Remove the "temperature not rising fast enough" errors??
-
Is there a way to complete remove the "temperature not rising fast enough errors? I just want to use bang bang mode without worrying about my heater faulting. IT IS GETTING EXTREMELY ANNOYING!!! I had bang bang mode enabled and removed my heater from the config.override but I am still getting "temperature not rising fast enough" errors and it is ruining everything....How do I just remove this heater fault completely???

Just PID tune the bed.

I'm not using it on a bed heater I'm using the temperature control for a heated fan for a side project. PID doesn't work or randomly fails.

Try changing the time outs on heater faults.
Just try to remember that the heater watchdog is just trying to look out for you. If a heater isn't heating it could mean the thermistor has become detached from the heater.
What firmware version are you running? The PID tuning algorithm was updated in 3.2 and has better behaviour with slow heaters like this, so might be worth a try if you haven't. You can also manually tune the PID values.

@injoi9000, I suggest you run manual tuning as described at https://duet3d.dozuki.com/Wiki/Tuning_the_heater_temperature_control#Section_Setting_the_model_parameters_manually to construct a M307 command more appropriate to that heater than the default one. RRF uses the M307 parameters to determine the expected heating rate.

Why is it that when my heater is in bang bang mode it still sends a temperature not rising fast enough error? It is super annoying...I can't disable it with the m570 command either I am still getting errors...
How do I delete "temperature not rising fast enough"?

Because the heater protection needs to know the characteristics of the heater to be able to detect a disconnected thermistor, regardless of the control mode. See my previous response.
