nx cam post processor for linuxcnc 2.6.3

i'm trying to edit post processor with post builder for linuxcnc 2.6.3
which one is most close to g-code for linuxcnc 2.6.3 and easy to edit?
now I'm considering 2 start base for editing with default mill 3 axis in nx 9.0 and fanuc 6m.
here are g-codes from same object with different post processor.
structure is very similar but numeric display is different..
and
if you don't mind let me know which part should be edited.

thanks.

Hi,
even it's an old thread, the answer is really simple.
Output units are inch for the one and mm for the other post.
Hope this helps,
Thorsten
