Out 7 is the pin question -(not called out- switched to out 9)

I'm sorry, but I am having a hard time parsing what this sentence means. Are you saying you are connected to Out7? Or Out9?

I'm sorry- juggling a few different tasks a responding in between- Hope this clarifies:

I am using Out9 as I originally intended to use Out 7 since out 7 is always on now.
since out 7 was now open and always on I attached a cooling fan for the duet in that position. out 7 is not called out anywhere in my config.g

Summary:
-out 7 originally used for a thermostatic controlled E1 cooling fan
-E1 cooling fan started to run constantly whenever board was powered up.
-Switched E1 cooling fan to out 9 (updated config.g as shown above)
-Added enclosure fan for board and plugged into out 7.

I don't understand why out 7 is constantly providing power.

Phaedrux

If you define out7 as a fan are you then able to control it?
Are you sure you're connected where you think you're connected?
Photo of wiring?

Out7 was previously defined where Out 9 is shown in current config. for thermostatic control and it was always providing power.

-Out7 is not defined at all in Config.g and is always on providing power.

Please see attached pictures (NOTE-out 7 is show open with duet cooling fan removed)

Thanks for the better picture.

I'm not sure why out7 would be powered constantly, other than maybe a mosfet failed on?

@Phaedrux

Not sure. Is this something that would be covered under warranty? (ordered board on December 4th). Thanks.

Phaedrux

@ekrop If that's the case, yes. Will see what the more electrically minded think.

Good morning to all.
Sorry for my english.
I monunt Duet2 + duex5 on my trex3+, configure firmware with originals parameters, but i can't do good prints.
My printed parts are full of ghosting, blobbed angles....

what parameters do you use?
thanks

@polbofree You should probably start a new thread.
