I’ve tried to tell so many people this, but the ease of USB makes it very attractive. We’re genuinely considering removing USB as an option altogether if I can’t figure out a way to make it reliable.
I have a side project we’re working on, using a Raspberry Pi as a relay. It would plug into the laser with a network cable, and connect to your home WIFI network, and LightBurn will talk to the laser through the Pi. Simple setup, will cost about $50 (price of the Pi, power supply, SD card and cable), and throughput is 600kb/sec in testing. Not ready for release yet, but getting there.
