Dual Cooling Fans SKR2 Ender 5 Plus

Posted · Dual Cooling Fans SKR2 Ender 5 Plus

I currently have an SKR2 in my Ender 5+.


I have 2 part cooling fans wired to the Fan0 and Fan1 ports on my board. I have been trying to configure Cura to control both fans during the coarse of a print, but I haven't been able to figure out how to configure this. Can someone please point me in the correct direction?

    As far as I know the cooling fans are configured to each extruder.  When an extruder switch is called for then the cooling fan switches.  If there is no second extruder then the second fan (Fan1) won't be controlled.  The speed of the second fan wouldn't be accessible without a second extruder.


    You could do it with Search and Replace.  If you know what layer you want the second fan to turn on then:

    Search = ;LAYER:30

    Replace = ;LAYER:30\nM106 S255 P1

    then another Search and Replace to shut it off

    Search = ;LAYER:35

    Replace = ;LAYER:35\nM106 S0 P1

    Search and Replace accepts multi-line strings with the commands separated by "\n" (backslash + lower case n)
