I purchased a Kit from
www.mydiycnc.com/ who have since gone out of business. It has been working well for three years and now one of the driver boards has failed. After some research I opted for a 3 axis TB6560 driver board from eBay. My problem now is which stepper motor wire connects to where on the board? I am using NEMA 17 stepper motors which have four wires, Red, Green, Black and Blue. I have the PDF for the board but am at a total loss regards wiring the motors. I have googled extensively for an answer but have drawn a total blank, hence my question. I am using Debian Wheezy if it helps. Yours in anticipation, Ian

It doesn't really matter which phase you call A and which you call B.
You can work out which wires are ends of the same phase by touching them together as you turn the motor by hand. If you have toucjed +A to -A or +B to -B then the motor will become stiff to turn.
Once you have the pairs worked out, connect them any way you like.
If the motor then turns backwards swap one pair (eg A+ to A- and A- to A+)
