Totally new to LightBurn, just got a Boss LS1420. Using MacBook Pro, High Sierra 10.13.6. LightBurn will not detect the laser via usb cable. I have also tried adding it manually, still shows as disconnected. I get a failed to send notice followed by a machine must be paused or buy notice when I tried sending a file to the laser. I do not have ability to connect via ethernet.
The simplest approach is going to be getting an Ethernet adapter for the Mac and connecting that way. There is a well documented conflict between the USB / Serial driver included in MacOS and the FTDI driver used by the USB chip in the Ruida controller.
Are you able to ping the laser from the command line? If the IP address in the software and the laser match, make sure that you can ping that IP from the terminal window. I assume you have run the cable from the Ethernet adapter to the port on the laser?
Discovered can connect with usb by starting the laser and connecting to the computer before turning on the computer. I had restarted the computer before both before and after connecting the laser however I do not know for sure that I had the laser turned on before restarting the computer. In the end it was as expected, operator error on my part.
That’s odd - it shouldn’t be necessary to power the laser before powering up the computer. If you run LightBurn first, then plug in the laser, you can right-click the ‘Devices’ button to have LightBurn re-scan for the laser.
