The initial release of the XL firmware
This is the first public GitHub release of the firmware for the printer Original Prusa XL. The firmware is tailored for the XLBuddy board developed by Prusa Research. Some parts of the code are shared with the Buddy board used in the Original Prusa MINI+.
The XLBuddy board is responsible for controlling the entire system and communicates in real-time with the other parts of the printer like the print tool(s) and the modular heatbed. The firmware for all boards is distributed in one .bbf file and XL updates its components automatically during the firmware flashing procedure.
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 XL architecture in detail in the upcoming dev diary.
