Extruder Fan doesn't turn on automatically above 50 F #43

Closed alcore23 closed 3 years ago

alcore23 commented 3 years ago

Good afternoon,

I had to reinstall my firmware on my MKS SGEN L, which I have installed on and Ender 3, and after the update the extruder fan won't come ON automatically when the hotend is above 50 F.

I see that the Temperature menu now shows Fan 1 and Fan 2 as well, and I can manually turn the fans from this menu option. Fan 1 turns the part cooling fan ON, and Fan 2 turns the extruder fan ON.

I have not changed the wiring and this function worked fine on my older firmware, any recommendations?

Hi! Can you provide your config to me?

alcore23 commented 3 years ago

Yes

Which Marlin Firmware are you running. On mine with 2.0.6 it's working fine. Hotend Fan connected to the E1 heating output.

alcore23 commented 3 years ago

I am using the latest on this repository, which I believe is 2.0.7

you need to set "#define E0_AUTO_FAN_PIN" to "FAN1_PIN"

It's like dimetry wrote. Something in your config wrong.

This did the trick! Thank you very much all.

I was confused because the notes said that -1 would disable it all together so I had tried commenting out that line, but I did not try to assign a value.

I drop the value to 30 degrees as well.
