Varios botones home

Hello everybody.

I would like to implement several home buttons on my machine, one with home at all 0 and another with the search for the buttons and another for the home of an axis.

Now I only know that you can have one of them, what variables should I modify to be able to obtain those buttons or axis files?

halui has all the pins you need to issue the commands.
So then the question is how to drive them.

Do you really need buttons? The Axis GUI offers "all" or by-axis homing from the Machine->homing menu.
