    Ok... so all seems well... Y is working, Z is working. X however is causing me grief

    as previously explained X has two steppers... I have set X to be one, and A to be the other

    then in mach3 set A to be the slave of X

    Ive wired the stepper drivers in 'active low' so

    A-----------
    PUL(+5V) --- 5v feed
    PUL-(pul) --- PORT 9
    DIR+(5V) --- 5V FEED
    DIR-(DIR) -- PORT 8

    X----------------
    PUL(+5V) --- 5v feed
    PUL-(pul) --- PORT 3
    DIR+(5V) --- 5V FEED
    DIR-(DIR) -- PORT 2

    both steppers turn correctly... however I need to reverse one... so it kinda goes in the opposite direction to the way its presently going?
    doesnt matter which one...

    make sense?

    also, obviously im using a stepper controller for each stepper... cant I just use one controller for both?

    Just Change either of the DirLow active in Motor outputs and it will spin other way.

    Yes you can control 2 motors with one drive but not good idea because of the way they work and sharing pulse's etc, just don't do it.!!
    Also if your slaving motors you want away to control each motor for squaring the gantry and one drive won't allow that.
