This is a message from the board saying it was locked, and LightBurn unlocked it. What is the problem?
i was unable to start burn and do anything , sorry im noob in this. and the laser did’t fire at all . try to move the laser head to the point but it back to home once i hit “start”
Change this back to the default setting, “Absolute Coordinates”:
