Steppig with an arduino timer interrupt is ridiculously simple just using a

Just set steps to the number of steps to move and it will go.

Thanks Rod, that's potentially useful. an in motion tally and it would
be nearly complete.

So I need to hack up in hal. or maybe python, something that could take
a true or false signal and issue the correct steps/dir to position the
motor in one of two positions.
What two positions? Do do what?
The latest version of the carousel.comp can output stephen position
commands based on selected pocket.
But might be overkill for what you need, or might also be inadequate.
