Ok so i'm about to make a bigger cnc router, 24x24x6 travel will be using 287oz steppers and ballscrews. Am thinking of using skate bearings on chrome hardened steel 1" rods, the type used in presses.. my current cnc uses acme screws and bosch linear bearings, wonder how a 8 or 12 bearing skate would work. how is accurace / play in them was thinking about using 4 1/8" wall angles being joined with the bearings and possibly welded also. This will be an all steel machone 1.25" tube 1/8" wall, my current is in welded aluminum frame and i don't find it that rigid.
