I got a bunch of ballscrews pretty cheap from an auction. They range from 15mm diameter to well over 2.5" in diameter.
The two I had in mind are brand new German STAR screws.
One screw is 84" long and has something like a 50mm diameter.
One screw is around 72" long roughly 50mm diameter. Would make a hell of an X axis (nuts)
TOTALLY overkill for a home cnc machine.
Can a run of the mill Keling servo motor (maybe the 1100oz) even turn these puppies?
I'd like to try and use 1, maybe toss the other on ebay
