Congratulations and welcome, glad you found Lightburn and this forum.
We need a bit more info.
What machine do you have?
Did you setup your laser as plain GRBL?
Meanwhile maybe this helps:
I have a diode machine, that is all i know. Yes it is set on GRBL
Brand and model of your machine.
Also post a screenshot of Lightburn > Edit > Device settings.
