G70 - 'Unkown G -Code used' error in 2.8.4

I wanted to try the G70 code after updating to 2.8.4 on my lathe using AXIS GUI.

I'm new to G70 so I wrote the attached program to see how it might work.

However, when I load the program LCNC tells me that there is an unknown G code used for the G70.

Do I need to do anything other than a standard install to get G70 working or am I coding incorrectly??

Sorry, but G70 (and friends) are not in 2.8.4.

They are in / will be in 2.9, which can be installed (but be aware that it is a dev version, so might occasionally break)

see buildbot.linuxcnc.org for how to install 2.9.

Thanks Andy
