Hey Randy,
Is your stepper hooked directly to the focuser of your edge or is it attached to a Crayford? Does your scope exhibit backlash?Set up TeamViewer and I'll run through your settings. Send me an PM with your cell/email address and we'll figure out a time to run through it.
SCTs are difficult because we need to measure the backlash so we can put that into SGP. Beyond that, we should be able to figure everything out.
Thanks, sorry you're having trouble. It helps to have a mentor for these kinds of issues.
Chris
