@r3play one more question. it throws an error Error: Invalid servo index 7 in M280 command when probing the Z but i cant find any reference to the servo 7 in config.g or the homeall or homez. any ideas?

M307 H7 A-1 C-1 D-1 ; dissable heater 7 for bltouch

will do, thanks

@r3play Thanks for your help, youve been amazing. solved what i couldnt in minutes

@eldrad that did work, then it went back up and did it again... now to find the bit to move the y axis under the probe... then working out how to mesh level lol.

@r3play missed that bit. will trigger it again and leg it to the other room to press it in

@r3play It deployed the probe that time when diving so thats a big step forward.. but the y axis was out of the way so didnt trigger... now to find where ive cocked up

@r3play right thats enabled the probe up and down etc

@r3play Ive changed the pins to match the ones pictured. when i try and run the commands you listed it responds with
M280 P3 S10 I1
Error: Invalid servo index 3 in M280 command

@r3play As you have written they dont work.
M280 P7 S10 I1 ; Send PWM channel 7 the s10 (angle) command
M280 P7 S90 I1 ; Send PWM channel 7 the S90 (angle) command
M280 P7 S120 I1; Send PWM channel 7 the S10 (angle) command
M280 P7 S160 I1 ; Alarm Release and Push-Pin UP

The ones i have written above i have set macros for and they function ok. Looking at it i may have introduced a different p number on one or two things in testing from looking at other peoples guides.. wonder if that is a big issue

@R3play Thanks for replying. I have checked on my duet and it doesnt have a config-override.g. neither do the files i have downloaded from the reprap configurator to compare with. Is it something i need?
i dont know whether its relevant but the firmware details are below
Firmware Name: RepRapFirmware for Duet 2 WiFi/Ethernet
Firmware Electronics: Duet WiFi 1.02 or later
Firmware Version: 2.01(RTOS) (2018-07-26b2)
WiFi Server Version: 1.21
Web Interface Version: 1.21.2-dc42

Hi,
While i have been 3dprinting for a couple of years i havent done much fiddling until recently. I have recently upgraded my duplicator I3 v1 to run with the Duet wifi board in place of the old melzi. After much fiddling with settings it now works well (and amazingly quiet with the new drivers). I have now got a BLtouch probe which i have spend the last week banging my head against the wall to get it to cooperate. I have read the various guides and each seem to have their own spin on what ports etc to use and have tried a lot of them with no success. Luckily part of my problems were solved when i spotted on this forum a post about the cable not being right and checked the probe extension cable which wasnt in correctly. any chance one of you fine people could have a look over my settings and see where im going wrong ?
Config.g homez.g and homeall.g are included
The bltouch is plugged into H7 as per this guide https://betrue3d.dk/bltouch-on-duet-wifi-configuratio-and-usage/
Thanks in advance
