Help needed on TL 3120 with Light burn

Hi

I have just acquired a 100W TL3120 700 x 500 and I am struggling to get it to work with Light burn. The Firmware version is 1.17.8.16 - There is a USB connection from my MAC that is running light burn. I have tried trodden (ethernet only connection) and ruins via usb.

When I purchased my ruida 600x900 it was pretty much plug and play.

Any help very much appreciated!

I have no idea what “trodden” and “ruins” are. Which version of LightBurn do you have?
