      link text

      This the first effort to home X and Y.

      OK X is behaving very strangely.

      But as to Y:

      Is the Y endstop at the front of the machine or the back?

        @mac I see that the Duet Mini 5+ does not have on-PCB pullups on the IO pins.

        You need to go to the RRF configurator and select "Active low with pullup" if you are using normally-open switches connected to ground as endstops.

        Without a pullup, every time a stepper motor starts moving, your machine will start to get signals indicating the endstop switch is being pressed.

          @fcwilt it’s at the back.

            @alankilian sorry to disappear, texting on this iPhone 8’s a bitch. I’ll make that change and post a video of the results do you can see the results.

              So you have a moving bed.

              To get to the max end of Y the bed moves toward the front?

              To get to the min end of Y the bed moves toward the back?

              But stepping Y by minus 10 caused it to move toward the front?

                    @fcwilt yes, that is what’s happening. The bed did touch the endstop and then back off; that’s an improvement.

                      Here's the problem.

                      When you tried jogging Y by -10 it went toward the front? Correct?

                      But the homing moves were supposed to be:

                      • a minus move
                      • a plus move
                      • a minus move

                      Based on the jogging test it should have moved:

                      • toward the front
                      • toward the back
                      • toward the front

                      I think there are two problems:

                      • the normal/reverse setting for the Y stepper is wrong (see M569 P0...)
                      • the steps per mm are wrong - too few (see M92)

                      I would like you to:

                      • change the M569 setting from whatever it is to the other setting
                      • try the home Y test and observe the movements
                      • try the jogging test and verify the correct directions
                      • if the directions are correct find some means to measure a move of, say, 100mm and see if a 100mm jog moves that distance.

                      Thanks.

                        Since it's a bed-slinger in Y, isn't a PLUS move going to move the bed towards the FRONT? (Move the head towards the +y part of the bed.)

                        I may be confused.

                          Correct (about the move, not about being confused). 😉

                          But according to mac a minus jogging move was moving the beds towards the front. I can only go by what he posts.

                            @fcwilt Y homes like it should. None of the + moves work. When I -10 it moves FORWARDS.

                                @mac said in I could use some help:

                                @fcwilt Y homes like it should. None of the + moves work. When I -10 it moves FORWARDS.

                                I understand about the jogging move.

                                And since it is wrong you need to change normal to reverse or vice-versa in the M569 for the Y stepper.

                                That should get jogging going in the right direction.

                                IF it does try homing Y
