    The Z-axis has been causing me some concern. Do you think there could be a racking issue?
    I had thought about putting the ballscrew in the centre of Z-axis pillar with a motor on top but that means either putting a slot nearly all the way down the z-axis pillar which I thought may weaken it too much?
    Or making the z-axis twice as long, keep the same amount of travel and put the slot in the top half - this makes a ridiculously long axis.
    Or I could add another ballscrew to the other side.
    What are your thoughts?
