Fostruder K4 - Dual Drive Extruder

thingiverse

Dual motor, dual drive bowden extruder employs two NEMA14 motors and two drive gears. The two motors must be wired to run in opposite directions, and can be connected either in series or parallel (it's recommended to wire the motors in series on a 24V printer and in parallel on the 12V printer). However, the specific wiring configuration will depend on the motors and drivers used. Two screws are utilized to adjust the gap between the gears. Alternatively, small springs can be employed for a constant tension setup. The following parts were used: * Two 0.8A NEMA14 Motors * Two Knurled extruder gears * One M5 Heat set brass insert * One M5 threaded bowden coupler (a similar product was utilized) * Eight M3x20 socket cap screws Additional information about several dual drive bowden extruders can be found on thrinter.com. This design was printed using Inland Translucent Yellow PETG.
