Hi. I have 1 hotend, 1 heatbed and 2 fans. How should I connect the fans on RAMPS 1.4(as hardware) and what should I change in Marlin so that the Hotend fan will run at full speed over 50 degree Celsius and turn off below 50 degree Celsius and the cooling filament fan or the prin fan to be turned off when it's not printing, 20% power on first layer, 70% power to the second layer and full power on the third layer. I took a look and there is no option in Malin for this. It's only EFB, EEF, EEB, EFF but no EFFB.
