Clone this repository and checkout the correct branch for your desired release version.

Set your printer model.
- For MK3 --> skip to step 3.
- If you have a different printer model, follow step 2.b from Windows build
-
Run
sudo ./build.sh
- Output hex file is at
"PrusaFirmware/lang/firmware.hex"
. In the same folder you can hex files for other languages as well.
- Output hex file is at
-
Connect your printer and flash with PrusaSlicer ( Configuration --> Flash printer firmware ) or Slic3r PE.
- If you wish to flash from Arduino, follow step 2.c from Windows build first.
Notes:
The script downloads Arduino with our modifications and Rambo board support installed, unpacks it into folder PF-build-env-\<version\>
on the same level, as your Prusa-Firmware folder is located, builds firmware for MK3 using that Arduino in Prusa-Firmware-build folder on the same level as Prusa-Firmware, runs secondary language support scripts. Firmware with secondary language support is generated in lang subfolder. Use firmware.hex for MK3 variant. Use firmware_\<lang\>.hex
for other printers. Don't forget to follow step 2.b first for non-MK3 printers.
Note: Multi language build is not supported.
a. Install "Arduino Software IDE"
from the official website https://www.arduino.cc -> Software->Downloads
It is recommended to use version "1.8.5"
, as it is used on out build server to produce official builds.
b. Setup Arduino to use Prusa Rambo board definition
- Open Arduino and navigate to File -> Preferences -> Settings
- To the text field
"Additional Boards Manager URLSs"
addhttps://raw.githubusercontent.com/prusa3d/Arduino_Boards/master/IDE_Board_Manager/package_prusa3d_index.json
- Open Board manager (
Tools->Board->Board manager
), and installPrusa Research AVR MK3 RAMBo EINSy board
c. Modify compiler flags in platform.txt
file
-
The platform.txt file can be found in Arduino instalation directory, or after Arduino has been updated at:
"C:\Users\(user)\AppData\Local\Arduino15\packages\arduino\hardware\avr\(version)"
If you can locate the file in both places, file from user profile is probably used. -
Add
"-Wl,-u,vfprintf -lprintf_flt -lm"
to"compiler.c.elf.flags="
before existing flag "-Wl,--gc-sections"For example:
"compiler.c.elf.flags=-w -Os -Wl,-u,vfprintf -lprintf_flt -lm -Wl,--gc-sections"
Notes:
In the case of persistent compilation problems, check the version of the currently used C/C++ compiler (GCC) - should be at leas 4.8.1
;
If you are not sure where the file is placed (depends on how "Arduino Software IDE"
was installed), you can use the search feature within the file system
Name collision for "LiquidCrystal"
library known from previous versions is now obsolete (so there is no need to delete or rename original file/-s)
a. Clone this repositoryhttps://github.com/prusa3d/Prusa-Firmware/
to your local drive.
b. In the subdirectory "Firmware/variants/"
select the configuration file (.h
) corresponding to your printer model, make copy named "Configuration_prusa.h"
(or make simple renaming) and copy it into "Firmware/"
directory.
c. In file "Firmware/config.h"
set LANG_MODE to 0.
d. Run "Arduino IDE"
; select the file "Firmware.ino"
from the subdirectory "Firmware/"
at the location, where you placed the source code File->Open
Make the desired code customizations; all changes are on your own risk!
e. Select the target board "Tools->Board->PrusaResearch Einsy RAMBo"
f. Run the compilation Sketch->Verify/Compile
g. Upload the result code into the connected printer Sketch->Upload
- or you can also save the output code to the file (in so called
HEX
-format)"Firmware.ino.rambo.hex"
:Sketch->ExportCompiledBinary
and then upload it to the printer using the program"FirmwareUpdater"
note: this file is created in the directory"Firmware/"

After the installation and reboot please open your Ubuntu bash and do following steps
-
run command
apt-get update

to install zip run
apt-get install zip

- Linux is case sensetive so please don't forget to use capital letters where needed, like changing to a directory
- To change the path to your Prusa-Firmware location you downloaded and unzipped
- Example: You files are under
C:\Users\<your-username>\Downloads\Prusa-Firmware-MK3
- use under Ubuntu the following command
cd /mnt/c/Users/<your-username>/Downloads/Prusa-Firmware-MK3
to change to the right folder
- Example: You files are under
- Unix and windows have different line endings (LF vs CRLF), try dos2unix to convert
- This should fix the
"$'\r': command not found"
error - to install run
apt-get install dos2unix
- This should fix the
- open Ubuntu bash
- change to your source code folder (case sensitive)
- run
./PF-build.sh
- follow the instructions

- follow the instructions
- c++11 compiler e.g. g++ 6.3.1
- cmake
- build system - ninja or gnu make
Create a folder where you want to build tests.
Example:
cd ..
mkdir Prusa-Firmware-test
Generate build scripts in target folder.
Example:
cd Prusa-Firmware-test
cmake -G "Eclipse CDT4 - Ninja" ../Prusa-Firmware
or for DEBUG build:
cmake -G "Eclipse CDT4 - Ninja" -DCMAKE_BUILD_TYPE=Debug ../Prusa-Firmware
Build it.
Example:
ninja
./tests
run doxygen in Firmware folder
Q:I built firmware using Arduino and I see "?" instead of numbers in printer user interface.
A:Step 1.c was ommited or you updated Arduino and now platform.txt located somewhere in your user profile is used.
Q:I built firmware using Arduino and printer now speaks Klingon (nonsense characters and symbols are displayed @^#$&*°;~ÿ)
A:Step 2.c was omitted.
Q:What environment does Prusa use to build the firmware in the first place?
A:Our production builds are 99.9% equivalent to https://github.com/prusa3d/Prusa-Firmware#linux this is also easiest way to build as only one step is needed - run single script, which downloads patched Arduino from github, builds using it, then extracts translated strings and creates language variants (for MK2x) or language hex file for external SPI flash (MK3x). But you need Linux or Linux in virtual machine. This is also what happens when you open pull request to our repository - all variants are built by Travis https://travis-ci.org/ (to check for compilation errors). You can see, what is happening in .travis.yml. It would be also possible to get hex built by travis, only deploy step is missing in .travis.yml. You can get inspiration how to deploy hex by travis and how to setup travis in https://github.com/prusa3d/MM-control-01/ repository. Final hex is located in ./lang/firmware.hex Community reproduced this for Windows in https://github.com/prusa3d/Prusa-Firmware#using-linux-subsystem-under-windows-10-64-bit or https://github.com/prusa3d/Prusa-Firmware#using-git-bash-under-windows-10-64-bit .
Q:Why are build instructions for Arduino mess.
Y:We are too lazy to ship proper board definition for Arduino. We plan to swich to cmake + ninja to be inherently multiplatform, easily integrate build tools, suport more IDEs, get 10 times shorter build times and be able to update compiler whenewer we want.
