I find it rather interesting that they seem to be using the exact same spindle motor that has been on the Hyrel Drilling/Milling head for about a year now. That said, I agree with awerby, even with a sturdier frame, we don't claim to make the Hyrel printers into a full-scale CNC with the DM1 head. To put it in the simplest terms, the features of a 3D printer are the flaws of a CNC mill.

I notice also that if the Z-Morph moves that tool up more than about 4 inches, it'll crash into the top support bar. Also, calling it a Hybrid implies that it can do hybrid additive/subtractive manufacturing simultaneously, which it obviously can't when limited to one tool at a time.
