Hi Dave
Your focuser has been great, but unfortunately I will not be using my telescope for while. We are moving house. Big pain in the neck and lower down. As I was packing up telescopes and my little workshop I come across small-geared stepper motor with PCB, ULN2003 driver, header and four LED’s that I got some time ago from eBay for couple bucks and penny dropped. It should be fairly easy to modify your kit to drive two focusers. You already got buffered header to drive three or four LED’s (can not remember if it is 3 or 4 I did not connected it on my kit) so it would be to sacrifice LED indicators for second focuser motor. I may be talking complete rubbish as I’m out of electronic game for about ten years and only PIC’s I been using were OTP type.
