    Had a thermal runaway error yesterday, check cabling etc, and all looks good, but now the bed wont head up, i have checked the bed connections, and seeing the heater element from the RUMBA end (1.8 Ω) and bed thermister (210K @ 10°), when i turn up the temp on the RUMBA (running RC6 for hybrid pro) even the HB led does not light up.

    So do you think a Firmware reload might fix it or is the RUMBA dead.

    Do you get power coming out the HB output when you turn it on?

    Are you getting voltage into the HB input on the Rumba?

    ok, I expect the rumba is faulty. You can try flashing the firmware but I doubt it will do anything.

    @Greg, I have tried that, but still the same. I presume the RUMBA is covered under warranty ? I ask as i will be coming down to you in a few hours to pick up a load of PLA filament, so could pick up a replacement RUMBA at the same time.
