I am following your videos to set up my boards, but i have lots of questions.
i am trying to use all 4 hotends that this board supports.
this means, i need 4 hotend cooling fans, and 4 print cooling fans.
1. to be clear, this is the fan for cooling the hot end, not prints, right?
2. If you are moving PA6 to PA5, this would leave me with 3 fans, not the 4 i need, how do i use all 4?
3. how do i set up the 4 other fans? i dont care which ports go to hotend cooling, and which ones go to print cooling, but i need 8, 2pin fans going, preferably controlled when in use, not just on all the i see there are 3 sets of 3 pin, and 3 sets of 4 pin fan ports next tot he 4 covered in this video, but i need sets of 4 to go with all 4 hot ends. How can i make this work with 8 controlled fans?
BTT seams to have over looked they have things in 4s, not 3s.
