I am configuring my Duet2 Wifi with a BLTouch and am having some issues. I've looked at most of the guides and troubleshooting guides with no luck.
Probe will do a self test and pass. When I run either the deploy or retract gcode nothing happens. Probe also doesn't deploy when trying to home z. PWM is plugged into Duex PWM 1
Here is the config code I am using.
; Z probe and compensation definition
;*** If you have a switch instead of an IR probe, change P1 to P4 in the following M558 command
; IR PRobe - uncomment the following 2 lines if you have a and IR Probe, and comment out the BLTouch section below
;M558 P1 X0 Y0 Z1 ; Z probe is an IR probe and is not used for homing any axes
;G31 X0 Y30 Z2.00 P500 ; Set the zprobe height and threshold (put your own values here)
;BLTouch - comment out the following 3 lines if using a IR Probe
M307 H3 A-1 C-1 D-1
M558 P9 X0 Y0 Z1 H5 F50 T6000 A5 S0.02
G31 X2 Y42 Z2.65 P25 ; Customize your offsets appropriately - do a paper test, and put the probed value in the Z value here
M561 ; clear any existing bed transform
G1 Z5 S2
G30 P0 X15 Y45 Z-99999
G30 P1 X15 Y275 Z-99999
G30 P2 X275 Y150 Z-99999 S3
G1 X0 Y0 F5000 ; move the head to the corner (optional)
;G30 P0 X30 Y45 Z-99999 ; define 4 points in a clockwise direction around the bed, starting near (0,0)
;G30 P1 X30 Y215 Z-99999
;G30 P2 X225 Y215 Z-99999
;G30 P3 X225 Y45 Z-99999
;G30 P4 X125 Y125 Z-99999 S0 ; finally probe bed centre, and calculate compensation
Deploy Probe Using M280 P3 S10
Retract Probe Using M280 P3 S90

post a picture of the wiring.
also double check the wires, there are a lot of reports of bad extension cables.
here is a pic

you have gnd and signal swapped.
I switched it and still having the same issue.
Which firmware version are you using?
I think you have the 3-pin connector reversed in the PWM connector. AFAIR the brown wire is ground, which is the rightmost pin on the DueX PWM connector. That would explain why deploy/retract isn't working.
