        I'll just add that it appears you're using the wrong connectors for the board, could be creating some connection issues.

            I am now having issues trying to get the BLTouch functioning.
            When I start the system up the probe kicks out twice and the LED stays on.

              @darylprice That's normal for a BLTouch. It's in error state if it starts blinking.

                  I see what you are saying. Is there any test codes I can use so it does not jamb into my base plate. Currently if I try a G30 it just says it is already triggered

                      @darylprice You can send M401 and check if the pin drops out, it should be pulled back in when you send M402. Once you push the pin in, the Z probe reading should go to 1000, if it doesn't, you probably have a wrong input port selected or a wiring issue.

                          @darylprice Also your servo pin is inverted (see the ! before the port name in M950 S0 C"!io4.out" ; create servo #0 for BLtouch). That shouldn't be there.

                            Yes I have, I am trying to understand it all. I am using an original BLTouch version 3.1.

                                I found that the P value in the M280 P? S10 command does not want the P9 (for a BLTouch probe), but a P0. It works now with that. I found that on the BLTouch web site

                                  @darylprice the correct P value to use in the M280 command is the value you used for S in the M950 command to assign the servo pin.

                                      Quick question. What is the safest way to shutdown my printer before I cut the power?
