    Haha you my friend are correct :)

    The only thing I got planned for 5v is the Bob and it's signals to the stepper drivers ( pul dir ena )
    I've bought a 5V 2A psu and still thinking about using it. If I were to use the pc psu I don't think I would connect usb but get 5v from a Molex harness. That way it's straight from the psu and not through the motherboard. If that makes sense??
