First mm always faulty? (feddit.de)

I cant get my Anycubic Kobra 2 with Klipper to print correct. The first mm of each layer are faulty, resulting in a bad tooth in gears.

I tried to slow down the print, tried to minimize/deactivate retraction, fiddled with z offset and first layer height, lowered bed temp, altered the extrusion rate. Nothing works. Everything else seems fine, slim z seam, nice walls, no over/underextrusion.

Anyone got a hint how i could fix that?

Edit: I cancelled that Print, the Problem is only in the first tooth:

the tooth in the marking should look like the ones above it.

My guess is that is a slicer error because it couldn’t make the shape with a combination of the tooth size on the gear and wall thickness settings. Does it look right in the slicer after it is sliced on the first layer?

It looks correct in the slicer. I changed the slicer btw and with cura everything works fine. So its something in PrusaSlicer. Will test some more today.
