thingiverse

Simple Bowden Extruder for use with genuine Bondtech and clone Bondtech gears on Wanhoa Duplicator 6/ Monoprince Maker Ultimate. You do lose 5mm of Y travel. Designed to work with the BondTech gears and clones. Bill of Materials: 1x BondTech extruder gear set 1x 7.5-9mm x 20mm x 1.2mm extruder/bed spring 6x M3 x 30 counter sunk screws 2x M3 x 16 Socket cap screws Assembly: 1. use a 3mm drill bit to clean out the holes for the mounting screws and the pin for the idler gear. Use a 2mm drill bit to clean out the path for the filament. 2. Mount the main body to the stepper motor with 2 of the M3 x 30mm counter sunk screws into the two lower holes. Installing the third screw blocks the mount hole for the extruder assembly. 3. Slide one gear onto the shaft of the stepper motor. Center the teeth grove on the opening of the filament path. Secure with a setscrew. You can use a small bit of filament to help align the gear. 4. Mount the motor and main body of the extruder to motion carriage of the printer and secure with the 2 M3 x 16 Socket cap screws. You can now install the 3rd M3 x 30mm counter sunk screw. 5. Slide the needle bearings into the second gear and position it in the tensioning arm and slide the pin into place. It should be a tight fit and self lock in place. 6. Place the spring into the deep cavity of the main body. 7. Slide the tensioning arm into place and slide in the final screw. You will most likely need to apply pressure to line up the holes and work the screw into place. 7. Be sure to change your e-steps. I've found that 135 to be the most accurate for the Fysetc BMG Clone gears that I am using. Be sure you save the setting change to the EPROM if changing via a control screen.
