ToolChanger Z home

Hello,
I assembled my new toolchanger and upgraded the firmware of duet 2 ethernet.
Now I can home XYC but not Z. What I have to change in the settings?
Thanks a lot.

 

I installed firmware 3.1.1 on the duet

 

FIRMWARE_NAME: RepRapFirmware for Duet 2 WiFi/Ethernet FIRMWARE_VERSION: 3.1.1 ELECTRONICS: Duet Ethernet 1.02 or later + DueX5 FIRMWARE_DATE: 2020-05-19b2

M98 P/macros/Coupler - Unlock ;Open Coupler
G91 ; Relative mode
G1 H2 Z5 F5000 ; Lower the bed
G90 ; back to absolute positioning
G1 X150 Y100 F50000 ; Position the endstop above the bed centre

G1 Z5 H1 F1000 ; Move Z down until the switch triggers (first pass)
G4 P500 ; wait 500msec
G1 Z5 F5000 ; Lift Z
G4 P500 ; wait 500msec
G1 Z5 H1 F300 ; Move Z down until the switch triggers (second pass)
G4 P500 ; wait 500msec
G1 Z5 F5000 ; Drop the Bed
G90 ; Back to absolute positioning

 

I just changed "Z" positions because it will crash in to the head

 

Now I could manage it somehow. But it is not possible for meshbed levelling.
Here my config.g
