    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.

      and simulated the proj

      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

            What I'll do now I know this file runs is to let it finish, s
            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.

                  Thank you, @joergs5

                  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 👍

                      Maybe I've got to the bottom of this...

                      I've simulated several files from a specific Work XYZ, which is X27 Y198 and Z82. The maximum axis limits are X535 Y787 Z100.

                      I need to look at the Vectric software to see why, but I've compared a few gcode files produced by the Vectric software, and I've found this:

                      In both working and non-working files, there are four consistent lines of code at the start (excluding the headers) as follows:

                      G17 (Sets the XY plane for arc moves)
                      G21 (Sets the units to mm)
                      G90 (Sets to absolute positioning)

                      Then the files differ.

                      In the files that can be simulated, this is the next line:

                      G0Z6.350 (Which moves the Z axes to a safe height, I guess)

                      ...but in the files that can't be simulated, this is the next line:

                      G0Z20.320

                      I think this is the problem because if the Z Axis is already at 82mm when the Work XYZ is set, then trying to move the Z axis another 20.320mm will exceed the available Z axis movement of 100mm (82 + 20.32 = 102.32mm).

                      Does anyone agree, or am I talking out of my hat?

                      Thanks

                        Yes, I think that is exactly what is happening.

                          Thank you, @dc42.

                          I was getting a bit tied up with this last night, but in the cold light of day - and after a good nights sleep! - a clear look at the problem certainly helps.

                          My thanks to @JoergS5 for pointing me towards the Z height, and everyone else who joined me on this journey.

                          Now all I have to do is find out why and prevent it from ruining my day again! 👏 👏
