            that script is set up to use a probe to homez not the endstop at max.

                you can either have a probe or an endstop, not both.

                see
                https://duet3d.dozuki.com/Wiki/Gcode#Section_M574_Set_endstop_configuration

                Snnn Endstop type: 0 = active low endstop input, 1 = active high endstop input, 2 = Z probe, 3 = motor load detection

                          @olivier Rather than using a switch, if you just want to lower the bed then send it to that specific position at the end of the print: G1 Zzzz Fnnnn

                          You don't need a switch because the printer knows where Z is at the end of the print.

                            Hi @T3P3Tony ,
                            Yes but I would like to add a user macro "down the bed" without homing (for exemple after a power failure).

                            Maybe it's possible with stall detection ?

                              @olivier It may be possible with stall detection. but if you just want a macro and you have a switch then just write the macro to move and stop when the switch is sensed, wrap the movement in a line to configure that switch as the Z endstop and then configure it back to the probe after the movement has finished.

                                Could you just write this 2 or 3 lines ? Thank you for your help.

                                  @olivier If you determine the Z axis setting to use a switch at Z max (i think you have already done that) then the macro would be something like:

                                  Z_Max_home.g macro in /macros/

                                  M574 Z2 S0
                                  G1 Z300 F<something sensible> H1
                                  M574 <whatever you have in your config.g to setup for the BL touch>

                                  Note i have not tried this so you will need to experiment a bit and have your hand on the power button as things move!

                                    Bed going down but don't stop when I press the switch. The endstop LED react correctly
