Here's a mini 3in1 that has servos mounted to the three axes.
It is an evalutaion model for a company (Shoptask)to possibly market it.

The mill assembly ,although it looks nice, is full of problems. Each one of those aluminum collars that are used as guides for vertical movement are drilled differently so reassembly was a puzzle to get them right side up and in the correct location to align with the holes in the mill cross arm (or whatever it is called).
