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.

    Right, ok, so I’m not particularly familiar with Cura… I use SuperSlicer which is a fork of Prusa (which is a fork of Slic3r). Neither slicer has a UI option for initial purge lines as far as I can tell.

    So for both Prusa and Cura you are using a block of custom start gcode to define the purge lines? Exactly the same gcode in both slicers?

    Could you please share the Cura gcode output in addition to the Prusa version you shared? I am curious what the difference is.
