Touch probe et plate sur la meme entrée was created by Philippe
Bonjour a tous,
je désire mettre une touch probe sur ma CNC, j'ai deja une plate probe pour la mesure automatique de la hauteur de l'outil,
quelqu'un c’est -il comment faire car sur ma carte beak borad je n'ai qu'une seule entrée , ainsi que le le paramétrage du HAL.
merci de votre retour.

"Hello everyone,
I want to put a touch probe on my CNC, I already have a flat probe for the automatic measurement of the height of the tool,
someone is it how to do because on my card board beak I have only one entry, and the setting of the HAL."
I'll get you the HAL settings that I used when I get home tonight unless someone provides the info sooner.
Here is a link for the hardware side of what I made.

I'm not sure I fully understood your question. If you are trying add a 3D touch probe I can't help with that but if you are trying to get the probe you have to measure tool length then here is the info I have. I am not the original author. I found it on a forum, probably here. I am using Mesa cards and you will have to change the hardware pin names to those appropriate for your machine.
Good Luck

Thanks to your answer,
Yes I want to add 3D touch probe with a touch to measure the tools on the same input if is possible because on my breakbord there is just one input for the probe and in linuxcxnc configuration.

Oui, c'est possible.
Wire the probes in series into the same input (assuming that they are both normally-closed and open on contact)
