I just got to thinking that you could use an unused GPIO line to send a start/stop signal (using something like a coolant/mist/ or other line, and use it as a semaphore between two machines). In the distant past I wrote some CADCAM software that would adjust the part geometry based on touching off at the corners and finding the plain of reference. I doubt I still have that code though.
