Re: Servos, Drivers etc.

Jon,
First thanks to all who have responded to my original post.
I would be satisfied with the 200 IPM.
Please explain more about 33K step pulses and how that could/would be
a limiting factor.
I plan on using Mack 2 on a Pentium III 733 computer running WIN 2000 Pro.
What would you suggest that I would require in the way of a power
supply? I figure that I would need about 10 amps./ motor?
Thanks,
Wayne
