Keith,
The motors were already on the machine. I think they were sigma brand. The machine was a retrofit I helped someone do and the dirt bag still owes me money. Both of us were satisfied with the result, but my travel time should of been paid too.
Their 4 axis $395 stepper board said it is rated 45,000 pulses per second that is 2,700,000 per minute. Depending on how many steps it takes to move one inch on your machine this would determine IPM after diving it by your ball screw pitch and belt.
