Duet Maestro 2 Wifi BLTouch Issue

PUGCanada

I blue up my old Duet Maestro 2 Ethernet a few weeks ago by shorting out the mosfet for the heater. So I ordered a replacement and this time got the Duet Maestro 2 Wifi. I immediately upgraded the firmware to 3.1.1 since it was a new config build. The issue I am having is that the BLTouch is not responding at all. As soon as I turn on the printer the BLTouch is flashing red and the probe stays in whatever the last position it was in. The Z-Probe on the status screen always shows Z-Probe = 1000.

I have the wiring for the BLTouch hooked up to the dedicated 4 pin connector on the board. From front to back of the board, the BLTouch is wired as such:

White
Black/Brown
Orange
Red

In Config.g this is my Z-Probe settings:
; Z-Probe
M950 S0 C"^zprobe.mod" ; create servo pin 0 for BLTouch
M558 P9 C"^zprobe.in" H5 F120 T6000 ; set Z probe type to bltouch and the dive height + speeds
G31 P500 X0 Y0 Z2.5 ; set Z probe trigger value, offset and trigger height
M557 X15:215 Y15:195 S20 ; define mesh grid

Here is my deployprobe.g:

And finally, here is my homez.g:

G30 ; home Z by probing the bed

; Uncomment the following lines to lift Z after probing
;G91 ; relative positioning
;G1 Z5 F100 ; lift Z relative to current position
;G90 ; absolute positioning

The BLTouch worked perfectly when I was using it with my old Duet Maestro running old firmware but does not work with the new firmware. I have searched high and low to try and find out why it isn't working. Anyone able to help me out?

there is no wifi version of the maestro.

did you get the duet 2 wifi? the zprobe.mod on the 2 wifi is not pwm capable.

Exactly what I needed. Everything is working now. Thank you!
