Connecting to the Laser
Once a laser has been added to LightBurn, it should appear in the list of devices to the right of the Devices button in the Laser Window. If you only have a single laser, it will be automatically chosen for you.
If you have more than one laser set up, you might need to select the one to connect to by clicking here:
Depending on the type of controller you have, you might have to manually choose the port that the laser is connected to, by clicking where you see Choose in the Laser Window:
As long as your laser is connected to the same communication port, LightBurn will reconnect when you re-start. If you reboot your computer, or plug the controller into a different USB port, you might need to re-select it.
If you see the (Choose) as shown above, you need to select the port. If no ports are listed in the drop-down, it means that no devices were found, which could mean that it is not plugged in correctly, isn't powered, or you're missing a driver.
If your laser disconnects for some reason, or enters an alarm state and needs to be reset, you can quickly re-connect by right-clicking the Devices button in the Laser Window.
