Mirroring g-code group

[So not a Guru]

I have found conflicting info on the g-code group number for G50.1 & G51.1. Some sites call them as group 18 & some others call them as group 22.

Is there a standard someone could point me to?

The FANUC Manuals are THE standard. But Reader's Digest version is everything other than a 15 (0, 16, 18, 21, 30, 31, and 32) it will be Group 22.

The G-Code Lists are found in a few different manuals depending on the control and series.

I knew that they were one of the earliest implementors of g code in industrial NC equipment. But I thought I remembered that the old EIA had standardized it in the '60s. I assumed that the groups, at least, were standardized. Maybe Fanuc just matched them to the #4000 sys variables.

I'm  getting old and my memory doesn't work as well as it once did (reference the siggy)

Thanks James

I don't know that "groups" were standardized. Then again I don't know that they weren't

That's worth some further digging. I bought the APT Standard (ANSI NCITS 37-1999). A CAM vendor (NOT one of the big one) was telling me something I knew to be different than was being explained.

The actual G-Code "standard" is ISO 6983-1:2009. I don't have a copy of it. It's around $150. Not sure I can justify buying it.
