Ok, I've recently begun a cnc conversion project, and I got 3 bipolar steppers already. I need to find a controller and I'm fairly sure I'll be getting a gecko to handle the size of these boys. The motors are rated at 4.2v, 4.7a. nema 34. Anyway, I'm a total novice, and was wondering what the difference is between the g201 and the g210. Which one would be better for me. What does the more expensive 210 offer that the 201 doesent, and will that really matter to someone like me just starting out?
