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.
