Think this will be a mod I do on the future. All extruder produce that dust mine does the same thing. Next mods for me is an all metal hot end, and try and work out why my speedo mount won't print in ASA been at it 2days and binned 6 prints do far. Going to mix some ASA with acetone tomorrow see if I can get better adhesionhave you considered direct drive feeding? my kit came with it so I haven't used the Bowden cable feed set up at all. the kit on mine is the same as for yours. mounts the extruder directly on top of the hot end. looks like this
only "problem" ive had is that the filament lightly scrapes the side of the extruder and makes some dust. that's because the roll is mounted on the side of my cube frame and the filament comes in at an increasing angle as the carriage moves. with your enclosure (and the one im making for mine), you could place your filament roll on the top and feed straight down to the extruder. that's my plan, to help reduce the amount of width the printer takes up in my room. I have vertical space but not so much the other directions...
