Helical milling with a diagonal repeat ?

As listed there, there is an M2 (stop) between the sub and the call, so the program just stops before calling the sub.

Thanks Andy. I think I missed an edit somewhere.
Now back to the problem of getting the "call" to work.

Have you seen wiki.linuxcnc.org/cgi-bin/emcinfo.pl?SubProgramFiles ?

That's a new one to me, Andy, and thanks.
I must be frank though. It looks like it will take all my liguistic skills to accurately extract the gold from the dross.
Why are so many pages of examples of coding written so poorly ?
The coding is probably perfect, but the language that surrounds it is appalling.

Good clue in that page.
I've now found the PROGRAM_PREFIX , nc files directory, so I should be able to make some progress.
Did spot a "Spiral.ngc" file in the examples folder, so I must watch that one.

In that case the original author was not a native english speaker, and then I hacked it about a bit to simplify it.
Perhaps a good proof that you have it all figured out would be for you to convert it to a more lyrical phraseology. The Wiki pages are all freely editable once you follow the instructions here: wiki.linuxcnc.org/cgi-bin/emcinfo.pl?BasicSteps
