Z probe not stopping z axis movement

Advenger77

Been printing for over a year on my HyperCube using adrino. Converting to DuetWiFi. X and Y are setup and homing correctly. Z though is giving me problems. I am using a Inductive PNP Sensor LJ12A3-4-Z/BY That i have used on the printer since the beginning. Sensor Zprobe is sensing the probe and switches from zero to 1000 at aprox 1mm to bed. BUT it keeps going and crashes into the bed and I have looked the Zprobe output is at 1000. Included is the Endstop configuration from config.g Any help would be appericated.

; Endstops
M574 Z0 S0 ; Define active low and unused microswitches
M574 X1 Y1 S0 ; Define active high microswitches
M558 P5 X0 Y0 Z1 H5 F300 T6000 ; Set Z probe type to switch, the axes for which it is used and the probe + travel speeds
G31 P600 X28 Y12 Z0.0 T5 ; Set Z probe trigger value, offset and trigger height and type
M557 X30:270 Y30:270 S20 ; Define mesh grid

Running firmware 1.20

1. Test the Z probe as described at https://duet3d.dozuki.com/Wiki/Test_and_calibrate_the_Z_probe.

2. If you are trying to home the printer using the Z probe, see https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCartesianPrinter#Section_Homing_Z.
