So… tried laser for the first time, run through automatic setup on small screen, no focus possible, did update then it calibrated successfully, but then I turned on Luban and it was not possible to get background. I checked on small screen and camera is yellow while laser and enclosure are green. I tried to calibrate camera on small screen and it says camera is not connected. Advice how to proceed. ---

likely you are connected via USB ? Camera only implemented via WIFI… ---

No. No cables. Only wifi.
