I can't compile MK4 firmware  

RE: I can't compile MK4 firmware

did you manage to solve it? I have the same problem

Posted by: @juan-pucholdid you manage to solve it? I have the same problem

Hello, I need help. When I try to compile MK4 firmware I get (firmware 5.0.0-alpha4 compiles ok, but since this version is not working):

 

PS C:\Caribou320_Firmware\MK4\Prusa-Firmware-Buddy-5.0.1> python utils/build.py --preset mk4 --generate-bbf

Switching to Buddy's virtual environment.

You can disable this by defining BUDDY_NO_VIRTUALENV env. variable.

Hello, i have the same issue...

Same here. Did anyone solve the issue?

opened a bug report on github: https://github.com/prusa3d/Prusa-Firmware-Buddy/issues/3579

Github - bkerler commented Dec 12, 2023

It's easy to fix. install virtualenv, then do a python -m venv .venv in the git directory and it will work just fine using the build script.

RE: I can't compile MK4 firmware

I managed to solve it by installing version 3.11 of Python, with 3.12 it doesn't work for me.

RE:

Hello,

from firmware 5.0.0-alpha4 (that compiles fine) I copy the folders .venv and .dependencies to the new firmware folder and then it compiles well

Happy printing!!

RE: I can't compile MK4 firmware

😉 👍 

I tried the compilation process on an ARM64 system - no chance.

On an x86/x64 system compile should work after .venv and. dependencies have been added.

Closed the bugreport on github, because problem solved!

RE:

Now it also works for me (Mac M1).

So, now since I am able to change some settings in the firmware (I want to disable Z_SAFE_HOMING), I can finally compile my own firmware.

Unfortunately the commands for the compelling are not well documented.

This is the basic command:

python3 utils/build.py --preset mk4 --generate-bbf

Prusa is using this (as mentioned on GitHub):

python3 utils/build.py --preset mk4 --build-type release --bootloader yes --generate-bbf --generate-dfu --no-store-output --version-suffix=-BETA+5729.PR3570.B5 --version-suffix-short=-BETA+5729 -DCUSTOM_COMPILE_OPTIONS:STRING=-Werror -DDEVELOPMENT_ITEMS_ENABLED:BOOL=yes

I wonder which of these settings are eventually necessary to compile a correct firmware

RE: I can't compile MK4 firmware

I have added an alias in ~/.bashrc:

alias python='/usr/bin/python3'

This allows you to start the compilation process as follows:

python utils/build.py --preset mk4 --generate-bbf

RE: I can't compile MK4 firmware

I have my firmware folder in C:\Users\Y\Desktop\3D Printers\Edited_Mini_Firmware\Prusa-Firmware-Buddy-5.1.2

(Simply the unzipped source code with a few edits in config)

After installing virtualenv and running a "python -m venv .venv" in the same directory, I keep getting this error upon the command "python utils/build.py --preset mini --generate-bbf":

C:\Users\Y\Desktop\3D Printers\Edited_Mini_Firmware\Prusa-Firmware-Buddy-5.1.2>python utils/build.py --preset mini --generate-bbf

Switching to Buddy's virtual environment.

You can disable this by setting the BUDDY_NO_VIRTUALENV=1 env. variable.

Doing something wrong?

RE: I can't compile MK4 firmware

Bumping. I'm not owed an answer, but I still would like to say that from being able to flash without any troube to, getting all this errors (and the documentation page hasn't been updated since) seems like a downgrade. Editing the Marlin config shouldn't be reserved to software developer - level skill.
