Stepper motors, encoders...
I'm a new guy wishing to build my first CNC mill. I aquired 3 450oz Superior Electric "slo-syn" stepper motors. Questions on encoders, should these have built in encoders? What should I look for? I also need a controller, is the 3-4 axis controller from www.hobbycnc.com something that would work with my motors? Also, if the motors are 200 steps/rev, where do I tell the computer what pitch the lead screws will be to get accurate results (is this what encoders do? I'm new).
Thanks,
Noah
