So I posted in a 6mo old thread to get help and need an answer now. I have a machine that has 2 layer cooling fans. I'm using Cura 4.4.1 . fans havent been engaging, thus giving me crappy quality. discovered that I have to set the Cooling Fan Number to 0, even though one would figure if ya have 2, put 2. so I did. and obv that messed it up apparently. yay Cura. so I set the number to 0. no difference, wont do another print til I get an answer. I really dont wanna have to turn em on in the tune settings.
