Again Mad Welder, thanks for providing the great information!
I am still trying to learn as much as I can about this whole process, but I am time limited with work and school.
Since I already have the ballnut mounts coming from LinearMotion, do you think that a preloaded double-ballnut configuration from them (or anybody else?) would be worthwhile (if they can provide one)? Or would I be better off going with a different brand of ballscrews and ballnuts, making my own ballnut mounts. I have seen a couple reports of high backlash numbers on the LinearMotion ballscrews, which is making me a little hesitant to purchase them.
I have been looking into double ballnut configurations lately which seem to help tremendously for backlash, and seems a little more fool proof on my end.
