After slicing, circles appear to cut into edges... What's going on?

 

Here is the used stl file: https://www.printables.com/model/411360-clearance-gauge/files

The wall is probably too thin to print with your settings. However without a copy of your project file it’s impossible to be certain. Save your project from PRUSA slicer using File>save project as then zip up the 3mf saved and attach it.  If it’s not zipped up the forum will just silently not attach it, no warning.

Thank you for the warning and advice; here's the file:

peg set 7mm

Had a look and measured the wall thickness.  Most of them are placed 0.3mm away from the outer wall, although a couple are placed 0.286 away.  Given that your first layer perimeter extrusion is set to 0.5 and your external extrusion is set to 0.45 then naturally they wont be sliced.  Even switching from Classic to Arachne which varies extrusion width doesn't pick them all up as its just too thin for your nozzle size.  

Given that these look like calibration parts from their shape and name you don't really want arachne anyway.  Trying to calibrate extrusion when the slicer is varying the thing you are trying to measure is a bit pointless.

You can make the slicer pick the walls up by changing both your perimeter and first layer extrusion to 0.28 but your nozzle isn't really designed to print that thin.  Which is why the default extrusion width for a 0.4 is normally configured as 0.45mm.

Also one other thing, not related to the perimeters, but you have solid infill threshold set to 70.  That means the slicer is filling these parts with solid infill rather than using a normal infill pattern.  That usually leads to some over extrusion, which again if these are calibration pegs designed to fit in a hole is not something you want.

Okay I will try this sometime later to see how it goes, thank you!
