    X axis: 2 X 2010 ballscrews 1500mm long with 2:1 gear
    Yaxis: 1 x 2010 ballscrews 1000mm long with 2:1 gear
    Z axis: 1 x 2005 ballscrews 350mm long with 2:1 gear

    As for the speed calculations i have made this thread

    So with 2010 ballscrew and 2:1 gear ratio

    ballscrew length 1500
    ballscrew diameter 20
    ballscrew pitch 10
