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.
Strap in for the first Cura release of 2024! This 5.7 beta release brings new material profiles as well as cloud printing for Method series printers, and introduces a powerful new way of sharing print settings using printer-agnostic project files! Also, if you want to download the cute dinosaur card holder featured below, it was specially designed for this release and can be found on Thingiverse!
S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
(Sorry, was out of office when this released)
This update is for...
All UltiMaker S series
New features
Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

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!
