I have a generic 50W Fiber Laser with an apparently generic JCZ board. I can load EZCAD2 on my Windows PC and start the laser, then move the USB cable to my Macbook Air with Lightburn and it will work.
But Lightburn can not find or use the laser on its own. I have version 1.2.04 installed. I believe there is some part of the protocol that is not identical when LB scans for devices. Is there a diagnostic log I can see of the scan process?
