File will not run in EMC

I have been advised that EMC requires a .ngc suffux to run a file. My attempts to run .nc files have been unsuccessful as I am presented with a "file will not open" message. If this is true is there a way to amend this? Please advise me. Thank you

The fugutuve file should be attached.............

HI

There could be a variety of reasons the file will not open, none of them to do with the extension

This screen shot shows that you can open a g code file with literally .anything as the extension, so long as you have permissions to open it and the file is a valid format for Linuxcnc

Putting PROGRAM_EXTENSION = .nc in the right part of the INI file should do the trick.

Seemed logical but in fact doing that threw an error in Axis at startup

Traceback (most recent call last):
File "/usr/bin/axis", line 2776, in <module>
extensions = tuple([(v, tuple(k.split(","))) for k, v in extensions])
ValueError: need more than 1 value to unpack
Shutting down and cleaning up LinuxCNC...

If the file has the extension .nc, where did you get it? What machine is it intended for?
You probably need to look at the contents of it and that the permissions are at least set to 744 (read/write/exec by owner, read by group/others)

regards

It seems there is a bit more to it than that. But not a lot more.
linuxcnc.org/hardy/dapper/index.php/foru...t=6&lang=french#6338

Finally tracked it down

PROGRAM_EXTENSION = .nc , .NC

produces the required result, the file appears in the file open dialog and will load

If you just put
PROGRAM_EXTENSION = .nc

Axis throws the error I pasted previously

Weird but can't be bothered to look much further, as selecting 'All Files' in the file open dialog would have enabled you to load the .nc file anyway

regards

OK, not weird, just poor programming.

The file was obtained from CamBam to be run on a Sherline mill with EMC installed. Thank you

I am still having difficulty with the file. This file was created in CamBam to be run on my Sherline. Please note that other files that I created using CamBam opened and ran without issue on my Sherline.

I have changed the .nc to ngc with no success. Selecting "all files" in the dialogue box allows the file to load, but I still receiver the same message "nested comment found" when I attempt to run the machine.

The permissions that ArcEye suggested were reviewed and compared to the sample files included with the Sherline (no changes were made)

ArcEye's suggestion of inserting; " PROGRAM_EXTENSION = .nc , .NC" confuses me as I do not know exactly where to install it.

I realized that it is poor etiquette and keeping with my poor programming practices ( I prefer not to do it this way ) I deleted the first 3 or 4 lines in the .nc file and the program ran. ?????????????

I wish that I knew what I was doing.

Please advise

And thank you.
