💡 Workaround for running the newest PrusaSlicer version 2.8.0 (Flatpak) on a Raspberry Pi CM4 (uConsole)

[cryinkfly]

What works:

• The program can be used as a Flatpak version on the Raspberry Pi CM4, 4, ... with a few restrictions.
• Most of the functions work, such as importing and exporting files or editing the models.

What does not:

• Logging in with your own user account during and after the initial configuration does not currently work!
• Export/Slicing a G-code file, it hangs* at 90%!

*But it doesn't seem to be a direct Raspberry Pi issue, as this issue has also occurred on Windows and macOS in the past.

Testing:

• Workaround: Prusaslicer -> right click -> simplify -> extra high -> apply. The result slices quickly???

Installation/Workarounds:

First you need to install and configure Flatpak on your system using the following command in Terminal:

sudo apt install flatpak
flatpak remote-add --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo

Then you have to restart the Raspberry Pi with this command, for example:

sudo reboot

Next, install PrusaSlicer with the following command:

flatpak install flathub com.prusa3d.PrusaSlicer

And after installation, the program must be run with the following command*:

MESA_GL_VERSION_OVERRIDE=3.3 flatpak run com.prusa3d.PrusaSlicer

... so that this error does not pop up: PrusaSlicer requires OpenGL 3.2 capable graphics driver to run correctly

_*But you can edit the desktop file so that you can open the program via the start menu! On the standard desktop (LXDE) click on the start menu icon (raspberry logo) -> Graphics -> right-click on PrusaSlicer -> .desktop content -> in the command field, enter the following at the very beginning with a space after it: "MESA_GL_VERSIONOVERRIDE=3.3" -> Then click OK and you're done!

And if you want to use the Prusa GCode viewer, just adjust the desktop file in the same way.

What was not tested:

• I haven't yet checked whether you can flash or update the firmware of a connected 3D printer.
