It's just an X2, so nothing special. It has ball screws on all axis and it has 0 backlash as far as I can measure. I have spent a lot of time cleaning and adjusting it to make it perfect, so there is no slop either. I also have an ATC for it on the drawingboard. It's a 6 station tool turret mounted on the head of the mill. Will post a picture of the drawing at some point.
Will take a picture of it too at some point. It's sitting right next to our couch in our living room. (bor på kollegie). I'm also working on a PCB mill made from aluminium extrusions. I'm thinking of a way to make it more rigid, so I have to go to the hardware store tomorrow.
