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.
It’s a retraction issue. If the layer starts there and you are missing first few millimeters of filament, that means you’ve retracted filament too much. If it’s only on the first layer, adding skirt will help prime the nozzle. But if it’s present throughout the entire print and all the layers start there, which it seems to be the case, it’s retraction issue.
