The initial release of the MK4 firmware
This is the first public GitHub release of the firmware for the printer Original Prusa MK4. The firmware is tailored for the xBuddy board developed by Prusa Research. Some parts of the code are shared with the Buddy board used in the Original Prusa MINI+ and the XLBuddy board used in the XL.
The xBuddy board is responsible for controlling the entire system and communicates in real-time with the other parts of the printer like the Nextruder.
The firmware is utilizing Marlin 2.0 to handle motion planning with significant changes to comply with the Prusa in-house developed technologies. The user interface, WebUI and other firmware parts have been fully developed at Prusa Research.
We will describe the entire MK4 architecture in detail in the upcoming dev diary.
