Domo meets the world

Over the last year I've been designing and building Domo, my cnc milling machine.  He's currently on rev 4 and I'm finally satisfied with the design (my inner ocd disagrees but whatever). 

I determined the following constraints given my lack of metal working skills
  • Leverage existing components (8020 aluminum, pre-made linear rails, etc) 
  • Minimal manual milling (only 3 parts require high precision)
  • Easy to adjust and align
Below is the latest.  Perhaps I'll post some of his previous forms in the future.

A few features

  • Workspace: 55" x 29" cutting surface with 6" travel on the z axis
  • 381oz-in motors and Gecko g540
  • Bosch 1617 Router
  • Z axis

And a test run...
