The official open-source firmware for Prusa Research 3D printers (MINI, MK3.5/MK3.9/MK4, XL, CORE One) running on 32-bit ARM microcontrollers. It is a C/C++ codebase built with CMake and a Python build wrapper, with regular releases.
Use cases
- update the firmware on my Prusa MK4
- build custom firmware for the Prusa MINI
- contribute features or bug fixes to Prusa printer firmware
- flash a beta firmware release on my Prusa XL
- customize printer behavior on the Buddy board
- debug firmware issues on a Prusa CORE One
When to choose
- you own a supported Prusa printer and want official or customized firmware
- you want to contribute to or fork Prusa's printer firmware
- you need to build firmware images for the Buddy board from source
When to avoid
- you use third-party or non-Prusa 3D printers
- you need Marlin or Klipper-style firmware for other boards
- you only want slicing or printer control software rather than device firmware
