I have been searching the latest version of firmware to find where to control the two micro fans for my dual extruder heatsink.
I cannot find a PID solution or a bang bang solution
But, where in the firmware do you control, modulate voltage to these fan’s pins??? config.h, config.h adv., pins??? I can’t find it!!!
The problem is not how to control fans 0 and 1 with the m106 s255 and m107 commands. I want to control the 5v micro fans.This fan needs to be slowed down just a hare, but it is cooling my hotend too much. This will reduce the life, and cause an inconsistent temp for printing.
