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.
I changed every retraction setting ive found. 2x in PrusaSlicer, 1x on Klipper, nothing changes. But with Cura Slicer the problem is gone. So i obviously f*ed up some setting in PrusaSlicer. Will test more today.
Are you printing internal or external perimeters first?
In PrusaSlicer externals first, in cura outside to inside. Whats weird in cura, it prints the outter wall ls first half gears first, then the spokes from the second half.
That is interesting. Does CuraSlicer do the same priming lines? Have you tried the print with PrusaSlicer without the priming lines?
If you can figure out what Cura is doing differently in that section of the gcode you could put those lines in the custom gcode box in PrusaSlicer and get the same results.
It does the same priming lines, im using the same start gcode. Without it would miss the complete first half of the gears outter wall, oftem from the 5 lines only 3 get printed.
