I’ve seen this in the forum before , but I can never find the “fix.” I’m running cheap 50watt with the TL-A1 controller. It has been fine for several months but my computer took a dive, Installed everything but no communication with Lightburn. I am certain its not a Lightburn problem, but I thought I saw it resolved here. I have installed every driver I can think of, Find My Device can’t find it. Manual install acts like its working but no connection (defaults to Auto, no com port). For what it’s worth I can connect through the Auto Laser Program that came with the machine, but that’s via WiFi.
