Heater error when tuning.

mjimeyg

I am trying to run M303 H1 S275 on my E3D Cyclops but when it gets to phase 2 an error occurs:

Error: Heater 0 fault: monitor 0 was triggered

The full out put from issuing the command is:

Error: Heater 0 fault: monitor 0 was triggered

Auto tune starting phase 2, settling

Auto tune starting phase 1, heating up

M303 H1 S275;
Auto tuning heater 1 using target temperature 275.0°C and PWM 1.00 - do not leave printer unattended

The hotend reaches the target temperature but then it simply fails. I also don't understand why it is reporting an error on Heater 0 as I am testing Heater 1.

Is there a place I can see error message definitions? What is monitor 0?

Below is my config.g:

@mjimeyg the error message indicates that the over temperature limit was triggered. Either choose a lower temperature in the M303 tuning command, or use the M143 command to temporarily increase the over temperature limit.

What filament do you print with? 275C is higher than most filaments need.

@dc42 Lowering the target temperature fixed it.

I use PLA and PETG, occassionally ASA. I thought tuning required the maximum temperature the hotend could reach.
