Does it matter which version of Linux you use?

Thanks Andy,
Both versions now look the same on the Axis screen but I have managed to edit the G-code so that the simulation runs in Axis. Camotics had accepted and run the unaltered G-code.
I will attempt a cut of the altered file tomorrow.
If you are interested I have attached the original G-code It appears to have been fixed by deleting Lines 52 and 323 (322 after deleting line 52.
I am a little puzzled as to why those lines generate a circle and yet the lines that immediately follow them do not. Reading G-code is not my forte and at my age I am somewhat less inclined to delve too far into new coding although I suspect I shall be learning more about G-code, HAL and Python as this project progresses.
Cheers,
Paul
PS - why are .nc files not accepted as attachments?

its a little of topic as G-code talking
you can add nc ending to your INI

[FILTER]
PROGRAM_EXTENSION =

Thanks!
But I was referring to attachments that accompany posts in the forum here where the .nc extension is not acceptable.

the interpreter reads the G-code inside and "interprades the Letters"
the ending is not the Factor open TXT file will also work
