Is there any adjustment to the ballscrews?

[Dale Gribble]

Hi, I had the x axis motor off this weekend and noticed a bit of backlash in the ballscrew itself. I've got an ISEL ballscrew thats adjust's to take up backlash just wondering if this had any kind of adjustment? Another thought is if there is no adjustment, is that the screw looks multi start and if the ballscrew just uses one start maybe moving it onto an unused start. If anybody has more info on the ballscrews it would be gratefully received
