I exported the CM G-code dialog to a text file (.gc), then fired up UGS. Homed my XXL, jogged to a mock zero for a job, loaded up the .gc, clicked "run" and then I got an unrecognized command "T6 M11" not recognized... hmm.
Not so universal.
I scroll to the top of my Notepad window, ix-nay this line (and the paran'd tool comment?), re-save the file and viola!
And, I get the ".egc" extension now (encrypted G-code).
Learning... off to hack a Triquetra connector of some-type for my controller and will try running that G-code collection. I really like the UGS "Return to Home" along with the animation and all the other HUD features that UGS has.
