Maxtemp error on Ulticontroller/Cura

Recommended Posts

Posted · Maxtemp error on Ulticontroller/Cura

I had just finished a print and I've recently been seeing Err:MAXTEMP show up on the ulticontroller. At one point the temperature on Ulticontroller read 386 degrees it then suddenly dropped back down. When viewing the Machine log in Cura, I found this:

Changing monitoring state from 'Offline' to 'Detecting serial port'

Recv: : Extruder switched off. MAXTEMP triggered !

Changing monitoring state from 'Operational' to 'Error: 0: Extruder switched...'

Recv: Error:Printer stopped due to errors. Fix the error and use M999 to restart. (Temperature is reset. Set it after restarting)

This seems to happen after the print is complete and before I start a new print. Not sure what this means and was hoping someone could lend some input. Thanks!

I tried to re-prepare the print in Cura, then selected print. It preheated, then I received the MaxTemp error again and it will not let me print.

I receive Machine state:Error: 0: Extruder switched

Just tightened the red/yellow wires for the temp sensor and it seems to have gone away- the red screw was a bit loose. I restarted the ultimaker as well.

Yes... you were getting a temperature reading of 386 because of the loose wires, which is beyond the safety limits built into the Marlin firmware, so it shut down the heater. Now that you've tightened things up it should be good to go again.
