    I have built several machines using driver boards from xylotex. 

    Never mind that I hold an engineering degree, and various electrical
    engineering patents, purchasing that driver and matched motors was
    cheaper, and quicker, than building my own circuit. hystreresis, eddy
    currents, fourier inductive ringing, hexfet voltage spike induced
    breakdown, just keep all of those as fancy sounding phrases and buy a
    pre built board. you will save alot of effort, and get better
    control. 

    the boards are like $125-$150. 

    also, use stepper motors, unless you are building a large (weighs
    more than 1000 KG) machine. 

good luck
