When adding a Galvo to LightBurn, it can only choose the correct device type for you. The controller does not hold any preferences, like with GRBL firmware.
You need to load the manufacturer’s config file during the setup. Please see:
I can’t say for sure.
We were asked about the “Unrecognized board signature” message here and here, but I haven’t heard back.
EZCAD reported that the controller is an USB-LITE board, so it should work in LightBurn!
Load your manufacturer’s markcfg7 file as explained in the link above and let us know how it works please
