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.

    Looks like that’s a bed leveling problem. You can change the z height all you want but if the bed isn’t level to your Z axis, one side will always be too shallow and one side tooDutch? If it gets too close the nozzle it’ll put out almost no plastic which I think is what youre seeing.

        Oh I couldn’t even see that tooth at first. I just saw the varying layer width.

        That’s definitely going to be a slicer or model error. Make sure your input STL doesn’t have any missing faces or geometry and that the teeth were generated correctly
