Good morning @dc42,

I don’t think that I did something thing wrong. I connected the fans to the board, the right way around. And it worked after some prints they stoped working. I didn’t change anything on the wiring. Or connected different fans, air pump.

Hey @dc42,

I Just checked it, as I assumed the fan0 and 1 are not working. Fan2 is working.

@dc42 I haven't tested the M106 P0 S1 H-1 jet, but I turned each fan to 100% with the web interface. Only P2 worked. And every fan should be turned on when I start the printer correct ? (at least that is what he did, before it broke. And What he does with P2)
I also heated the hotend and the bed to my normal printing temperatures (also tried test prints) with should turn on the fans, correct ?

@T3P3Tony Hey Tony,
I tested the remaining outputs with all of my fans that I ever had connected to the duet, all are working fine. I don't have any problem. I didn't change any thing on the connections in the last time so I can't tell you why the F0 and F1 are broken.

@PaulHew Hey Paul,

I have tested this settings already and it did'n change anything, the fan0 and fan1 both are not working any more.

@Phaedrux No it is not missing, I have H, H1 and H-1 in the config file. So everything should work like it did for some time before it broke.

Good morning, @droftarts

config.g

Let me know if you can find some thing that is wrong with it.

Hello @T3P3Tony,

I tested two Creality3D DC Brushless 24V Fans, the Creality3d blower fan (24v). They all work fine on the other pins (like always on pins).

@Veti I don't know if the mosfet is broken. And this looks like a difficulte replacement. I just used it normaly and it worked for some weeks fine. But it
gone broken today while normal use. I don't what to break it more because I think there is just a bad connection that could be a easy fix for some one that knows what he does.

Hello Duet Guys,

I'm sad to tell you that my duet 2 wifi broke. The Fan0 and Fan1 connector stoped working while normal operation. I checked the fan and the wireing both are fine. I am on VIN 24V.

I contacted e3d to return the duet. I just have it for some weeks, and there told me I should write a forum post first and get the ok from a forum admin that this board should be returned.

Best Regads,
Veit
