    Nope, it does not specify... I just keep getting the same error message as I posted. I just tried a hour ago and still got the error message. I can't even have the computer move any motors as the error comes up. I'm really new to this 3d printing world and starting to really want to give up.

    I can only get the extruder temp to 25c but still with the error message the heated bed works fine.

    What does your temp graph look like?

    Ok there we go "Extruder MINTEMP triggered"

    Somethings happening where your thermistor is jumping open for a moment.

    Is there movement when this occurs? Could be a loose solder connection.

    You can do some basic trouble shooting yourself. Follow the thermistor wire from the hot end to the ramps board, giving it a pull test at each connection point. There could be as many as 4 on the wire so be sure you check the whole length. If the cable breaks when you pull on it it's a loose solder and will need repair or replacement.

    Otherwise there's an issue with the thermistor itself and needs replacing.

    Brandon23...Any updates. I just got a new hot end and new thermistor. The old hot end leaked, but never stopped or gave me errors. The new one stops at different points in the print and hasn't finished a successful print since I put it in 6 days ago.

    Seemed to have mine fixed now. Mike Kelly was pointing out the thermistor connection might be bad. I checked and my connection was good, but the way the wires are supposed to be tied below the spool feed stepper motor is not good on the connection. I cut mine loose and it finally made it through a print.
