    I think your latest design, but mirrored so that the Z-axis is mounted on to the same plate as the ballnut will be strongest:

    That way the spindle is closest to the Y-axis ballnut which should reduce flex parallel to the Y axis.

    Ok my stepper motor covers have arrived but

    the stepper motor has 8 wires and the plug for the cover only has 6 pins

    are all the wires require ??

    do I need to buy new plugs for the stepper motors

    Nah you only need 4 pins wires are joined in pairs so only 4 needed.

    The reason they put 6 pins in probably in case you're using a unipolar stepper driver as that requires six wires.

    Which covers did you get out of interest?

    It is as I feared, you bought the ones that 'will not fit the SY60 motor'. The motors you have are actually slightly bigger than Nema 23, so Nema24 ish...23 mean 2.3 inches, 34 means 3.4 inches etc...

    Maybe they can be modified. At least it looks like you only bought 2 not 4.
