Generic NEMA 23 printed axis
thingiverse
Hello Everyone! I made a NEMA 23 sized version of my Generic printed axis. I'm currently using this for the Z-Axis on my CNC mill. It's Rock-Solid. I use 8mm rods and LM8UU Linear bearings in the slider. Instructions I posted the coupler I created to attach the NEMA 23 motor to the threaded rod here: http://www.thingiverse.com/thing:41003 Parts List: Small section of rubber tubing to go over the threaded rod. 608 skate bearing 5 mm x 25mm long bolts + nuts 1/4 threaded rod + matching nuts 8mm or 5/16 rails, 4x lm8uu linear bearings anything else I forgot to mention... Assembly should be fairly straightforward, The only tricky part I encountered was aligning the threaded rod through the nut on the underside of the slider. Make sure the indentation of the nut on the bottom section of the slider can fit the nut properly. I used a dremel-like tool to clean mine up so everything aligned properly.
