      I've been running a Duet Wifi in my custom CoreXY for going on 7 years now. Love it and that's why I've decided to drop one in my CR-10S S4. Having major issues trying to get it to home. I'm using the original 2 wire endstops and have them wired to the outer pins. They show the proper states when sending M119. I'll cut to the chase and show all my info in hopes someone will tell me what I'm doing wrong. RRF 3.4.5 and latest DWC. X endstop is low end. Y endstop is high end. BLTouch for Z..................;

        @GBusy24 said in Homing issues setting up CR-10S S4:

        Y endstop is high end.

        Are you sure about that? If the endstop is at the rear for the bed, the nozzle is actually at the front and low end when homed.

        Y- should move the nozzle to the front of the bed, Y+ to the back.

          @Phaedrux Thanks. I will change Y endstop to low-end then and see what I get

            @Phaedrux, I've changed the Y homing to low end, but now my endstops show triggered when they're not. I've researched and really haven't found an answer. As stated I have the 2 wire endstops. should I flip the wires on the pins?

              Show me your current config.

              To change the trigger state you either add or remove a ! to the pin name for the endstop. So unless you changed that in the config I suspect a wiring issue?

              Did you physically move the endstop, or change the config?

                @Phaedrux, that's what I was looking for. The reference to the '!'. I had forgotten about it. Thank you kindly.
