Thanks for your offer. I tried cura slicer and there the problem is gone. So it is a problem in PrusaSlicer. Here is the gcode, please dont put too much effort into 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.
It looks correct in the slicer. I changed the slicer btw and with cura everything works fine. So its something in PrusaSlicer. Will test some more today.
In the first photo the outter perimeters were completely print and the inner started to print. The outer perimeter from the first tooth is missing, so theres only the inner one. In PrusaSlicer the perimeters are correct, the nozzle moves correctly but no filament is coming out. It begins with the second tooth. I let the nozzle draw 5 lines prior to the printing so the pressure in the hot end is correct. I guess its a retraction issue, maybe the slicer retraction settings are ignored by the firmware, ill look into that tomorrow.
Try PROBE_CALIBRATE in the Console. Use a piece of paper, it should fit between nozzle and bed, you should be able to move it with slight resistance. Save it with SAVE_CONFIG.
Should be a slicer problem, with cura its gone...
