Why does this error occur and what do I do the next time it appears?
Is there a Macro I can use to solve the problem?

ERROR END
When my NEJE MAX 3 is running a job and I press “STOP” because I need to stop my laser, the error is displayed.
Subsequently, when I restart the job, the coordinates no longer match.
Info : When I press “STOP” the laser moves to the “HOME” position
How do I solve the problem so that my NEJE 3 MAX can be started again after “STOP” and complete the task?
The “STOP” button issues a Machine Reset to ensure the laser is turned off. This is likely the reason the laser moves to the “HOME” position. The data in the buffer would be dumped when the Machine is reset.
Please test the functionality of the “Pause” button to see if it will work for you. I don’t know if the “Pause” button behavior is immediate or if the Pause command will be Queued along with the commands to the engraver. It ‘should’ be immediate but I can’t say with any certainty.
It would be best to ask NEJE which of the Feed Hold, Cycle Start behaviors they use in their similar code between lines 163 and 200 of the following code are permitted by them. I hope they have a Firmware behavior that can be called and give you the results you are looking for. The Dev team has confirmed that custom Ctrl characters are not available to be sent by LightBurn.
