Do I have a bad expansion board?
-
I recently purchased the Duex 2 and Duex 5 Expansion Board - Duex2 board for the Duet3d wifi. I now have 3 of the fan ports that have stopped working. Yesterday, I was watching one of the temperature activated ones and it just stopped and I can't get that port to work again. Ports 3, 5 and 6 are the ones I can't get to work. All 4 of my fans function when I have them hooked up to functioning ports. So the wiring for the fans should be good. I've changed my config.g file to point to the working ports up until number 5 quit. It's still in the config but I can't get the fan to work. It should start with the M106 command but it doesn't.
Here is a pic of my board.
here is my config file.

It doesn't look like my config file got posted. Here it is again.

Are they ordinary brushless fans, or something more powerful?
Is there any sign of damage to the small 3-pin mosfets next to the fan outputs?

I don't know if they are brushless or not. They are 30mm 12v fans. Most of which I got from the filastruder company so I would think they would be compatible. I don't see anything on the 3pin mosfets. I think those are the little chips just above the outputs that have 2 little pins on one side and 1 pin on the other. Nothing looks charred or anything.

Any ideas?

I think your expansion board may be faulty. Please ask your supplier for a replacement under warranty.
