My Lulzbot Mini has been printing fine and suddenly started aborting about 20 minutes into a print. The Cura error log looks like this:
Recv: ok

Recv: Error:Temperature heated bed switched off. MAXTEMP triggered !!
Changing monitoring state from ‘Printing’ to ‘Error: Temperature heated bed switched off…’
Recv: Error:Printer stopped due to errors. Fix the error and use M999 to restart. (Temperature is reset. Set it after restarting)
Recv: Printer stopped due to errors. Fix the error and use M999 to restart. (Temperature is reset. Set it after restarting)
Recv: ok
Recv: ok
Recv: ok
Even though it says the MAXTEMP is reached, there is no spike on the temperature graph for either the head or the bed.
I tried running the printer on a hot day and a cold day and same error. Other posts with this problem seem to have different circumstances – mostly that the printer doesn’t print at all. If I keep the print times under 20 minutes, I can manage multiple prints.
Suggestions on how I can fix this?
