Klipper - use Raspberry Pi to offload calculations from 3D printer mainboard


Klipper is a special firmware designed to perform the heavy lifting of kinematics on a Raspberry Pi and simplify the job of the existing 3D printer mainboard. This allows very precise stepper motor timing and potentially much higher speeds.

Works with Octoprint. This allows the printer to be controlled using a regular web-browser. The same Raspberry Pi that runs Klipper can also run Octoprint.

In this video, a step by step guide to installing and configuring Klipper on an Ender 3. It includes the base set up as well as how to get a BLtouch and pressure advance working.

In the next part, I will tackle other boards and stepper motor drivers, including a Klipper specific board called the Printhat from Wrecklabs. I have tried to be as comprehensive as I can in this video but there is a lot to cover. Please read carefully through the docs I have referenced below.
