Brand new um 2 - Jammed within 2 minutes cannot clear

Recommended Posts

Hi,

After buying a number of um 1's, cubex's etc we have been given a um2... afetr unboxing, following the procedure, etc I'm guessing it was too close to the plate or something, it's jammed again (just like the good old um1) and I'm not able to clear the nozzle.

Can anyone offer any advice?

I don't want to spend 90% of my time fixing ultimakers!

Thanks

Jem :-P

Hi Jemma,

Are you sure that the filament is reaching the nozzle?

Have you tried feeding some filaments by the top of the nozzle (by removing the bowden tube)

The atomic method linked below show how to unclog a nozzle (you can follow the steps to feed by hand).

Ps: you can raise the temp to 230°c 240°c no need to go up to 260°c at first (worth the try if it remains clogged)

The filament occasionally catches on the entrance to the white (teflon) part of the hot end, given that the printer is new (AIUI), then that was probably the problem rather than dirt. You can avoid it in future by giving the filament a point rather a flat end.

I would avoid resorting to excessively high temperatures, as that can cause longer term issues.

Hi Unfortunately its jammed again... I've trying doing the above method but the filament won't even come out of the bowden tube. It's completely jammed... any ideas how to remove it without damaging the machine??

I also assume that there is a jam in the extruder itself which caused the problem in the first place. the only thing I can think that caused it, is printing low quality fast speed....

Excellent point(!)  We received our new UM2E+ today, and material would not come out.  Tried many things.  What fixed it was - cut a point on the end but also straighten it.

Off the spool the filament end has a curve.  We bent the last 2-3" (50-75mm) straight, cut a point on it, and that did the trick.
