(lm.boing.icu)
Hi, I'm new to printing. I got myself a Kobra 2 and it was printing fine when I got it. But recently it started to knock the prints off at random times. I have done several recalibrations, adjusted the Z offset up and down. What I have noticed is that all of these models seem to have a small overflow of material which I'm guessing the nozzle is bumping into. But I have no idea what causes it. I'll post the latest print that failed, there the extra material is more pronounced than usual. Any suggestions what I should adjust? (Btw I'm using Octoprint)
I have cleaned the bed already with alcohol and microfiber cloth. Yeah the brim is supposed to be cylindrical but it obviously isn't :D . Is that a modification I should do in Prusa Slicer? For the first layer height
You may want to calibrate your z height. The first layer should have a slight squish to it in profile, like a cat tongue biscuit.
