    8 wire
    48v 12amp power range

    muddobber76,

    If you connect the steppers using bipolar drives you can wire them to use (4) four wires, that would simplify all your wiring, connectors, cables & plugs.

    Do you already have the stepper drives for this project?

    I don't have the drives yet but plan on Geko or Keling.

    I need them wired to obtain the most torque.

    muddobber76,

    1: Bipolar will produce the most torque.

    2: (4) four wire, wiring configuration is the only way you can connect to a Gecko or Keling drive anyway.

    Muddobber76,

    I like the high current capacity d-sub connectors.

    They are available all the way up to 30 amps.

    The 10 amp model will work with almost any stepper
    you can throw at it.

    Sounds like a driver issue .
    Although if your running a really old Mobo that could be an issue.

    You werent very specific with your hardware / O.S specs...

    Download the newest drivers from the motherboard manufacturer and see if theyll work.

    If this is an O.S install issue,you may have to slipstream your O.S install disk to add the appropriate drivers depending on which O.S your running .

    Google slipstreaming an operating system.

    Personally Id just use the Win 7 release candidate,its free and still good for another 7 months...

    Works fine for me.


    Also ,in the future start your own thread
