Artifacts in the first layer
I keep getting these artifacts in the first layer, did automatic and manual flow calibration several times, cleaned my buildplate with degreaser, dishsoap, windex and IPA, still getting them every time. Reduced first layer infill speed from standard value to 50mm/s, still... With Archimedes spiral it mostly happens in the corners, with the standard diagonal pattern it's a bit worse (last pic)
Bambu PLA basic, dried for 12h.
Are there some screws loose, or could it the belt tension?
