Homing, zero z-axis by button press on joypad.

First thing first, Merry Christmas to all of you.

I am new to LinuxCNC, I have a 3040 router and I bought a joypad.
I got the joypad configured. But I would like to be able to zero/home x,y,z and a Axis by simply pressing a button (or combination of two, but that I can handle). Same functionality like the Home button in the linuxcnc UI on the computer.
I can't really find a HAL function that would do this. Checked the AXIS, halui etc.
Would appreciate some help on this.
Thanks!

You can do a net MDI-zerox and connect that to an input from the joypad and then pass it to a halui.mdi-command-00. In the ini file under halui section, the MDI_COMMAND = G10 L20 P0 X0 for zero and G0 X0 to go to zero. Hope that gets you going at least!

Hi lamandesigns,

I tried your suggestion, but without luck. Linuxcnc doesn't want to accept gcode before I homed my axis, but homing is what I want to do. Chicken and the egg sort of problem.
But I found a way that works.
It is the halui.joint.2.home that needs to be set to home it.

I thought setting halui.home-all to be true homed all axes but I have not actually tried to use it.
