problem with filament
Hello,
I've a lot of problem with my MMU2 and filaments (I used only PLA 1.75mm).
At start it work well, load/unload/print are perfect...... but after a while (random time, few day, few week, 10m or 100m of filament used, ...), the all system break down and I get lot of problem : MMU2 cannot push the filament in the extruder, filament jamed in the extruder, impossible unload, ....
I've test a few different type of filament (prusament, amazon filament, TIANSE), and all have the problem.
The room where i stock my filament is quite normal, normal temperature and no moisture.
I print in single color (multicolor never worked well .....), and at the end, I have maybe 1 success for 100 failure .... quite annoying.
Did someone have also that kind of problem ? And maybe a solution ?
Thanks in advance 🙂

Check the failing filament for a grind spot. Maybe you have to much spring tension.
