      Hi, I am new, have tried to fix endstops for my 3d with duet2wifi RepRapFirmware for Duet 2, 2.02 (RTOS) (2018-12-24b1) has built itself a BLV_mgn12. The problem is that can not understand how would microswitch work, have contacted switch to the outermost contacts on the switch NC and on duet2wifi on signal and ground, but without results. can any of you help me with that.
      Regards Christian

        did you have this switch?
        endstop microswitch
        if yes on the thirt picture you see the cabel red is +3.3V black is gnd(-) and green is signal.

            NC normaly means not conneted you have to use NO & C

              Have followed this, do you know rotation on x y z stepper motor, maybe also my problem with switch.

                on a switch NC is normally normally closed, and its preferred for limit switches as it would prevent movement if the wire breaks.

                  maybe post a picture of switch and duet connection?

                    some pictures , where it appears that the endstop LED is on, but Z Y X is not in the home position, if I press each switch, the endstop LED is off on duet2wifi.
                    Should it be so?
                    home position OFF, not home location ON!

                                I suggest you start by testing the endstop switch and wiring. See https://duet3d.dozuki.com/Wiki/Connecting_endstop_switches#Section_Test_endstop_switches.

                                  Have fixed now, by changing the switch to NO and working now.
                                  Thanks for the help.

                                  But one more question, how can change the speed of Z axis on the way to endstop (low switch) to a slow speed last cm to endstop. The same speed, as on the x and y axis. I have this config.g

                                    how can change the speed of Z axis on the way to endstop (low switch) to a slow speed last cm to endstop.

                                    It's not possible to slow down before the endstop, because it doesn't know where the endstop is before being homed. Typically homing would be done in two passes. A fast movement to the endstop, followed by a short movement back, and then a slower movement towards the endstop again for better accuracy.
