Depends on the voltage. With 12v you can do 12mm/s or 28.86mm^3/s at 3500mm/s^2 accel without any real concerns on 1.75mm filament. With 24v you can go up up to 20mm/s with the same accel, but you'll want to limit the unretract or prime to about 12mm/s still. I can extrude at about 19.2 cubic mm / s with completely even sheen, but if I push it beyond 24 cubic mm it will have some shiny spby thews - Delta Machines
I'm definitely interested in testing your solution out. Does this cut down on resonance quite a bit?by thews - General
