text: stepper motor driver card to control 6 stepper motors...? hi,  i am looking for an external card to control 6 stepper motors concurrently.  ideally, i would like to pass commands from computer using rs232  or usb.  the motors are small and will be used to turn light gears clockwise/anti-clockwise.  thanks in advance for your answer. regards, how about 3 - 2 axis cards with rs-232 inputs?  http://www.applied-motion.com/products/stepper/drives/2035xd.php  you also have to buy a driver/amplifier for each motor.
