    Can any one offer any advice on what ball screws to go for for the x y and z axis?
    was thinking of running two screws on the X linked by belts

    many thanks
    When you are in front of the machine X is left right, Y and A are the long axis. Its called "the right hand rule"

    So on your question, i will always prefer 2 motors each belt driving via reduction or not the separate ball screws, versus 1 motor belt driving both ball screws at once. While second is a fool proof way to do it, its more difficult to set up, dust protection will be needed for the belt, motor and drive have to be more carefully matched to the machine. Plus tension to the belt must be right to function properly and there is more possibility for misalignment. In other words i choose the simpler way to do things. So at the end of the day= there is no better way. its all the same if done right. The result i mean.

    PS. Also comes to my mind that the one motor design could not be 100% suitable for very fast and heavy machines say 20-30 meters per minute and serious acceleration. Not that there are such in the majority of the DIY builds. Its one thing to put much pressure on 300 mm belt and another on 3 meter belt
