M6 and Manual Tool change

I have a "M6 T1" generated in my gcode file by Freecad.
I use only one tools...
And when I launch the file .ngc with a LinuxCnC Sim I get a pop up telling me to put the Tool 1
But when I launch thesame .ngc file with the LinucCnc "real conf with the cnc attached" I don't have this pop up and the linuxCnc does not start.
If I remove by hand this M6 T1 the engraving work.

I should have missed some configuration in the hal or ini file?
Any Idee?

Manythanks

 

Have a look at usage:

linuxcnc.org/docs/html/man/man1/hal_manualtoolchange.1.html
 

Thanks
So if i understand I just to have to add in my hal file theses few lines :
loadusr -W hal_manualtoolchange
net tool-change iocontrol.0.tool-change => hal_manualtoolchange.change
net tool-changed iocontrol.0.tool-changed <= hal_manualtoolchange.changed
net tool-number iocontrol.0.tool-prep-number => hal_manualtoolchange.number
net tool-prepare-loopback iocontrol.0.tool-prepare => iocontrol.0.tool-prepared

Is there a specific place in the file or anywhere will works?

In my hal file this lines are at the very end

Thanks
