This repository includes source code and firmware releases for the Original Prusa 3D printers based on the 32-bit ARM microcontrollers.
The currently supported model is:
- Original Prusa MINI
- Python 3.6 or newer
Run git clone --recurse https://github.com/prusa3d/Prusa-Firmware-Buddy.git
.
In the case you already cloned the repository without the --recurse
flag, run git submodule update --init
.
Run python utils/build.py
. The binaries are then going to be stored under ./build/products
.
- Without any arguments, it will build a release version of the firmware for all supported printers and bootloader settings.
- To generate
.bbf
versions of the firmware, use:./utils/build.py --generate-bbf
. - Use
--build-type
to select build configurations to be built (debug
,release
). - Use
--printer
to select for which printers the firmware should be built. - By default, it will build the firmware in "prerelease mode" set to
beta
. You can change the prerelease using--prerelease alpha
, or use--final
to build a final version of the firmware. - Use
--host-tools
to include host tools in the build (bin2cc
,png2font
, ...) - Find more options using the
--help
flag!
Build the firmware for MINI in debug
mode:
python utils/build.py --printer mini --build-type debug
Build final version for all printers and create signed .bbf
versions:
python utils/build.py --final --generate-bbf --signing-key <path-to-private-key>
Build the firmware for MINI using a custom version of gcc-arm-none-eabi (available in $PATH
) and use Make
instead of Ninja
(not recommended):
python utils/build.py --printer mini --toolchain cmake/AnyGccArmNoneEabi.cmake --generator 'Unix Makefiles'
The build process of this project is driven by CMake and build.py
is just a high-level wrapper around it. As most modern IDEs support some kind of CMake integration, it should be possible to use almost any editor for development. Below are some documents describing how to setup some popular text editors.
To install custom firmware, you have to break the appendix on the board. Learn how to in the following article https://help.prusa3d.com/article/zoiw36imrs-flashing-custom-firmware.
