MAXTEMP triggered error

Recommended Posts

Posted · MAXTEMP triggered error


I keep getting the following error while printing:


: Extruder switched off. MAXTEMP triggered !

Error:Printer stopped deu to errors. Fix the error and use M999 to restart!. (Temperature is reset. Set it before restarting)

I'm running Ultimaker on Marlin firmware controlled from PrintRun.

After this error is shown, I cannot issue any commands to Ultimaker anymore and need to reset it. Then it works for a while until the error shows up again.

Anybody has seen as well? Googling the error didn't produce much...

    It indicates you have a problem with the temperature sensor. Double check if the yellow and red wire on top of the head are screwed in tightly, and the 3 point cable connection is firmly attached.

    Thanks for the input and quick replies. I had the time to test it out in the meantime.

    The cables were connected correctly, but I still unplugged the three wire plug and plugged it back in. I suspect that it may have gotten some unwanted tension as I don't run the cables in parallel with Bowden tube since I had a plug. I have changed this now.

    The other thing I noticed was the that heat shield around the thermocouple was touching the back of the heating element. I separated them and since then it has been printing fine. Don't know if this is indeed heat transfer to the thermocouple via the braided heat shield or maybe EMI.
