I printed my first (really screwed up) calibration cube this evening! However, as it fed filament in it would make a loud clicking noise and I could see the small extruder gear almost bouncing while it rotated through its cycle.
In the build instructions you say to make sure the hobbed bolt and large gear spin freely. I hand tightened the bottom nut initially and when I went to look at it it had spun completely off the bolt. I think ratcheted it down fairly tight, but I could still manage to turn the gear by hand. The large gear is now right up against the bottom of the main extruder assembly and the motor is still having trouble turning it. Would a washer between the gear and bearing help with what appears to be binding?
I'm hoping the problem here isn't that the motors just aren't strong enough, but I'm afraid that's what it is :/
