OK

I always run from a terminal, because I use compiled versions.

Open a terminal, start linuxcnc from the command line, run the MDI command and watch the output in the terminal.

It should show up, you would get an error if the file was not found.

Yes, when M199 returned Successful in terminal when MDI command issued.

While open, I attempted the turning sub. The terminal reported " emc/task/emctask.cc 321: interp_error : File not-open".

Does this mean that the issue is in turning.ngc file?

No, I presume that the problem is that upon reading the o<sub> call, the file that refers to should be opened, but it has not happened.

I will have to dig out the code for 2.3 to see exactly what is happening, the line number is not right for later versions

regards

EDIT

Line number is just where the error is printed from, not where it occurs.
Possible cause as next post, the file cannot be opened for reading because permissions wrong

Does this mean that the issue is in turning.ngc file?

However, have you checked that the file is at least chmod 644, so that it can be opened?

In the file manager you can right click on the file and check properties and see if executable is checked or not. After making a change to the file like making it executable you will need to restart LinuxCNC.

Actually I just followed the example in the manual on 2.7 and the file does not have to be executable and can be created while LinuxCNC is running and it works. I did place the file in the nc_files directory.

I probably confused things by suggesting a test with a M code file (which does have to be executable) to check the PROGRAM_PREFIX works, then talking about sub files, which just have to be readable.

644 is read/write by owner and read only by everyone else.

Since the path obviously works, was trying to think of a reason why the file could not be read.

yes, i believe its chmod 644. i have attached the turning.ngc file
