## Configuring Prusa All-in-One Firmware
To configure this firmware, enable options in [`Prusa_AIO_Configuration.h`](Marlin/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](//code.visualstudio.com/) with [PlatformIO](//docs.platformio.org/en/latest/integration/ide/vscode.html#platformio-ide-for-vscode). Detailed setup instructions can be found in the [Installing Marlin (PlatformIO with VSCode)](//marlinfw.org/docs/basics/install_platformio_vscode.html) guide.
## Supported Hardware Upgrades

- **Probes**: BLTouch and SuperPINDA
- NeoPixels
- ESP WiFi addon running [ESP3D](//github.com/luc-github/ESP3D)
## 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](//github.com/thisiskeithb/PrusaAIO/wiki/Slicer-G%E2%80%90Code-Notes) wiki article for example start G-code scripts from popular slicers for required changes.
## Upgrade Caveats
As noted in the [Supported Hardware Upgrades](#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/+ or MK2.5S 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`](Marlin/Prusa_AIO_Configuration.h).
