    Steve,
    Problem 2, can you get any tension on the floating end of the ball screw and pull it to get some tension on it ?
    I know you have double angular contacts at the drive end but if it's just floating over 1metre then it could be whipping,

    Problem 1, Give me a bell over the weekend, I may have a fix.

    Problem 2 - Yes John, I could screwcut the ends of the ballscrews that are sticking out on the x and y as I left them a bit long and turned them down to 10mm, how much tension will it need as I only have a normal bearing in that end. I could always change it for a angular contact though (just 1). Running at 3100mm/min on rapid at moment and the vibration go's away when its warmed up, could it be that beacuse the gantry moves so easily that there is no load on the ballnut? I can feel a very small amount of backlash in the nut if i get hold of the gantry and pull and push on it, and I mean very small amount.

    Problem 1 - Speak to you later.

    Not all R&D sees the light of day.

    Steve, battery on charge on the phone, try later.
