$H on the other side always tries to home all axis.
Yes, but according to the homing passes defined by $44-46, each pass can home a single axis if so configured. If a pass fail the sequence is exited.
This means, the controller is only homing Z, stops then and sets the status of all axis to homes (which seems like a bug to me).
Yep - it seems like it does if you try to home X and Y at the same time and both are auto-squared. An alarm should be raised? Or returning an error is better?
Ty for the clarification. I must have overlooked the homing cycle setting.
I think the way you have done it now is perfect. This way users will get feedback when their configration is wrong (like mine) 👍.

The function noted above says it only can home one auto squared axis at a time. $H on the other side always tries to home all axis. This means if I have an X and y axis with auto squaring enabled there is no way I can use $H for homing. Is there any particular reason why the function does not support it ?
Furthermore I'm also confused about the return Boolean return value. It actually returns false in this case, but the calling function (mc_homing_cycle) doesn't set any alarms. This means, the controller is only homing Z, stops then and sets the status of all axis to homes (which seems like a bug to me).
