SD card works but the laser is not recognised via Lightburn. Neither on Mac nor on Windows. Various cables have also been tested. Is there another tip here?
This works well for me (Win11 / LightBurn 1.7.04). You can select the devices in the Laser window. Under Search lasers you will see a list of connected lasers, select them and confirm with OK. The Falcon has the name GRBL-M3 1.1e.
