Introduction to the MINI firmware

This is the first public GitHub release of the firmware for the printer Original Prusa MINI. This is a brand new branch of a firmware tailored for the Buddy board MINI developed by Prusa Research. Compared to the previous firmware for MK2S/MK3S, which is based on the 8-bit architecture is this firmware 32-bit and using ARM STM32F407 chipset.

The firmware is utilizing Marlin 2.0 to handle motion planning with multiple tweaks to comply with the Prusa in-house developed technologies. The user interface, WebUI and other parts of the firmware are fully developed at Prusa Research.

The board is capable of running RTOS (Real-Time OS). Therefore there are several parallel threads:

  • Marlin 2 (motion planning)
  • LCD GUI (graphic interface)
  • Networking (LAN and Wi-Fi communication)
