If you've matched small corners to small faces & large corners to large faces, It sounds like your cube pins may have turned out too long, pushing the gear pieces too far away from the center piece. In my case, I found that the key to a smoothly working AGCG was tuning the length and thickness of the pins to better match what comes out of my printer. You can use your host software to scale the cube pins to a shorter length by unlocking its' XYZ scale lock, and just shortening the long axis by several %, say from 1 to 0.96. I ended up printing a number of experimental pins until arriving at the optimal pin size for my printer. It's worth the effort, your cube will turn out silky smooth.
