Spontaneous cable failure can be bear to track down. A video cable flaw that prevents a linux PC from booting must be so serious that it prevents the PC from detecting it is connected. The terminal screen is minimal text output that the system seems to default to when no video device is found. Plug&Play failure.
Very glad to read you've got it working again. Out of three Probotix CNCs and 2 CNC Sharks I oversee none have lived a life with no problems that eventually popped up. Blown fuses on the Sharks, probably from power surges. Battery inside the PCs that eventually needs replacing. Two complete controller failures, a limit switch miswiring adventure, limit switch bouncing and failing, game controller missing (not detected), etc., seem to be the minimum one can expect.
Yet most days all 5 CNCs boot up reliably and do the work they are designed to do.
