Hey Martin
Are you having this behavior on your filament when you are trying to print anything?
I haven't found an answer neither, the only way I can print is removing the damaged filament while the printer is paused, and then continue printing (I'm using Cura 12.08) but is a pain in the ass to be checking the printer for hours.
I've tried to print the same feeder than you but i haven't had luck with it. I keep looking an answer as you. I hope some day we found it.
P.S. Sry for my english
