Great idea, I think I can see a few changes that we can make to the gearbox to incorporate this.

I would just use a spacer between the two gears (that goes through where the bearing is currently located) and then put your encoder on one of the outer ends of that shaft.

Thanks for the suggestion, we will look into implementing it.
