Weird error message when calibrating nozzle heater....
i have try to tunning nozzle heater temperature control.
With this gcode
M303 H1 S240
and.... this error
21/2/2022 10:38:35 Error: Heater 0 fault: monitor 0 was triggered 21/2/2022 10:38:32 Auto tune starting phase 2, settling 21/2/2022 10:37:17 Auto tune starting phase 1, heating up 21/2/2022 10:37:12 M303 H1 S240 Auto tuning heater 1 using target temperature 240.0°C and PWM 1.00 - do not leave printer unattended
this bug is new. Implying?
What firmware version?
For tuning the hotend, try using M303 T0 S240 instead to try tuning as a tool instead of just a heater. This will use the fan to try and compensate for it's cooling effect.

@peirof When you ran this test did you also have the bed heater turned on?

I have tried that gcode (M303 T0 S240), and the same error. But the Hotend fan does not turn... I thought that the fan was not working... but on the Status page, I made it turn manually... I am going to check if I have the temperature sensor configured correctly, maybe it's reading another temperature than the real one...
