PLA accumulating over and on the nozzle, flowing from above
Posted
· PLA accumulating over and on the nozzle, flowing from above
Looks like a leaking nozzle, maybe not tightened enough? Or maybe there was some debris on the thread when it was tightened? I think they need to be tightened when warm, so any filament-remains on the thread would be molten. If fastened cold, it could leak. But I am not familiar with an UMO, so it is best if you google for a manual how to disassemble the UMO-nozzle.

Agreed...It sounds like the nozzle needs to be tightened when heated, and was probably accidentally tightened when cold.
You can do an atomic/cold pull before changing the nozzle to make sure debris is not preventing the nozzle from tightening all the way.

Ok thanks I have cleaned the overflowing PLA and re-tighten the nozzle while hot, now there seems to be no leak anymore.
See you around!
