config file editing
Hello everyone... Not understanding how to edit config file for 4028 parts cooling fan
I've looked at the documentation and it doesn't make any sense, I moved the blue wire to the negative side of fan 0.. but I don't know how it's supposed to look in the config file

Not understanding how to edit config file for 4028 parts cooling fanYou shouldn't, that's probably why 🙂 Everything custom is done in the USER OVERRIDES section in printer.cfg, it tells you exactly what to do in the 4028 guide on os.ratrig.com: https://os.ratrig.com/docs/guides/4028#25khz-pwm-signal. There are no includes for 4-pin fans at this moment, except for the few boards that have dedicated 4-pin fan headers (such as the SKRat and the Manta M8P).

4028 server fans are becoming a popular option for part cooling because of their light weight and great pressure and flow rates. In this guide we'll go over how to connect one and use it for part cooling. 4-pin fans usually aren't used in 3d printers, and many boards only provide 2-pin ports, but fear not! There's always a way.
