Expanding fans on radds for part cooling.. Can it be done with repetier firmware?
I'm in the process of getting my qidi dual printer switched to something other than sailfish (what a piece of proprietary trash). I want to go with radds since in need two fans that are automatically cooling the hotends. Now can I pin out an extra fan? What would I need hardware wise to drive one or two manual control fans? I saw something about a D9 pin, but what do in use from there?
