Re: Before I make a mistake, what do I need to know?

Chris, thanks for the advice that you gave me. I still have some
questions to ask.
The stepper motors that I was going to use where Nema 34, 2
degree/step unipolar ones. Since 1.8 degree/step is more common and
since I don't want to have to change motors in the near future, I was
wondering what would be a better choice for motors. Should I go to
the larger Nema 42 size. Would that give me more power plus speed and
what about the cost. And should I buy a true bipolar motor as opposed
to the unipolar ones.
Is 2 motors necessary for the X axis for accuracy and no binding, or
is 1 motor enough
Also, will a commercial controller, such as from Geckodrives, make a
lot of difference in preformance compared to a "home made" one.
