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

In addition to the stock hardware (except the Einsy motherboard & Power Panic), the following upgrades are supported:
- Motherboards: BigTreeTech SKR 3.0 & 3.0 EZ, 2.0 with optional flash drive support, 1.4 & 1.4 Turbo, BTT002 1.0, SKR Mini E3 V3.x & V2, MKS/Makerbase Robin Nano V3 & 3.1 with optional flash drive support, SGEN_L V2, and Robin E3 & E3D V1.x
- Drivers: TMC2209s, TMC5160s, and TMC2130s

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.
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.
