Has anyone foudn other solutions for that jamming problem? I don't currently have enough space to set them far apart or as Jarcec has put them (see comments). Tried janking something between each buffer roller, but filament slips by those so I currently don't see any other way than enclosing each, which defeats the purpose for these.

@OeschMe I bought some 1 foot square pieces of thin acrylic on Amazon, then threw together some little feet and puth the sheets between the buffers, it keeps the filament from looping over into adjacent paths.
