Multiple Cooling Fans

Hi
I am looking for some assistance with setting up S3D and my Duet Wifi, specifically the cooling fans.
I have 3 PWM fan outputs on the Duet and am running them as...
Fan0 Part Cooling Fan Left extruder
Fan1 Hotend Cooling Fan (comes on by its self with temp above 45degC)
Fan2 Part cooling Fan Right extruder

My question is how do i tell S3D to switch on left or right fan depending on the Tool that is in use.
Is there a way to set up S3D to use Multiple cooling fans?

Thanks

Re: Multiple Cooling Fans

You could make use the scripting options in S3D to do this

{TOOL0REPLACE "M106 S0" "M106 S0 T0"} ; tool 0 uses fan 0
{TOOL1REPLACE "M106 S0" "M106 S0 T2"} ; tool 1 uses fan 2

More info about those commands here:
