Hi.
My Linuxcnc is 2.9.0-pre.
I have wifi relay module based on ESP-01S and written M1xx programs to manage it from Linuxcnc.
There is wifi is no matter, because works well, the problem is else.
When relay module is powered, my M1xx g-codes works and relay is toggled .
Problem started when module is not powered.
I want stop Linuxcnc in this case and no act with not working hardware.
In summary :
1. When module is powered all works as expected.
2. When module is not powered (or no communication), in MDI mode M1xx acts nothing at all, in RUN PROGRAM mode program ends in line contains M1xx, like should, but no message is given.
3. When I run program M1xx from terminal (it is executable bash script) message is given by display command from ImageMagick, as expected.
Some explanation :Program above turns on relay. Command curl gets http page from module, contained line with 'Relay is now: ON', it mean "all went well and relay is turned on", and program is exitted with 0 value. If get no page, it mean something went bad, and script display error message and exit with -1 value.
The program turning relay off is similar.
Why the output from M1xx is ignored at all, or works but not as expected ?

Some explanation :
#!/bin/bash
if ! curl http://192.168.43.11/RELAY=ON | grep 'Relay is now: ON' >/dev/null 2>&1
then
echo "M111 failed"
exec display M111-failed.png.
exit -1
fi
echo "M111 ok"
exit 0The program turning relay off is similar.

SOLVED !
I have trying with feh and qview, but the same effects.
I finally found - Linuxcnc losts the image file path.
You must give absolute path to image.
Now works as expected.
