Hi to all,

I have Duet board 0.6 and I want to add fan controlled. I can use expansion header pins in duet board 0.6?

There is already one controlled fan output on the Duet 0.6 so I presume you mean you want to add a second one.

You would need to pick an unused heater pin on the expansion bus, connect an external MOSFET to it to drive the fan, and rebuild the firmware with a modified Pins_Duet.h file to allocate that pin to a fan instead of a heater.

Pins_Duet.h is at [github.com]. Documentation for files in the /sys folder of the SD card is in the wiki at duet3d.com.
