[Lab] Help choosing a stepper motor

[Michael Grant]

The easy driver is for bipolar only, it's a good choice for small steppers
(NEMA17).

There are many choices on eBay as well, about $11 will get you a serious
CNC driver for larger steppers (NEMA23).

What resolution and speed are you looking to achieve?
The mass you are rotating, is it heavy and will you require fast start and
stop?
