Solid infill rumbles over infill; bridge infill in other places is better
Hi,
My current print subject is causing me a little headaches at one point. There are infilled areas and when it comes to closing them on the top, in one place, the nozzle rumbles really quickly over the infill parts, causing bad noise and shaking the entire Z axis of my Mini printer. That goes for a few layers until a diagonal top layer is done. This is the first screenshot, the long purple lines in the lower part.
A few layers further, at the other part (top in the image), bridge infill is used. This prints very slowly (and with the print fan at 100%) and flows nicely. No noise, no shaking.
What's going wrong here? Why can't I also have the bridge infill in the first instance?
Printer is Prusa Mini with Input Shaper profile, material Prusament PLA, layer height 0.1 mm. PrusaSlicer 2.9.2.
RE:
Try rectilinear, its safer, less noisy and fast, while gyroid is better when you need to fill it with a resin.

I had the default value first ("Gitternetz" in German). It was just as bad. So I tried that wavy gyroid thing. Meanwhile I made the lower part 1 mm wider and now I get proper bridge infill according to the print preview. I'll see how it goes in 12 minutes.
With "rectilinear", did you mean the infill pattern or the pattern of some top or whatever layer?

Infill.
For 100% infill or top/bottom PrusaSlicer turns into rectilinear by default, if I remember correctly.

Thanks, understood. I did some more reading on the patterns and how grid has that overlapping effect where the lines are crossing, which rectilinear does not. Should be good, I'll try that now.
