Setting up 360 to post for LinuxCNC

Hey guys,

So most of my machine is running and I'm in the testing phases (Just have a sharpie in the spindle drawing stuff on carboard) before actually cutting anything and I've noticed what when I post my G code from Fusion360 and move the NC code into linuxcnc I get (Unknown G code used).

Now I figured there was un-supported G codes so I checked the list of un-supported G codes and editing them out of the NC and it made no change. But If I delete the entire Top few lines of the NC it then works fine (For simple line sketches haven't tried anything more complicated) 

Example below;

So my question is really, why is this happening? When I was running mach3 I could just drop my NC program in like this and it worked fine, and two is there a way to set up Fusion to post on NC code that WILL run on linuxCNC or will i have to edit each program like this to get it to run? 

Thanks guys  

There is a Linuxcnc post in F360. It may be called EMC. I never had to modify anything.

Thanks Ill have a look. hopefully this is the case I have a habit of not finding things right in front of me

Yuhp I found it -_- Sorry guys

Thanks mate I am an stupid
