touch-off in joypad

hi there,
i need to grab the "touch off" button (in axis gui) on my joypad.
i'm a bit confused, because i can't find any hal pin connected.
how can i do it?

I don't think that you can, unfortunately.

What do you want to happen when you press the button? There might be another way to achieve the same result.

thanks for answer.
i would like the same function the touchoff button do: move the zero point of the loaded gcode on the XY plane, based on the tool position, and adapting the gcode position.
i also tried the G10 command in MDI mode, but it seems to move the zero point only. it don't move the tracks position.
after all, it's the same as the Z-probe do.
alternatively, could i grab the the keyboard's END key?

PS: sorry for my poor english

The touch-off button allows you to enter an offset, and that would be a more difficult thing to arrange.

If all you need is to set the current position to zero in X and Y then add this to the [HALUI] section Then connect the joypad pin to halui.mdi-command-00 in HAL.

You might need to force a reload/refresh of the preview screen. That is a different puzzle, and I can't recall if we found an answer.

it works. i was using a wrong gcode.
it doesn't refresh preview, but doesn't matter for now, i can do it manually in axis.
thanks
