      Can you confirm that when you hit home all the X and Y axis start moving towards the endstops and actually hit them?

      You can remove the second Z lift as well. It's already lifted once at the start of the file, so no need to raise it again. This one before the G90. Though it shouldn't be causing the problem.

      G1 S2 Z5 F6000 ;lift Z relative to current position
      G90 ;absolute positioning

        Try again stepping through the file one line at a time by copying and pasting each line exactly as you you have it in the homeall file, into the console. But before you do that, cycle the power so that you start with all axes un - homed. If you look at the "Machine Control" tab, you start with all the axes highlighted in yellow. So switch to the console, enter the first commend, then switch back to the Machine Control tab. Then repeat for the next command in your homeall file. Every time an axis homes successfully, (i.e. an endstop triggers when the move has an S1 command) each one will change from yellow to blue. At the end of the sequence, they should all be blue. If not, where did it go tits up?

          @phaedrux yes, they physically hit the end stops, at which time they clear the "not homed" status.

          X, Y, and Z

            Yes when X and Y hit the endstops they should be marked as homed, that is correct. Are you saying they also mark the Z axis as homed?

            Can you post your config.g file so we can see what your endstops are configured as?

              it looks like the very first G1 Z5 F6000 S2 is the culprit

                  should the Y axis be negative here as well? Or is the end stop establishing "Hard Zero"?

                    OK, didn't I read that Z cannot make a move without Homing the other exes first? I had the comment to allow moves before homing, but I was told to remove that. S2 denotes a move ignoring limits though, correct?

                      Why do you think that? What happens? What should happen is that the bed moves 5mm away from the nozzle and nothing else. You shouldn't get an error message. The homing state won't change because of the S2 parameter. If you do get an error message at this point, try deleting that line and re-typing it, just in case there is a hidden character or some such that is screwing things up.

                      You can move Z if you include the S2 parameter. S2 ignores end stop detection.

                      M574 X1 Y0 S1 ; Set active low and disabled endstops

                      This looks odd.

                        M208 X-8:300 Y0:300 ;Set Axis Limits

                        That would indicate that your X axis is potentially longer than just 300mm. It's 308 actually. so in the rare case that your X axis is all the way to the max end, it won't be able to reach the endstop switch if your homing file only tells it to move 300mm. So your X axis homing move would need to be more than 300.

                        So your first X and Y moves should be:

                        G1 S1 X-400 Y-400 F10000 ;move quickly to X or Y endstop and stop there (first pass)
                        G1 S1 X-400 F10000 ;Now do a fast move just on X and detect end stop
                        G1 S1 Y-400 F10000 ;Likewise Y
                        

                        S2 denotes a move ignoring limits though, correct?

                        The G1 S2 switch will allow that move even if the axis isn't homed. So for the Z axis, it is raising it out of the way a short amount to prevent any collisions.

                        ; Endstops
                        M574 X1 Y0 S1 ; Set active low and disabled endstops

                        This is incorrect. Y0 indicates there is no endstop for Y.

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

                        If the X and Y endstops are on the low end, it should be M574 X1 Y1 Z0 S1

                          Ok, I had to take a break... I was too frustrated...

                          If I manually type in the individual lines of G code... Not copy and paste, physically type them in, I can get the entire code in without an error...

                          So I re-typed the entire Homeall.G from scratch, and it errors... Error: G30 Insufficient axes homed for bed probing....... @dc42, any ideas? This is weeks I've been fighting the same problem. I know everyone has picked my homeall apart, but nothing I've changed seemed to have an effect on the actual problem I'm having.

                                Does homex honey and homez work independently?

                                  Just the Homeall is hosed..

                                    If I simply take each of the x, Y, and Z files, and paste them into a Homeall, could you tell me what stuff to remove if it tests ok?

                                      Ok, I made a fresh .txt file, and re-named it so the file extension was .g I simply pasted the 3 scripts that do successfully run when run individually, and put them into one file so they should run in the exact same manner as If I manually pushed the Home x home Y and Home Z buttons, and it still gives the G30 error... it doesn't seem to care what is in the file, it's going to error.

                                        @steve-lynch I think this is driving all of us crazy - not just you ☺

                                        Can you post you entire config.g file - not just extracts. Can you also post your config-override.g if you use one.

                                        Oh and let us know what firmware version and whether this is an Ethernet/WiFi board or a Maestro.

                                            @steve-lynch Nothing drastic there that leaps out at me except you have some strange parameters in your G31 that I'm not familiar with, and they aren't documented in the Wiki. Specifically R0.2 and A3. Is that something to do with the BL touch? Like I said, they aren't documented here

                                            https://duet3d.dozuki.com/Wiki/Gcode#Section_G31_Set_or_Report_Current_Probe_status

                                            but I don't use a BL touch so maybe you need them? Maybe someone else will know.

                                            Just a small thing, but if you don't have config_override.g file, you might as well delete the M501 which calls it at the end of your config.g.
