Hello everyone, I'm starting to get really frustrated with my Kobra S1. Image 1 and image 2 were printed with the same profile and filament settings. Why are the differences in quality and layer lines so significant? I've performed all the calibrations using the Orca slicer and followed all the tips with rinkhals, etc. After the calibrations and setting the values, the prints are perfect for the first two runs, and then this happens. I'm printing with Anycubic PLA.
