not all walls filled out - hollow walls

[Illusionist1969]

PrusaSlicer vers.: 2.4.0, also the new Beta, and older versions i have tried.

OS: Windows 10, Windows11 - also tried with older Windows version

My Printer is the original Prusa MK3s - without modifications and the actual firmware

Behavior/issue:
My model is constructed with Fusion 360 with massive walls (all walls are between 3mm and 5mm
one of these walls is constructed with 80degrees with a hight of 65mm.
After slicing, the wall is not filled, it is hollowed instead of having infill ! (??) - in Cura it is massive with infill as expected, but not in prusaSlicer, not matter if i use "thin walls" or other settings or if i change infill to a higher volume.

Hope you can help me - i dont want to use Cura :-( or two applications

unfortunately i cannot attach the stl file (not supported) - i have tried now the latest beta version of PrusaSlicer, same issue
some minutes ago, i installed an oder version of PrusaSlicer (2.3 beta) to see if the same behaviour exists, and the answer is yes.
Walls with an angle of 80degrees and 4mm thicknes are not filled with infill :(
I hope you were telling me that i have a false configuration, or i have not ticked any box ....

Kind regards,
Manfred

FYI -files must be zipped up to attach. Also saved project files (3mf saved from PS) are much preferred over stl files and it allows the devs to look at all your settings.

Thank you so much neophyl - now the stl with 3mf is enclosed as zip-file 🔢
i really believe my handling was wrong because i cannot imagine that i am the first one who detects this problem.

in the meanwhile, i found a workaround: Using 4 perimeters could work (i will try), but it is not a solution

Everything is ok. You probably want to uncheck Print Settings -> Infill -> Only infill where needed.

Does it solve the issue?

[Illusionist1969]

YES - i knew this must be an issue between desk and chair :)

Thank you sooo much !!!
