Hola, tengo problemas con el uso del programa. Cuando estoy realizando cortes, la máquina se detiene y el tiempo sigue contando. La unica opción que me queda es detener el corte e intentarlo de nuevo. A veces detiene el trabajo y otras veces no responde y o sigue quemando el laser o se apaga pero el programa sigue como si estuviera trabajando con el tiempo corriendo y no responde
Screen shots would help. Setup and device settings. I had a similar problem and it turned out it was the port expander i was using to connect the machine to my computer. Removed it and that corrected the issue. Try moving cable to another USB port or switching cables. Is baud rate set correctly
Hi. I’ve tried everything related to USB, and even the baud rate is at the recommended 115200. I can’t solve the problem. 
Try downloading a copy of LaserGRBL. And see if it works with that. That will till you if its your machine or something with the Lightburn. I’m sure baud rate should be 115200. You don’t say what machine you have.
