Hotend is getting plugged often (N2)

Postby Ireeb » Sat Apr 21, 2018 8:42 pm

Hi community,

I have the problem that it seems like my hotend is getting plugged by filament often. It happens especially with non-Raise-filament, but also with the original filament. Do you have any tips on how to avoid this or what could cause this in the first place?

Printer: N2
Slicer: Simplify 3D

Thanks in advance!

What kind of filament are you using? PLA, ABS, PETG, etc?
Also what nozzle temp are you printing at?

Check to see if your fans are on, as heat creep up the hotend can cause a jam.

Yea, I've had that happen with PLA before

The two times it happened to me though was when the print finished and the extruder cooled down. It was a couple of hours before I got back to it

At the moment only PLA, usually at 210°C. The fans are all active.
I also thought heat creep is a possible explanation, but what other ways are there to minimize them? Guessing from your question, could lowering the print temperature help? (But wouldn't that increase the likeliness of plugging the nozzle as well since that would mean the filament has a higher viscosity?)
