Minor update..
Tested the sketch again with motors actually attached to make sure i had the pins assigned correctly to suit my specific wiring -All good, commands work as expected - Motors turn, change speeds and stop.
I'd been pondering using some of the inputs for a push-button controller - Its not at all hard, just more wires and components and logic in the sketch that i think probably is not needed right now - And i should be able to get the same functionality out of most of the software clients anyway. If i added it, the main issue would be "when do i ultimately decide what takes precedence"
The main things preventing me from testing are the clouds, and my homebrew autoguider setup (finderscope and camera) - Its quite hard to pick up any stars with it. I'm tempted to try print up an interface to connct one of my other prime lenses (135mm or 50mm, M42 thread) to the webcam and see how i go.
I think i need to bodge up a temporary cable to connect the DIY stepper for testing. Once i know everything works, i'll print out an enclosure for it all that can mount somewhere convenient
