Clean design, great source code. Even has information about the one-way communication between the hand-controller and the mount, something I've been unsuccessfully trying to figure out.

I mounted D15 connector for serial and/or paralel guider cotrol interface at the left of the metal cover between edge and other connectors.

I don't suppose you could elaborate on this a little? I'm having trouble picturing it.

You need two steppers, two gears (12 teeth, same modulus as used in the mount)

I wish I knew even the smallest bit about motors and gears, otherwise I'd be all over a stepper upgrade in an instant. So seriously, the $1000 GOTO upgrade is really 5x as expensive as it needs to be? I was under the impression they were especially heavy-duty to be able to handle such a load, but I guess the counter-weights are taking care of that.
