Mhm, that looks like both heat creep and warping. Maybe even curling.
- What material are you printing?
- And what kind of chamber temps do you see?
- Is your nozzle (still) straight?
To avoid warping, we need a really dry filament and clean build plate (water, dishwashing liquid, clean brush (dishwashing or nail brush) for a textured plate, microfibre cloth for Smooth PEI => thin smooth coat of glue by spreading around the PVA stick with a small paper towel).
Also, I was focusing on the colors and did not check the other settings. I always use honeycomb infill (non-crossing infill) to avoid speed bumps.
For PLA, I usually target 35-39°C chamber temp unless there’s ironing, many retracts or a prior heat creep like failure. In those cases, I try to stay below 35°C by just propping open the lid a bit more.
