Material leaking above nozzle advice?

Recommended Posts

Posted · Material leaking above nozzle advice?

I have an ultimaker 2 + extended.

I'd just completed a 8 hour long print, and started a second one an hour later. I noticed a lot of material around the nozzle connection point. I figured that it might not have been tight, so I removed the material with the change option, heated up the nozzle, and then removed it. There was melted material around the threads, and I scraped a lot out around where the nozzle screws to the head. the filament was natural, and it was blacked from burning. I removed as much as possible, and did an atomic on it to see if maybe the tip was clogged... it seemed fine after a few pulls, so I reassembled and have started printing again. The nozzle did not seem loose when I removed it. \

I can't really find a reference to this issue, what causes it, and what the cure is. Any links, or advice anyone can offer on this issue?

I guess I'll know in the am if the problem still exists I guess.
