Maxtemp error on Ulticontroller/Cura

Recommended Posts

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!

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
