Trying to get 2 fans to go at different speeds.
Hello!
First let me say that I love this Software. It has helped me so much.
I have a CR 10. I installed a Micro Swiss to it and the Grill fan is cooling too much at 100%. I took the grill fan off the always on connection and put it on the second fan control pins so that I can lesson the speed so that it can reach higher temperatures. It's working but I'm having a hard time getting the 2 fans to go at different speeds and a lot of the time just 1 fan will work or both fans just blow at the same speed.
I'm very new to all of this so an overly simplified explanation would be appreciated. : )

Did you copy new PID values to eeprom so it gets used? Also what is dramatically fluctuation for you?
Depending on what parts get cooled by the fan you may need more power. On the other side if you exchange a low power cartridge with higher power cartridge same PWM frequency will give much more move so swings are much too high then. In both cases you need to adjust PID to swing less.
When I try to initialize EEPROM on the screen it is acting like it wants something on an SD card. A firmware update? I do not know how to change the configuration.h file.

shows details on M301, but M500 should normally save it. Check with M503 what the currently values are to verify. Do same also after printer reset to see if it was permanent.
I geuss I should get a new board for the CR10. It has one of the old Creality circuit Boards in it.
