I was just looking at the ballscrews available at McMaster-Carr (to go into a planned very small cnc mill I am building from scratch). Originally I was thinking to go with acme thread and delrin nut, however ballscrews would make life easier for my possibly too small steppers.
When using the 5/8" diameter screw, with the correct ballnut what sort of backlash compensation is required? Should two nuts be used? I have worked out that I can buy all three axis from them cheaper than what I can get just the screw for in Australia which is why I am considering it.
Has anybody else got this set up running their machine?
