MyDD - remix Bondtech BMG Direct Drive Extruder for CR-10 (Ender-3) Volcano Only

thingiverse

Update: January 17, 2020: Upload sample high-speed FFF profile for ABS. Great Mydd compact design. Mod: * Front and back part assembly screws with M3 nuts, 2 pieces. * Insert front and back parts with bottom lower screws using M3 nuts, 2 pieces each. * Two cable ties holes. This modification provides massive head-fastening stability. Inserted step file with all Volcano parts. This remix is only usable with the Volcano nozzle. I use Gembird ABS for printing: layer thickness 0.16mm, fill density 50%, print speed 245/110, acceleration 166mm/s, and acceleration compensation 3000 L.A. k factor 3. Very impressive high-speed printing!
