To be honest Mocha if your using a decent Cam package you'll probably rarely touch the G-code and even then if you do it will most likely be simple stuff like changing a feed rate (F Code) in G1 move or some thing like Z height etc nothing special or unique and mostly standard G-code on Most controls.!!

It's idea good idea to learn G-code so you can monitor and understand or keep track of whats happening while cutting but it's getting less and less needed has Cam gets better and Post processors become more refined.
