G-Code and M-Code Reference List for Turning
These are the common g-codes for CNC Lathes and turning. Code categories are the groupings for the g-code Wizard (type Ctrl+G for the Wizard). Function tells what the g-code does, Notes gives a little more information such as the parameters, and Tutorial is a link (if any) to a tutorial that uses G-Wizard Editor to teach how to use the g-code.
