Can the depth of the "tracks" on the filament be used as a guide for the right tension?
What about when changing filaments and then going back to the original filament? Do I need to discard the section that was already in the bowden tube and that has "track" marks on it? Can the feeder have a good grip on already used section?
I am getting occasional clicking from the motor skipping and some underextrusion. I also had to clean the bowden tube from the small pieces and strings of PLA.
If the pressure is to low you will get slipping marks as in your picture because the grip will not be strong enough. If the pressure is to high the filament can be deformed or you will get the motor skipping back all the time.
But i have to remark it has been long since i used the original Feeder... i now use mine with a MK8.
