my models keep getting knocked off. what to do?
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)

You can try adding a brim (or a raft if that doesn't help) and see how that goes - tall and skinny models can require some extra bed adhesion to be stable, and that can affect the very top if the model is moving enough for the extruder to hit it. Worth a try...
This already had a brim but it is quite ugly. The thing is I had the same failure while printing a bigger object like a Stormtrooper helmet. Randomly popped off the bed after like 2.5 hours
