      You need to change the M307 line under Z-Probe and make sure the H value lines up with the heater number you have connected to the bltouch.

      For example, if you have the bltouch plugged into heater 7, change the line to the following

      ; Heaters
M307 H7 A-1 C-1 D-1 ; disable heater

      Then you will want to check the following files to make sure they have a consistent heater number in the M280 command as well.

      /sys/deployprobe.g
/sys/retractprobe.g

        M558 P7

        This should be M558 P9 for the BLTouch.

        I suggest you do some reading:

          @Phaedrux i was wondering if the deploy,and retract files look right.

            Do they work? Are you using heater pin 5? You may need to invert the command with I1

                  Did you read any of the links I posted?

                  You'll need to know what pin you're connecting to. You'll need to follow the directions to unbind that heater pin to make it available as a servo pin. And you'll need to format your deploy and retract commands to use the right pin you've chosen.

                        Well if you are using heater three then you need a command M307 H3 A-1 C-1 D-1 to enable use of PWM on pin 8 of the expansion connector - assuming you are correct that pin 8 is heater 3.

                        And in your M280 commands you also specify heater 3 use M288 P3 ### where ### is the servo position value needed by the BLTouch.

                        For example M280 P3 160 will clear a BLTouch alarm condition.

                        I put all the needed commands for configuring a Z-probe using a BLTouch in a file named configprobe.g. Then I call this file where needed.

                        This is what is in that file - I am using heater 7:

                        M307 H7 A-1 C-1 D-1 ; disable heater 7 to enable PWM5 - PWM signal still appears on E6 connector on Duex5
                        M558 P9 H5 F300 T6000 A5 S0.01 R0.2 ; set probe configuration - step 1
                        G31 X-44 Y0 Z1.350 P25 ; set probe configuration - step 2
                        M280 P7 S160 ; clear BLTouch alarm (if any)

                        Frederick

                        Printers: A FT-5 with the 713 upgrade bits, a custom MarkForged style, a small Utilmaker style, a small CoreXY from kit and a E3D MS/TC setup. Various hotends. Using Duets (2 and 3) running 3.4.6

                            side note B4138 is the default and is most likely wrong for your thermistors.
