Klipper

Klipper is the firmware and software responsible for running the 3D printer. It is different from traditional 3D printer firmware in that it has two components: a firmware that runs on the microcontroller of the BTT Octopus board, and a software that runs on a Raspberry Pi computer. With most firmwares, such as Marlin, g-code instructions are sent directly to the microcontroller, which are then processed into stepper motor movement commands. With Klipper, this processing is done on the much more powerful Raspberry Pi, which then sends the stepper motor commands to the microcontroller which executes them.

Klipper is configured to use Mainsail as its web interface

Configuration File

Klipper's configuration file is as follows as of 2/20/2025:

klipper.cfg 




Configuration Template


The Octopus board comes with a configuration file template for an Octopus v1.1 / Voron 2.4 / Klipper combo design. This can be found here. Only use as a general guide because it does not exactly match our printer setup.


Useful Klipper Features


The greater computing power of the Raspberry Pi allows many more printer features to be implemented, such as input shaping. Below are some references for Klipper features that could be useful:
