Struggling to get slicer to generate concentric fill
I have a part that is essentially a ring with some numbers on the top (prints fine), and a series of half-cylendar cutouts on the bottom. Those cutouts sometimes print good and sometimes not, and I looked at the layers in the slicer and noticed that the infill is always straight lines and depending on the angle of the infil vs the cutout it would bridge great or terribly. I tried changing infills and everything to concentric to force it to always print allong the path of the ring to always bridge the gaps but it didn't change the resulting tool path in PrusaSlicer.
SW version: 2.2.0 WIn64

Using 2.2 you should probably try using a modifier with perimeters for best results, sad to say, I can't recommend a more recent version of slicer for better performance with concentric fill. You can of course use fractions to help, but you will get your best outcome using a modifier to use perimeters, giving the best outcome for the top layers as always. The newer version of Slicer with the Arachne perimeter generator could help, but they screwed up so much else that its not worth it.
So try using perimeters with your project they should conform nicely to the shapes you mention. If they don't then post a zipped up Project file exported from Prusaslicer and we can give you better advice based on your project.I still have 2.2 installed for just such an occasion.
