An advanced FDM 3D Printer Firmware
"Klipper is a 3d-Printer firmware. It combines the power of a general purpose computer with one or more micro-controllers." (The Project's Website)

Hardware

1.) A Single Board Computer (or in theory at least a used low-spec computer acquired for cheap?)
- Typically:
  - A Raspberry Pi Zero if not utilizing 3D Printer Webcam functionalities
  - A Raspberry Pi (need to grab what model is recommended, 2/3/4 etc) if utilizing the camera and/or other more intensive features
2.) A Standard Control Board (This no longer does the calculations of G Code to various electronics as this is offloaded to the Raspberry Pi)
(Optional) 3.) A Klipperscreen ( Raspberry Pi Touchscreen + (Most Likely 3D Printed) Enclosure + Wiring )
