BTT E3 RRF 1.1 PLUS E3 RRF IDEX 1.0 FAN0 AND FAN1?

[cowbite]

Hello,

How do you enable fan0 and 1 on the idex board? I've plugged fans into them and tried to spin them up via the LCD but they don't do anything. I'm guessing there is a firmware setup necessary for this?

 

Any help would be greatly appreciated as I have found nothing on the internet about this.

 

Much appreciated.

Hi, yes. You need to define them in the pins file according to the fan pins of the IDEX board for them to work. like this. https://github.com/bigtreetech/BTT-E3-RRF/blob/master/BTT E3 RRF V1.1/Firmware/Marlin/Ender3/Marlin-2.0.7.2.x-E3-RRF/Marlin/ src/pins/stm32f4/pins_BTT_E3_RRF.h
