    I got a new ramps board due to have it burned up. I swapped it out for a new one. Now my bed doesn't want to hear up plus I think I burned up my fan for my ramps

    I have the R1 and using Windows

    I tried to look for a wiring diagram for the boards and no luck.

    Any help
    Thanks

    What temp does your bed show without heating up ? Polarity matters with the fans. Reverse the polarity and see if it will work.

    Glad you got her working. Are you certain the bed connections are tight? If its showing 28 you can assume the thermistor is good. So if the connections are good most likely cause is q3 mosfet failed. Share some photos of your wiring ?

    Ok, the girl is heating up which is weird for me. When adjusted the fan wiring and I just did a test of the bed for shits and giggles, it started heating up.
    So I think you were right. The wire most not been tight

    ** now a new problem. Can't get the extruder to work

    Can you be a wee bit more specific? :)
    By 'not working' do you mean it won't heat up or once hot, it won't extrude/turn? (it won't extrude cold -- FYI)

    Are you doing this with the extruder hot? It will not try to turn if the extruder is cold.

    If you try to do it cold you will get a MINTEMP error generally.
