Homing Alarm 11 Not Asserted Following E-Stop

[engigeer]

I encountered an issue when homing required is enabled. It seems that Alarm 11 is never asserted following an e-stop with loss of position, but the machine remains in an Alarm state until the homing cycle is run. There is a message reported that homing is required, however these messages are not always visible (i.e., if I am operating the machine from a pendant / controller that only reports Alarm codes).

I'm thinking instead perhaps it would be better to mirror the handling case where homing is required but only some axes are homed.

	sys.alarm = Alarm_HomingRequired;
	state_set(STATE_ALARM);
	}
