      @joergs5 ok, I think it's 218800/547 = 400.

      This means, for every mm your router moves, the Count value for X will be incremented by 400. So you can always see where the firmware thinks that your router is.

      Now before you start the error G0/G1 move, you can make a M114 and know where the router is. (of course the G1 before will be this position also in most cases, but to be sure...).

      NB the values being all 0 at the beginning is, because firmware doesn't know where your steppers are at the beginning. This is what homing is meant for: telling the firmware where the stepper's positions are. The only reason why the firmware Count values and true stepper position may vary is if there are lost steps (M122 hiccups hight numbers will tell you).

        X:547.000 Y:784.000 Z:97.000 E:0.000 Count 218800 313600 38800

        547 * 400 = 218800
        784 * 400 = 313600
        97 * 400 = 38800

        or other round, from the Count value divide by your M92 (400) and you'll get the current mm position.

          Should I move the axes to the Work XYZ first, set Work XYZ, then run M114?

            My proposal would be to move to the last position which is ok. Then make a M114 and notify the Count values, then verify that the next command throws an error.

              @joergs5 Sorry, I edited the question as you answered...

              I've now placed the spindle at the Work XYZ (without the cutter installed!) so should I set Work XYZ then run M114?

                  Interesting! I was not sure, whether it will be corrected or not.

                  So work change (did you make it by G54?) doesn't change the count values.

                  I've learned here something also!
                  XYZ are the values from the work XYZ view, and the Machine coordinates behind are the true original coordinates.

                    I just clicked the Work XYZ button on the Dashboard. I don't know anything about G54??

                      The workzero.g file has the following lines:

                      ; workzero.g

                      ; G90 ; set to absolute positioning
                      G53 G1 Z{move.axes[2].max} F1500 ; raise the Z to the highest position
                      G1 X0 Y0 F2400 ; go directly above the work zero position
                      G1 Z0 F2400 ; go to the work Z zero position

                        I think it's not so important now, we want to find the reason for the error message.
                        One possible reason could be that the M208 limits take the XYZ values. But let's verify by you searching for the first error G0/G1.

                          @joergs5 OK. Shall I load and run the file?

                          Actually, what I did was upload the gcode file, then right-clicked it and simulated the project, with these results:

                          21/05/2022, 19:54:21 File 0:/gcodes/102 Avalon Pocket_1-102 Avalon Pocket.gcode will print in 0h 14m plus heating time

                            G53

                            G53 is to clear coordinate changes and not using any machine coordinates, so I would not run it.
                            https://duet3d.dozuki.com/Wiki/Gcode#Section_G53_Use_machine_coordinates

                            There should be G54 to G59 somewhere else, probably in your Cut2D software.

                            The problem now is that I don't know your software and which commands are run. I can only help to find out the reason why there is the G0/G1 error message.

                              unfortunately it didn't find an error line, so it didn't help.
                              The simulation mode may have some shortcuts, e.g. not checking limits....

                                Well, starting the file seemed to work, too.

                                I'm not sure what's going on here, but I'm also getting random disconnects

                                    hut everything down and use the same Work XYZ coordinates again tomorrow, but with the other file, and see how that goes.

                                        @nightowl999 when you get a G0/G1 error, you know now how to analyze it. I expect a conflict between what the software wants to make and your M208 limits.

                                        I checked Cut2D, there was one similar problem in
                                        https://forum.vectric.com/viewtopic.php?t=32804
                                        but I am not sure whether it can be the reason in your case.

                                          I'll check that forum out tomorrow, but that thread is exactly the issue here - if not the resolution!

                                          Have a good evening and thank you for your help 👍
