G7/G8: Diameter/radius mode around lathe
Selects whether lathe X coordinates are read as diameter or radius depending on the control.
For reference only: syntax changes with the control, the post-processor and the machine parameters. Check the official manual and run a simulation before cutting. Legal notice.
