Feeder keeps skipping
Model: Ultimater 2 Extended
Hey guys,
I'm a little bit confused. After hours of printing suddenly the feeder of my Ultimaker 2 Extended started skipping: Video: https://drive.google.com/file/d/0B7KyR2ULRkeQa3U3VW1INGg1bms/view?usp=sharing
What I already tried:
--> doesn't skip, when the hose is not inserted
changed nozzles
changed the hardness of the feeder
Have you got any ideas to help me? Because actually this skipping causes the feeder to not transport the filament fluently, so that the prints come out bad.
Thank you
Werner Koch
