I got a wild hair up my butt to build a machine and thought I'd post a few pics of the progress so far. It's about a 4' x 4' foot print, all aluminum build. I'm stuck on the Z axis mount right now but when I get some time this weekend I'll figure it out. The gantry is heavy so I may need to beef up the motor to something stronger. I'm going to use steppers that are approximately 300oz and use 1/2-10 acme. It's my first build so I'm not too worried about ipm right now. Let me know what you think.
