Unfortunately the extruder gear on the printer is unique, but if it could be reused then that would be sweet. Reuse of that gear may be a way to solve both the ratio and backlash problem all at once. I think the best aspect of direct drive type I’ve seen on other extruders is the tension capability that we do not have with the cube 3 native design and as a result it seems our printer is intolerant of slight variation in filament thickness. I’m operating under the assumption that the main flaw is the need for tension, and that the gear won’t wear out (it may eventually wear out).

I think you’re going to find the challenge is coupling to the square drive on the motor to any hobbed gear. But thinking through this a lot of people make their own hobbed gear with bolts.

Good luck, and keep us posted.
