I get the Error message after the heater has been turned off
19:53:43.785 : DebugLevel:14
19:53:43.797 : Error:One heater seems decoupled from thermistor - disabling all for safety!
19:53:43.798 : Error:Temp. raised to slow. Rise = -12.58 after 13079 ms
19:53:43.802 : Disabling all heaters due to detected sensor defect.
19:53:43.805 : DebugLevel:14
If I manually set the temperature it is stable and stays there for a long time
As soon as I start to print after coming up to temperature or having had the temperature stable and started to print, the heater gets turned off somehow and I get the message above about 13 seconds later according to the Temperature Curve and the time line and the log message
I have attached an image for the case where it came up to temperature but the same thing happens if it were at temperature a long time (lets say 10 minutes or more).
I also tried moving the extruder with the manual controls while it was at temperature and did not see this problem.
I know the detection code is not causing the problem, only detecting it after the case.
I would appreciate any suggestions.
Thanks
