Hello,
I have a printer that has a SKR Turbo, Marlin 2 and it has 2 hotends and 2 part cooling fans.
Can someone share a link with me on how to connect the second part cooling fan so it turns on when the second extruder feeds?
I think you need to use the FanMUX. If there is a tutorial around about how to use the fan mux .. I just want to add a second fan, not 3, 4, 8, 16 but still it seems the fanmux is required.
Currently I have it marlin configured fanmux pins configured...
#define FANMUX0_PIN P1_00 // PWM
#define FANMUX1_PIN P0_26 // PWM
#define FANMUX2_PIN -1 // Removed comment on 9/28/2020
Where fan1 is connected to P1_00 and fan2 is connected to P0_26 but this, of course, does not work.
