SOLVED Spoted a little bug on Z prob I think
when I home Z and the blTouch senor is allready triggered.
I get the message that the sensor is allready triggered and no z movement.
This is the expected behaviour, I hope.
What I think is a bug is that the Z change state to homed.
I think It should remain unhomed.
I use RFF 3.1.1, a Duet 3 and a blTouch.
And here is my homez.g
;Clear bed transformation N561 ;Goto prob position G91 G1 H2 Z5 F6000 G90 G1 X150 Y70 F6000 G91 ;Reset sensor M280 P0 S160 ;Rough prob M402 ; Retract prob M401 ; Deploy prob G1 H1 Z-305 F6000 M402 ; Retract prob ;Down 5mm G1 H2 Z5 F6000 ;Fine prob M402 ; Retract prob M401 ; Deploy prob G30 ; Prob M402 ; Retract prob
I agree, it should remain not homed. I will test this.
It's not a bug, it's because you are using the Z probe as an endstop switch in this line:
G1 H1 Z-305 F6000
That will mark Z as homed.
You should use a G30 command for that line too. You can use M558 to set the probing speed (F parameter) to a higher value before the first G30 command, and restore it to the usual value for the second.
@dc42 haha great I did as you said and by the way removed all those unnecessay M401 and M402.
Now it remains not homed.

Also I think your code N561 is wrong.
I think it should be M561: Set Identity Transform
@CaLviNx Thanks I didn't see this.
By the way it explain some weird behaviour I had in the past
