The error message reported:

The problems is that when I send the halcmd command I get an error: "can't do that emc_task_plan_run in auto mode with interpreter reading"

indicates that an attempt to issue a RUN command (emc_task_plan_run)
was made which is consistent with using halui.program.run instead of
halui.program.stop.

Also, as mentioned, the code posted at message
forum.linuxcnc.org/10-advanced-configura...code?start=10#113013

Code:

...
case $? in
    0)sleep 3; halcmd setp halui.program.stop True

     sleep 6;
    ;;
esac
...

does not ensure that halui.program.stop is returned to
the unasserted (False) state (but it should using an appropriate
sleep delay).

You git has

USER_M_PATH = /home/ciccio/linuxcnc/configs/3040t_no-endstops/M-codes

But there did not seem to be a _no_endstops in the actual path.
But looking again, I think that depends on where you install the config.

Would it be better to poll for interp_idle ? (or a similar state)

OK, so maybe I have to use the timedelay component. Right? So, do you have an idea of how to properly write the M-code?

The method already posted at message
forum.linuxcnc.org/10-advanced-configura...?limitstart=0#112926

Code:

...
case $? in
    0)sleep 2; halcmd setp halui.program.stop False

    sleep 2; halcmd setp halui.program.stop True
    ;;
esac
...

will probably work

but just pulsing halui.program.stop is a little more straightforward and ensures that
halui.program.stop is returned to the deasserted (False) state:

Code:

...
case $? in
    0)halcmd setp halui.program.stop True
      sleep 2
      halcmd setp halui.program.stop False
    ;;
esac

I think that you can do the time delay in the M-code, but it might be more reliable to to use the oneshot component:

linuxcnc.org/docs/2.7/html/man/man9/oneshot.9.html

Then you can net the oneshot output to program-stop. This means that you can toggle the oneshot input off-then-on in your M-code but program-stop only sees a brief pulse that resets.

Code:

#!/bin/sh
halcmd setp oneshot.0.in False
(sleep 1 && wmctrl -F -a "Probe" -b add,above) &
yad --title "Probe" --image=/home/ciccio/linuxcnc/configs/10060_4th/M-codes/qs.png --geometry="290x120" --text="<big>Hai fatto il probe? Hai posizionato il mandrino in un punto dove poter cambiare l'utensile?</big>" --button="STOP" --button="Continua"

case $? in
    0)sleep 2; halcmd setp oneshot.0.in True
    ;;
esac
exit 0

The only drawback there is that the dialog box hangs around on screen for 2 seconds after you press the stop button.
