If you want to learn how to convert your 3D printer to Klipper firmware, I have two examples to assist you step by step. In this video, I convert the FLsun Super Racer, a 32 bit delta printer with Octoprint. In a sister video, I convert the CR-10 Max, an 8 bit i3 ‘bed slinger’ cartesian printer with a BLtouch using Fluidd.

Klipper offers precise and fast printing, especially when using input shaping, which modifies the stepper inputs to remove ringing during high speed printing. Both of these printers will benefit from this plus get the added bonus of having wireless control.

This and the sister video are structured exactly the same, with more or less the same timestamps. They are designed so you can switch and forth between the two to suit your hardware and software requirements. Future videos will cover printer LCD/touch interfaces, pressure advance and input shaping.

This video is already very long, so please use it as a foundation to explore the comprehensive Klipper docs and flesh out your configuration file.
