Why, on earth, do you want to take servo motors off, and
put steppers on????? Why don't you just update the machine as
it is? Are the servo amps separate units? Just keep them,
and hook to one of the servo control devices and use a
servo-capable control program. EMC and DeskNcrt can
drive servo systems. The Servo-to-Go card or my
parallel port axis control can drive most servo amps, and
read the position from encoders.

You can see some info about EMC and my parallel port
stuff at : http://pico-systems.com/EMC.html
and : http://pico-systems.com/PPMC.html

I can tell you, you will never match the performance of these
servo motors with any steppers!
