    For this board I'm going direct to the driver chip but it will be useful to have the opto verision as well if you dont mind. Is it posible to do single steps with this circuit as well :whistling:.

    Thanks again

    Peter, seems to be ok when I look at it, dir pin is linked to the resistors
    Here is the opto version...

    Single steps I need to think about (and why would you want them?)
