Posted (edited) · Feeder grinding filament (Ultimaker Original)

Hey everyone,

 

eventhough this is not a new topic, I keep having trouble with filament grinding on my Ultimaker Original. I've had this printer since 2014 and this is the first real headache I've had with printing. The problem occured a while back when I noticed that longer prints weren't as good anymore as before (layers falling apart with prints having obvious marks of underextrusion) until at some point there was nothing coming out of the extrudor. I noticed there was no tension on the filament and when disassembling the feeder I noticed those typical "bite" marks caused due to constant grinding. I figured the nozzle might be jammed, so I made some cold pulls, but the problem remained. I figured maybe it was time to change the hot end after 6 years and after making the switch with a brand new one, the printer worked fine for a couple of minutes and the same problem occured again. I've attached the photo of the assembled printing head and so called "bite" mark on the filament.

 

I've tried reducing the tension on the feeder, cleaning the feeder, tried lowering printing speeds and rising the temperature but nothing seems to work. Once the printing process is initiated, the filament is grabbed and retracted, after that it doesn't feed and nothing comes out the extruder. At this point I'm a bit stuck, because everything worked fine up to this point. If there's a soul out there having the same headache I'd be more than grateful for some advice whatsoever 🙂

 

All the best,

Miha

    Another thing I forgot to write was, that if I remove the bovden tube and push a short piece of filament through the extrudor, everything works fine. If I made a cold pull, everything was clean inside, because I could see light through the nozzle hole, so assuming something gets clogged there isn't the case.

     

    I have a feeling that something gets stuck at the point where the bovden tube connects to the small white connector which goes to the teflon part. Then again, like I said, the printer worked for a couple of minutes and extrusion slowly stopped, so I am left without ideas what to look for.

     

    @gr5 I remember 6 years ago you had all the answers to my issues. If you have any ideas, what would be the case here?

    Did you tried reducing the "maximum retractation count" and increasing the "minimum extrusion distance window" settings in cura ? A too big retractation can grind the filament
