Think you got me on the right track. Using Lightburn with the 2 diode lasers I have requires me to have my computer connected via usb to the controllers and ties up my computer while running those lasers. Lasercad saves files in UD5 so I could put them on a usb stick and insert the stick into the Trocen and pull from there or I can send the files over ethernet direct to the machine from my PC. If the DSP version of Lightburn has ethernet port for trocen and can save files as UD5 then I should have the same abilities as I do now with Lasercad.
