        @remixbot Ok, that seems to be wrong.

        You might want to adjust position of homing point changing line with:

        G1 X5 Y5 F6000 ;go to first probe point
        

        BTW - did You use configtool, and set bltouch there? it generates proper config files.

            but can't seem to wrap mye head arround the pin assignment i config tool.
            Pin Assignment
            Input Pin
            zprobe.in
            Modulation Pin
            zprobe.mod
            PWM Control Channel (BLTouch only)
            exp.heater3

                  Is BL Touch deployed, but bed not detected? Or not deployed at all?
                  Describe what and where You connected (from BLtouch).

                          @remixbot said in Having problems with the bltouch, duet 2 wifi:

                          G1 H1 Z-205 F360 ; move Z down stopping at the endstop
                          G90 ; absolute positioning
                          G92 Z0 ; set Z position to axis minimum (you may want to adjust this)

                          To use the probe you need to use G30 as shown by BoA in his example homing files.

                          If your wiring is correct and the config uses those correct pins and it still doesn't trigger but the servo commands work, then it's likely a bad connection on the white wire, which is the trigger signal.
