LightBurn se para en medio de un trabajo ( stops in the middle of a job )

Electromagnetic (radio) interference is the greatest reason for jobs stopping.
The next greatest reasons are screen savers, Sleep mode and USB suspend (Selective Suspend) of the communications ports.

"when I execute a file with small details it stops suddenly without emitting light or moving and in LightBurn the timer continues running, but not the progress bar,"

Because of this behavior, I am thinking the buffer in the controller is large, and when the buffer is full and communication pauses this creates enough quiet-time to allow the USB port to time-out.
It may be most productive to slow the communication speed so the buffer does not fill up or need to pause communication to catch up.
