Re: Gear and motor problem
Check your 2mm key. That's the thing that prevents the gear from rotating on the CIM shaft.

The gear is held on the shaft with the retaining clip. If you don't have one of the retaining clip fingers in the keyway (the slot the key fits in), it's possible for the key to fall out of the slot. Once this happens, the gear does not move with the CIM motor shaft ... at least not as fast as the CIM shaft. Your motor will turn but your tough box output shaft won't.

If one output shaft is turning (assuming right and left motors) but the other isn't, your bot will turn.
