Part 5 is packed with serious upgrades and creative 3D prints. The build volume is enclosed with plasma cut sheet metal, CNC milled components, and topped with a massive ABS hat – 3D printed of course! Inevitably there were some issues and expensive mishaps as Dr. D-Flo attempted to print with ABS pellets, a material notorious for warping. But active chamber heating, a new pellet vibrator upgrade, closed-loop stepper motors, and CAN expansion boards vastly increased the reliability of this printer.
