Exodus,
Just one point that's important - Check that your existing steppers can be operated bipolar (that the have 4, 6 or 8 wires and NOT 5). The cheap Chinese boards are almost all designed for bipolar operation of steppers.
This attachment is pretty typical of a single board instructions and may be of interest to you.
Good fortune with your project.
