G-Code error in ncam.ngc Near line 100 only Facing

O-sub not found can be caused by wrapping the file in % signs rather than ending with M2.

It's not that is it?

Hi Andypugh.
I have test it before search because i was thinking that this is really juste a problem like M2 or %..but even if i edit the file and change M2 that nativecam have put or % i have always the same errors when open the file..

It would seem odd if NativeCAM (written specifically for LinuxCNC) does not produces LinuxCNC G-code (as was suggested a few posts back)
