Both PLA and PVA got 'broken' at the end of the feeder and stopped extruding the material?

Posted · Both PLA and PVA got 'broken' at the end of the feeder and stopped extruding the material?

Hello everyone.

I have a Ultimaker 3 extended, and something really weird happened. I started a print, which worked normal for 3 hours, then I left home and came back in 6 hours, and it seemed like the material stopped extruding hours ago and didn't print much further after the three hours. The PVA extruder looks burnt, and the PLA had material all over it like- completely covered. I wanted to check if the material got stuck because of bad temperature, however I knew that I've set it up right, and then when I unloaded the materials I saw that they we're BOTH bent in and a little broken, right where their end was getting into the feeder (I'll attach a picture.) I really can't figure out how and why this happened, especially how it happened to both of the materials...

Does anyone possibly know the cause?

    P.S. and now the nozzle's seem to be clogged. How is that possible, besides the temperature being wrong, which it isnt?

    I have added a picture but I don't know why it's not showing :s

    No worries. To show the picture, make sure you have put in the Http:/ or HTTPS:/. It does not like the generic www.yourlocation.com.

    But, having seen the pic, I can say, with a lot of certainty (and that ALWAYS gets me into trouble) is that your tension on the feeder is not correct.I had that happen a lot.

    Check here, the first pic has the same issue:

    Be aware that different manufacturers of filament require different tensions sometimes as well as different types. And make sure your roll has not binded against itself (crossed lines, etc) and has a free, easy pull off the roll.

    Good luck!!
