Home all button no working

Hi
I have a four axis setup with no home switch on the Z axis. It is not displayed either. I can home the axis individually with the buttons but not together with the Home All button.

The code does not execute either but with no error message or warning.

I have a four axis setup with no home switch on the Z axis. It is not displayed either.

What is not displayed?

However, I can confirm that the fourth axis is not homed when pressing home_all.
I tried with the XYZC example configuration.
There it is neccessary to press Home C to have all homed.
But it prints some debug information:

The Z axis is not displayed as the machine does not have a Z axis.

Ah, you mean you have a home button for Z even though you don't have a Z axis (and no DRO for Z?), right?

No if you hide the Z axis there is no button for that.

The reason seems to be that if you do not have HOME_SEQUENCE = 0/1/-1 specified, the home_all will not home any axis.
