        Can you copy and paste this line into the gcode console and report back what it says?

            Did a test, pressure plate goes up, but the pin from the Bltouch doesn't go out

              And if you send M950 S0 C"exp.heater3" does M401 and M402 work?

                  Do you get an error from sending that M950?

                  If you replace the M558 line in your config with the one you manually sent, does it stop the error message you were getting before?

                      Are you sure you have the yellow wire connected to exp.heater3?

                          Can you test with a different heater pin then? exp.heater7 perhaps? Alter the M950 command accordingly.

                          It may also be worthwhile testing with a fresh set of configs from the config tool.

                            We had already tested heater 7 and will be testing heater 5 and 7 again soon.

                            I just created a new config, we will test it afterwards.

                            Also, a big thank you for your help! That's great

                              @schotte I am not sure, but
                              M558 P9 C"^zprobe.in" H12 R1.0 F500:F120 T6000
                              F parameter looks wrong to me, it should be F500:120 (so without second F letter).

                                Have tested heater 5 and 7, Bltouch still doesn't work.

                                New SD card with new system didn't help either.

                                  Can you test with the BLTouch leads connected directly to the board without any extension?

                                  The M558 problem is resolved, now we just need to get the servo communicating.

                                  You mentioned in your first post that the power on pin test of the bltouch moves slowly. Is the BLtouch held upright? Have you tried connecting only 5v and ground?

                                    We can no longer connect the Bltouch directly without further.

                                    If we unplug the yellow wire from the Heater5 pin, the Bltouch will do the self-test at normal speed. Once the yellow wire is reconnected, again slowly.

                                    @JoergS5

                                    we will test again when the BLtouch is running - thanks for the tip

                                      @schotte another thing to check is whether the probe pin can move correctly. The distance and freedom of moving is defined by the screw at the top which can be changed with an allen key.

                                        The pen is smooth, shouldn't be a problem

                                        Our measurement is 0.2mm

                                          If you're certain the wiring is correct and there is continuity on the wires there is still the possibility the probe itself is defective.

                                          Do you have another printer to test the probe with, or another probe to test on this printer?

                                            I'm helping a friend online through Teamviewer and he lives about 90 miles away. He's going to order a new one and then we'll see.

                                            We will then report, hopefully it works with the new one.
