@oliof I wanted to ask you but there is an algorithmic auto for temperatures because I don't like the one I have at all I would like that there would be an algorithmic auto that, based on the temperature that rises and falls, the rule automatically

I don't fully understand your request. Is this still about the fan to cool the stepper, or some other issue?

I do not speak the regulation of the nozzle temperature I now have an algorithm that I created that is stable but when I suddenly increase the speed the temperature drops by 2 degrees even by degrees

@oliof temperature excursion exceeded 15.0°C this parameter can be changed instead of 15 degrees to have 20 degrees ?

@paolozampini1973 after you update to 3.4, you can try heater feedforward https://docs.duet3d.com/en/User_manual/Reference/Gcodes#m309-set-or-report-heater-feedforward which raises the heater power for higher speed prints.
Alternately you can adjust the heater fault detection using M570 https://docs.duet3d.com/User_manual/Reference/Gcodes#m570-configure-heater-fault-detection but since this is a critical safety feature I would only use this as a last resort. It does allow you to adjust the excursion limit as you requested.

Thanks for the very kind reply
