Configuring Prusa All-in-One Firmware

To configure this firmware, enable options in Prusa_AIO_Configuration.h. No other config file editing is required!

Building Prusa All-in-One Firmware

To build this firmware, you'll need Visual Studio Code with PlatformIO. Detailed setup instructions can be found in the Installing Marlin (PlatformIO with VSCode) guide.

Changes to Slicer Start G-code

The W in Prusa's G28 W ; home all without mesh bed level default G-code does not exist in Marlin and G80 ; mesh bed leveling cancels the current motion mode, so no bed leveling will take place. See the Changes to Start G-code wiki article for example start G-code scripts from popular slicers for required changes.

Upgrade Caveats

As noted in the Supported Hardware Upgrades section above, the stock Einsy board & Power Panic are not supported. This firmware is based on Marlin bugfix-2.1.x with options specifically tailored to a Prusa MK3S/+ Bear with various hardware upgrades. You will lose Prusa firmware features like the setup wizards, automatic calibration, etc., but you can now use a variety of 32-bit boards, modern TMC drivers, and a bunch of other hardware by enabling a few config options in Prusa_AIO_Configuration.h.
