Cutting edges look like toothed

Hi. It depends a bit on the material I cut, but almost always the cutting edges are a bit toothed – every 8 mm or so a tooth. It’s like little waves on the edges, I see them and can feel them when gliding with the fingers over the edges. I tried different speeds, but it doesn’t make a difference. Any idea where they come from and how to prevent? The SVG is made with Inkscape 1.2. Thank for hints, Christian
