You can simply hook the coils of each motor in series like this heres one of mine driver cable comes in the top bluegreen, greypurple and motor cables leave at the bottom blackyellow, orangered. Can be used on ramps, rumba and other reprap electronics, but 8bit electronics usually are too slow for 164 and 1128 micro stepping. The gen4 stepper is designed to be compatible with both the gen3 and gen4 motherboards.
