For some reason some of my filament seems to roll over in the MMU2 spool holders to form an overlapped loop on unloading. When the MMU2 pulls the filament back in for the next load the loop rolls over on itself and can snap or form a little knot. I found that having small vertical obstruction next to the loop will bump it over into an opened up loop instead of the knotted off loop.
I designed the originally to use a 0.5" PVC pipe (should be ~200mm long) and later converted the design to use some 3mm diameter (~300mm long) bamboo skewers I had laying around. Both designs seem to work equally well.
