The drivers you have are for servo motors with optical feedback. They won't work with stepper motors.

Steve and the gang,
Thanks for all the help with the parallel port to driver interface connections. Now that I have a harness built for the computer parallel port interface, I am ready to wire the motors to the drivers. I have two unipolar six wire steppers p/n 57BYGH405A and two CW260C drivers. The color code on the stepper motor is A=RED, C=GRN, B=YEL, D=BLU and the coil center taps are black and white. The drivers have six connections on the power side labeled: <DC70V/VCC, GND, A+, A-, B+, B-. Which wires on the driver go to which wires on the stepper motor.
Thanks DiBo

Hey, Paul whats up? I bought the stepper motors and drivers from the same place and they recommended one should be used with the other. The print on CW260C calls it a Microstep Driver. How can I find something that will work and have a wiring schematic that makes sense?
Thanks DiBo
Driver sounds like bipolar driver.
You can connect the motor like bipolar, leave the center taps disconnected, or half of each coil.
Do you have some instructions or data sheets that you can post?

Nevermind, I found some info. Not 100% sure, but I think its:
A+ = Red
A- = Yellow
B+ = Green
B- = Blue
However, looking at a data sheet for your motor (and a poor one at that), it looks like the Yellow is one of the center taps???
I'd recommend calling the people you bought them from and ask them how to wire them. Looks like Circuit Specialists?

Hey guys, I have everything hooked up and tried to run my steppers with a shareware version of turbo cnc through windows 2000. I believe all my wiring is correct to the parallel port and my drivers, but nothing works. The driver is a CW260C and the steppers are 57BYGH405A. The thing I am unsure of is what is the purpose of en+ and en-. I wired both drivers en+ to pin 1 of the parallel port. From what I have been able to learn pin 1 from the parallel port is a strobe. I don't know if that has anything to do with why nothing works. The voltage at cw+ and cp+ is 2.9vdc constantly and the voltage at en+ is 2.7. If i remove the wire from either driver en+ a sound the motors sound like they want to move but don't. I am frustrated and I wanted to just quit, but now it has become a challenge to learn more so I will not accept defeat.
Thanks DiBo
TurboCNC will NOT work in Win2K. It can't get the needed access to the parallel port. It will work marginally in Win98, but really should be run in plain DOS

en is probably enable
cw is probably direction control
cp is probably the step control
en will probably need to be wired to a pin that will be high while operating the steppers or fixed to a high level.
Hello John and all the rest. I know this is an old post but no one has posted a great reply yet.
57BYGH405A from http://www.circuitspecialists.com/pr...57BYGH405A.pdf
CW260C also from Circuit Specialists.
I have both the same motor and the same controller and they are not the easiest to work with.
Here is what I did to get them to work.
Red to A+, Green to A-, Yellow to B+, Blue to B-, White and black connected together.
