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)
The only time I’ve ever had the extruder knocking down prints is when the bed was out of level.
I've had it happen when I partially lose adhesion and the print starts to warp.
