Well i will be using rolled ballscrews with a single nut for my CNC router. One thing that is appreciated, is that the backlash is constistent. THis means i can use software compensation. Or I might just buy another nut and make it antibacklash.
I know the accuracy is not nearly as great as some of the acme out there, but i think a lot of it comes down to what you want to do.
For my router, i am looking for speed and ruler accuracy, so the .004" per foot is fine |
