thanks for your response ,
I am reassured that the problem does not come from me, I mechanic and computer is not easy for me, that 's why I make my program in gcode, it' s a language that I know.
I will try to find another solution.
I made this machine, a machine to cut the gears and I retrofit a fanuc milling machine.
i find linuxcnc genial, i have a mazak lathe and a cincinati milling machine, but linuxcnc is really the best.
regards
jf

There is a way to access a hal pin from gcode but I remember the documentation is in a very obscure place and I can't for the life of me find it for you

Thank you. I told you its obscure. Section 20 is actually a bit further down and is exactly what I wanted to share.
linuxcnc.org/docs/2.7/html/remap/remap.h...ap:referto-hal-items

So jf, by referencing the pin name that is connected to the motion.analog-out.nn you should be able to work with gcode variables you are familiar with.

The following variables should exist in your g code

#<_hal[pyvcp.diviseur]>
#<_hal[pyvcp.profondeur]>
#<_hal[pyvcp.Longueur]>
#<_hal[pyvcp.retour]>

So where you have

M66 E0 L0
#2=#5399 (_nb_division)

You might be able to replace it with

#2 = #<_hal[pyvcp.diviseur]>

And likewise remove the other M66 /#5399 commands and use

#4 = #<_hal[pyvcp.profondeur]>
#7 = #<_hal[pyvcp.Longueur]>
#8 = #<_hal[pyvcp.retour]>

I'm not sure that these pins will be there in a subroutine though so they might need to be passed as parameters to the subroutine.

Remove the spaces in the variable name in your gcode file and it might have a better chance of working :ohmy:
