Z probe not activating home

[ronnien58]

I am using the Duet WiFi:
Firmware Name: RepRapFirmware for Duet WiFi
Firmware Electronics: Duet WiFi 1.0
Firmware Version: 1.20beta8+1 (2017-11-18)
WiFi Server Version: 1.20b8
Web Interface Version: 1.19.3
The probe is set up:
M558 P5 ; Use a simple modulated Z probe
G31 P1000 X-25.5 Y0 Z0 ; Set the probe height and threshold (put your own values here)

I get the out put under Z probe: 1000 however it does not stop but continues down.
I am using a proximity sensor that has always worked not sure what is going on.

Thanks DC, I found my problem. I had the HomeZ and HomeAll configured wrong for the Z axis
