BlTouch not triggering, tried everything
I purchased the latest BlTouch but for the life of me can't get it to work. Got all the latest firmware that I know off.
Using the Duet 2 wifi.
Heater PWM 7 input
Everywhere i look it says something different so im really quite stuck...
attached is my config file, if someone could point me as to where im going wrong i will be so thankful!

post your retract and deploy script
1/ what version of the firmware are you using . try M122
( you are on version 3 of the config.g , but have you upgraded to version 3 firmware )
2/ Are you getting the red light and getting the in and out power on self test

You config is for the 3.xx firmware version.
YEP , you are running the version 3 config file , but still running version 2 firmware ..
upgrade to version 3 firmware or use the version 2 configurator
Ive tried upgrading to 3.0 but it doesnt seem to update the firmware... I used "duet2and3firmware-3.1.1.zip" and uploaded it

You need to upgrade to I THINK version 3 ? , then 3.1.1 .
I know you can't do it in one go !!!
Lifesavers!!! yes 3.0 first worked!
Thank you all so much... hopefully, it's plain sailing now!

The bits which you normally get it wrong is offsets ( G31 ) , Which you say is level on the X axis , but the probe is 40mm behind the nozzle on the Y axis ?
And how you home !!! You need to use G30 to home Z
Try G31 P25 instead.
