What does CMM machines use in software

It might help www.govinfo.gov/content/pkg/GOVPUB-C13-7...a686274dfb3187ad.pdf this paper were writen by NIST(Same institute developed EMC) its use EMC(Linuxcnc's was once EMC)

Yes It is possible to create/add measuring cycle with G-Code by modifying the Linuxcnc interpreter but user program will not be a standard DMIS program

Ah, but, LinuxCNC supports pluggable interpreters. It would be straightforward (though a lot of effort) to write a complete DMIS interpreter for LinuxCNC. 

If you have an old, non-motorised CMM and just want a system to display and log the positions, then LinuxCNC could be a good choice as it has a number of GUI creation frameworks and can count encoder pulses (and other feedback types) accurately and reliably. 

I am currenlty working on an old Faro arm, and in that case I am just setting it up as a USB-HID device. Plug it into your PC and it will just "type" the coordinates into a spreadsheet or text file every time you press the button on the probe tip.

Oh! 

I wonder how far-removed that is from the LinuxCNC codebase? 

The "Canonical comands" that are listed look very much like the LinuxCNC ones that the G-code interpreter generates.

@andypugh i havent done any further study of code as right now busy with mine project but i found this document few days ago when want to build a poormans CMM for fun but its very very side project. and wish you all the best with your faro arm its seems quiet interesting pls update on forum or your youtube channel.
