Sorry Geoff, I can't see 2 steps per sec. at the eyepiece at 212X..? My eyes are'nt that bad either. I've also read that, but I've just busted that myth!? and I'm not sure how or why!
I'm one happy chappy!!
I just GOTTA thank all you guys on here that helped with advise etc!
Namely Laurie for the controller plan. Raff at AOE for building the controller. a 1980 something electronic typewriter for the stepper.
My wife for putting up with my foul moods when the last 1/2 dozen designs failed.
And you Davo for being just as chuffed at my success as I am!!
