        could it be a faulty BL touch?

          I guess its a possibility. If the code is all correct, and i'm confident hardware is ok, then there aren't many other options.

            @Adam-V3D said in Can't get BL Touch working:

            the pin also doesnt jump back into the retracted position.

            that tells me there is a problem with your bltouch.

            after issuing the deploy probe a small push on the pin should cause the bltouch to pull up the pin.

              Looks like i'm going to have to try and get a replacement probe then. I feel like that's going to be easier said than done.

              Feeling like this might be my first and last experience with BL touch...

                        any help that people are trying to give is appreciated.
                        we are here to learn from each other.

                        he stated that

                        When I send G30 the probe deploys but pin contact doesn't trigger, the pin also doesnt jump back into the retracted position.

                        the G30 command however does not execute the bed.g file.
                        The G32 command executes the bed.g.

                              Flipped over the two pins that go to the Z probe header and now it works. Bit odd because i'm sure it was wired correctly.

                                Glad to hear it's working.

                                But clearly it wasn't wired correctly and is now 😉
