Spurious heater fault during heating chamber
I have faced heater faults when I turn chamber heater on and leave E0&E1 to 0C for eg. to dry filaments etc.
During the chamber heating E0 & E1 rises also, even not heated by their own heaters and at some point they will report error. I have M570 set to 15C.
By looking the pinned spurious heater fault topic there is a mention that heater monitoring is activated >45C.
Basic options would be:
- Also put heater on for E0&E1 to same as chamber temp
- Widen M570 excursion limit so temps in E0&E1 does not exceed the limit.
Is that 45C / temp monitoring limit hard coded? can it be changed?
Do you have ideas how to avoid this without need to but heaters on or modify M570 limits?
Why not set the extruders temperatures equal to the target chamber temperature, or a little higher?
@dc42 Yes that is what I´ve been doing so far. Just asking if there is a possibility to set that monitoring temp to eg. 100C or something else that I could avoid this completely. I know that´s not a big deal to set those manually, but..
The temperature at which monitoring starts is hard coded, so you would need to build the firmware yourself to change it.
@dc42 Thanks for quick and prompt reply. I´ll move on with the old style
