I try to explain myself,
1 open the script I select gcode mach3
2 opens the list window (and is empty)
3 close
4 open a file from mach3 gcode charge then I close it
5 reopen the script I select gcode mach3, now in the list I find the file opened previously, only that even if there are other files.
the jobs \ gcode section works well

---the jobs \ gcode section works well

you mean "GCODE LAVORI" ?

are you sure the files are in C:\mach3\gcode ?

because here it works

yes "GCODE LAVORI" works well
I attach pictures to explain better, those on the list were opened first with "CARICA GCODE" FROM MACH3

Looks like i has something to do with your file attributes (see Picture)

can cou cross check with gcode lavori files ?

I tried to change attributes the problem remains
if you delete the files (c; \ mach3 \ gcode) in the selection screen the file names remain

create a Folder C:\mach3\test
copy a couple of files there
Change the path in the macro
test again

after many tests at the end I deleted the folder "gcode", recreated the folder inserted files and everything started to work !!
THANKS FOR YOU'RE HELPED TPS !!
