    Hi,
    yes, your existing driver (Dm556) will work with that motor. Try it and see. I rather suspect that you will want a much higher input voltage (80VDC or so) to get your 34 size steppers to
    a good top speed. In which case you'll likely have to replace the DM556's and power supply eventually, but they will work in the meantime.
