G Weike LC1390 machine setup in lightburn

Software that came with the machine was laser cut 5.1.
I have latest release of LB (0.9) and find my laser shows empty window. Nothing to select except go back… When i tried to add machine manually Ruida was not responding at all. I tried Trocen and in the laser window (in LB) it changed to ready. but even it is not connected now, LB still says ready.

USB i try to use is going to the 6515 board. I took some pictures as i am no longer in my workshop.
