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.

    Okay, thanks. I’m afraid I don’t have any further insight here, there’s obviously either a problem with the G-code or how the printer is executing that G-code, I suspect your idea about retraction might have something to it. Could you provide the G-code file? I don’t know if I will be able to get much out of it, but there are a number of G-code viewers and simulators that can help you understand better what’s going on.
