I just stopped a failing print and noticed some weird extrusions happening (not english native speaker, also I'm a 3d printing noob, don't know whether that's the right word). You can see it in the image. Any tips to improve printing quality?
I'm printing on an Ender 3 V3 SE. This print was with standard settings.
EDIT: as a clarification, this isn't why I stopped the print. It failed to adhere to the print plate at some spots. Redid my z offset and hopefully that solved it.
Turns out there was some stuff under the print bed! Thanks for that info. Had to recalibrate after removing them, and that got me the first successful print again. Unfortunately couldn't really look between the print head and bed, as it's a really weird angle and there's very little to see. Will try again when I have another spot for the printer to put.
