Connect laser to Lightburn

[Flegge (Floriano Flegar)]

Total newbee to Lightburn trying to connect.
My setup:
Ender 3, SKR e3 mini V1.2 mainboard, Marlin 2.0.9.x OS, Sovol 5w Laser diod

The console just “Waiting för connection…”
Anyone that could point me in the right direction to solve this, would be most appreciated.
