Tiny solid infill
Hello,
is there a way to remove this tiny solid infill wiggling? I tried to set the Solid infill threshold higher but that does nothing.
I want to do so because a print once wiggled itself of the printbed because of this. My workaround is to reduce the speed of solid infill which is not ideal because of the increase in printtime.
Thanks
Kind regards

If you're referring to the little wiggles up against the walls, those are most likely from Print Settings->Layers and perimeters->Quality->Ensure vertical shell thickness. PrusaSlicer adds material to ensure thin sloping walls don't have gaps. When you turn that off, quality may degrade. Here's a 50mm sphere sliced with an without that option enabled at 0% infill:
You can try different infill patterns, but gyroid produces smooth angles that shouldn't cause problems. You could try using modifiers to adjust infill in parts of a model.
If you care to save off a 3MF project file with your part and settings, we can take more of a look. Nothing in that print looks particularly challenging.

If your prints are coming loose, you have bed adhesion issues. Even if you don't think this is the cause, it's always a good idea to make sure your PEI surface is clean before trying any other fixes. If it's a smooth PEI sheet, take it to the kitchen sink and give it a good dunk with Dawn (original formula, no vinegar or hand softener variants) dishwashing soap or your local equivalent (e.g. Fairy in UK). Use a clean paper towel to clean it off, and another to dry it. Avoid using any sponge or cloth that has been in contact with grease. Above all else, avoid touching the PEI print surface. Once it's good and clean, you should be able to use 91%+ isopropyl alcohol between prints, 100% acetone when that fails , and another dunk when acetone fails. Worst-case, use a 3M 7445 ScotchBrite pad or equivalent on smooth PEI to give it a very light buff, but only infrequently. If you've got a textured powder-coated PEI print surface, the official instructions are to use 91%+ isopropyl alcohol on it only. Rumors persist that some tribes deep in the jungle have had good luck getting started with these sheets by giving them a wipe with 100% acetone and a dunk with Dawn. Either way, there's no real warranty on these sheets. YMMV.

Hi, thanks for the reply but it did not refer to my question.

No but it will fix your problem.

Hi, thanks for the nother reply. Sorry to say this but my problem is not adhesion. The problem is the wiggle in the PrusaSlicer. I wanted to know how to get rid of the wiggle in the slicer. That was my question and nothing else.

RE: Tiny solid infill
Agree it shouldn't come off the bed and dawn/fairy are the answer to that.
I don't know the settings to remove particular sections of infill but you could try increasing perimeters or change the fill pattern to say cubic which doesn't wiggle the bed so much.
RE: Tiny solid infill
Actually concentric with reduced infill might be a better option.

Hi,
the vertical shell thickness setting did it. Thanks! I was not aware of that setting.
