured I'd cover the controller I designed and built for the extruder and heated bed. Unlike most purpose built 3D printers, like one built from user-sourced parts, a kit, or even a pre-built unit, a CNC milling machine doesn't provide for controlling the temperature of the extruder nozzle and the heated build bed. This project describe that part of the conversion process.
