Want to upgrade your print-speed?
This is an extruder that allows you to mount a beefy, high-torque, NEMA23 stepper motor. You can directly attach it to the Bowden cable. With the Bowden extruder (see my other designs under the Thingiverse tag: bowden), the plastic throughput is your print speed bottleneck. Or should I say, was your bottleneck: With a NEMA23 motor I've been able to extrude more than 15 mm^3 of molten ABS per second. That's about a (fully solid) mendel in 22 hours! So now XY-movements are the bottleneck again. For this, I think I need to further reduce the weight of the carriage (lighter rods, etc.).
Usage:
You can simply press the Bowden cable with an M6 nut into the T-slot (to attach the extruder drive mechanism to the extruder head via a Bowden cable).
Note: An M5 nut will also work (for smaller PTFE bowden cables), it will be able to slide slightly, but its movement is constrained by the filament.
