Set minimal fan speed for chamber fans but keep auto speedup
Hi all,
I am looking for a way to set a minimal speed for the chamber fans, but still have them to automatically speed up when the chamber temperature rises.
Background is, I have the printer ventilated outside and would like there to always be a slight negative pressure in the enclosure.
Is there a way to maybe achieve this in gcode using the layer change custom instructions? For example, can I set the chamber fan to 10% if the temperature is below the nominal threshold, and set it to auto once the nominal threshold is reached?
Thanks!
