    Function testing hot bed.

    Just a quick question. Is there any good solid way of testing the hot bed other than doing an ohm's test to see if the bed is bad or if it is the main board that is having the problem?

    Check voltage going into bed. If voltage is there and bed doesn't get hot = bad bed

      I suppose that would work. Couldnt find my multi-meter so what I ended up doing was hooking the hot bed up to the extruder output and then swapped the hotbed and exturder thermocoulples then ran a preheat cycle for a minute to see if the bed got warm. Looks like my mainboard is faulty It isn't warming normally.
