Hi Lefferocker,
Never heard of this control. What kind of machine is this controlling, mill or lathe? Do you know if the G-code set is standard EIA format? If so, a generic post processor should work. You can then start writing FIL code to get what you "want". I'm interested in hearing/reading what this "thing" is.
I checked my Post processor library and i don'find it, but Fanuc hasn't changed much in their syntax as far as I know. If you have a fanuc generic post it's really simple to modify one to make your own postprocessor.
