Me again. If you have 8 wire motors then take a look at this: http://www.xylotex.com/PacSciIB.pdf
By the way, you are using a Xylotex board right?
I have bought 3 motors and I haven't found any information on which wire is which so far. They are 8 wire Unipolar Bipolar motors. How can I find out which ones are ground and step and direction? For unipolar what are all of the wire possibilities. Eg. Ground, Step Dir, Step Dir, for one motor?
I have some wiring diagrams for the Pacsci Powermax II, octagonal case motors motors to the site's gallery. The wiring concept is the same for all 8 wire motors. They may be useful to you.

The color codes and shield drains relate to the particular wire I use in the cables that I make. Be sure to not be misled by the color of the outputs, just 'follow the lines' to build with your own cable.
Maybe this link could help you, it's a complete tutorial about stepper.
I have see another simple tutorial to determine what cable does what on your stepper but I could not find it.... I will search and let you know if I find it.
