my models keep getting knocked off. what to do?
(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)
That first layer looks really rough, although it's hard to tell for sure from the photo.
In my experience the most common reason for prints getting knocked off is a poor first layer, so the print lifts off slightly and then the nozzle hits it.
