Yes, could live with a bit of backlash but not that much, the Z is great, less than 0.005mm from what I see and even the knee only has 0.03mm or so in the bevel gears. Fitting new balls in the X and Y and then making new shims for the ball nut spacers probably would have reduced the backlash to acceptable amounts but when I found ground C5 ballscrews for £240 delivered, I decided it wasnt worth it. I do plan on reusing the X axis screw for the tailstock on the lathe so may have a go at reducing the backlash in it just to see even though it wouldnt matter for a tailstock as the quill is hydraulic it just need to get within +-90mm LOL.
