Hi Magnus,

no, I didn't do any step count calculations. EKOS does this very well. Torque is not a problem with the 27:1 gearbox. Even with only 1mA at 12V there is more than enough torque for such setups. My camera is hanging upside down on the Newton and the focuser has no problem with it.
I bought the controller here: www.ebay.de/itm/132580666482 (20,12€)
