I am pretty darn clueless when it comes to electronics and code so, I’m hoping for a bit of guidance with this project. I am moving away from the DC motor I’ve been using on my portable star (barndoor) tracker because of the pains of constant adjustments to achieve the needed (accurate) 1 rpm. Anyway, in a perfect world, I would like to have the stepper motor I ordered run at a constant, smooth 1 RPM in one direction. That’s all it has to do, just on or off.
I am now searching for the correct wiring and code needed to get me going. I have found the basic wiring diagrams but I’m unclear as to set up for micro stepping if that will assist with smoothness.
If anyone has ever run a stepper this slow or can otherwise assist with any insight, it will be greatly appreciated. I have much to learn, this is a new world for me
(fwiw I’m a mechanical tech by trade (25+ yrs) and soldering is not a problem for me)
