Ultimaker 3e printcores fatally glued together

Posted · Ultimaker 3e printcores fatally glued together

Hello dear forum,

 

last week I started a print with renkforce glow-in-the-dark pla-filament.

Unfortunately I left the printer alone just after I sent the printfile to it.

 

When I came back after two hours, the filament got completely stuck into both cores of the print head. The lower part of the filament clog was scratching the glass bed which got delocated from the holders by its movement.

 

After dragging out most of the glued filament (which took a couple of hours) I reached now a point where both printcores are still stucked although most of the glued filament is out now.


My questions:

Did anyone have the same problem yet?

Do You know a way of getting the stucked printcores out of the print head without using an angle grinder?

 

Thank You a lot in advance!

 

Daniel

I've seen similar on a UM3, heat gun and alot of time, it's possible to fix. Just keep working at it. It's also PLA, so should be fairly easy.

Hey Theo,

you‘ve been right. The heat gun solved it. Now the printcores look a bit used. But everything works fine again.

Thank You.
