I believe what VMAX refers to, is the proper selection of a component . . . .
That is my question. How does one go about selecting, identifing, determining a 'well engineered' component. A statment was made, I'm just asking it be expanded to a useful point. Exactly how does one go about matching these components together as you correctly point out must be accomplished. I see a recurring contradiction whereing stepper systems are consistently touted as being 'easy', 'uncomplicated', etc, yet there is a never ending stream of posts with 'missing steps' or something similar as part of the subject line and then a pile of shot-in-the-dark suggestions on how to diagnose the problem. Not unlike this very thread.
Therefor, the logical conclusion is that this is not so simple as it's made out to be.
It's a serious question. I've done a ton of research on these topics and I don't reacall finding any clear advice on exactly how to select a 'quality' component from the vast choices available in the world of steppers. i.e. is it all down to getign a consensus or recommendation from existing users, or is there some way to be proactive in interpreting a spec, graph, or other perfomance documentation?
I.e., starting with a clean sheet of paper, what are the caveats to avoid and what is a logical path to sucess in setting up a stepper system. I'm asking for the benefit of the OP and others, as I am not planning to use steppers again.
