@btj Try something like this:

config.g

; Z-Probe
M950 S0 C"duex.pwm1"                         ; create servo pin 0 for BLTouch
M558 P9 C"^zprobe.in" H5 F120 T12000           ; set Z probe type to bltouch and the dive height + speeds
G31 P500 X-50 Y-11.02                     ; set Z probe trigger value, offset and trigger height
M557 X15:215 Y15:195 S20                    ; define mesh grid

deployprobe.g

M280 P0 S10 ; deploy BLTouch

retractprobe.g

M280 P0 S90 ; retract BLTouch

If anything else isn't right, please explain what does not work.

@btj What do you get when you run M950 S0 C"duex.pwm1"?

@btj It sounds like you are still using RRF2, so it may be a good idea to upgrade to RRF3. If you don't want to upgrade, see https://duet3d.dozuki.com/Wiki/Connecting_a_Z_probe#Section_Software_setup_Duet_2_WiFi_Ethernet_running_RepRapFirmware_Num_2 for further instructions.

@btj Your config.g is a mix of commands for RepRapFirmware 2 and RepRapFirmware 3. Please send M115 and post response, so we can see what firmware version you are running. Then we can best advise you on the correct commands.

FIRMWARE_VERSION: 2.05.1

If you're not planning on updating the firmware to the current version (v3.3, but see update instructions here: https://duet3d.dozuki.com/Wiki/Installing_and_Updating_Firmware#Section_Updating_from_RRF_2_x_to_3_x ), then it will be easiest to regenerate your configuration files using the Configuration tool https://configtool.reprapfirmware.org/Start
This is because you have generated a configuration for RRF 3, see first line of your config.g:

; Configuration file for Duet WiFi (firmware version 3)

I expect currently none of your temperature responses will be correct, fans won't work, and there will be no tool, as well as the probe not working. All the lines in config.g that have C or P parameter with "[something in quotes]" will need to change, so it's easier to regenerate the files with the correct firmware version selected. On the https://configtool.reprapfirmware.org/General page, under "Firmware version:" make sure you select "2.03 to 2.05".

If you want to update to RRF v3.3, your existing config should work, but you need to tidy up your Z-probe configuration. See @chrishamm's post earlier.

@btj Have you made any changes to your config.g? If so, please post your current config.g.
From your earlier config.g, you will need to change your Endstop and Z-Probe sections. They should look something like this:

; Endstops
M574 X1 S1 P"xstop"                            ; configure active-high endstop for low end on X via pin xstop
M574 Y1 S1 P"ystop"                            ; configure active-high endstop for low end on Y via pin ystop

; Z-Probe
M950 S0 C"exp.heater3"                         ; 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

Remove these lines:

M574 Z[anything]
M307 H3 A-1 C-1 D-1
M307 H7 A-1 C-1 D-1 ; Disable the 7th Heater to free up PWM channel 5 on the Duex board.
Any other M950, M558 and G31 lines

Then post your config.g so we can check it.
