A heater fault occurs on the LC1 board.
-
A heater fault occurs on the LC1 board at a frequency of about 70%.
Environment
- firmware version: 3.2
- temperature sensor: PT1000
- heating block: Volcano
Symptom
When the temperature is set, the set temperature is normally reached.
After 10~20 seconds, the heater turns off due to a fault.
There is no error message in the console.

@psyblue said in A heater fault occurs on the LC1 board.:
M308 S0 P"temp0" Y"thermistor" ; T100000 B4138 ; configure sensor 0 as thermistor on pin bedtemp
this is missing a T and B value
Bootloader ID: not available
you need to update the bootloader for the bltouch to work correctly at startup.
G31 P500 X0 Y0 Z-0.3 ; Liquid Head
this is missing x and y offset
M307 H1 A1077.7 C574.8 D5.6 S1.00 V23.9 B0 ; Auto tune result - Super volcano
this is the old pid tuning that does not take into account the fan. that could cause problems when the fan turns on

Thank you for your interest in my writing.
I have a few questions in your relpy.
How to update the bootloader? Is it different from the firmware update?
How did you know it was old PID tunning just by looking at the result? Fortunately, I don't use a fan.
Thanks again. -

@Veti
Great thanks!!!I'll update the boot-loader & tuning values.
-
The cause was old auto tuning value.
I commented the M307 line and using the default value, the fault situation disappeared.Thanks Veti !!
-
there is a beta of 3.3 that allows you to do tuning on the toolboard
