Hot end fan is wired to
Where do I find the pins file?
I don’t see that of the board. Then I may be blind lol
This is identical to my board.
And there’s nothing printed on the back.

you dont do that, the part fan goes to the main board, and the heatsink fan goes to power supply
YOUR PINS ARE FINE, ITS YOUR WIRING.and more letters
That’s how it was wired when I got it and it worked good with the original firmware.
I just added the part fan.
I will change it if I have to but I have a Bad problem of Things working the way they are Suppose To.
But then I’ll still have to sort out the fan 1, Fan 2 situation.

the part fan is the upgrade, they dont come with a part fan if you just change the wires it will work
I realize the upgrade part,
Just trying to find out why it doesn’t want to work now with the different firmware.
Painfully it helps me learn how what and where to edit.
