Fans not working Duet 2 wifi
-
I just bought a duet 2 wifi to use on my CR 10 mini and I cannot get my hot end and part fans to work. I first tried plugging them into the always on port and that didn't work and then I tried fan 0 and 1 and still nothing. The jumpers are on the vin and V_fan
-
check the fuse.
did you get the polarity correct? if the fans are plugged in the wrong way it can damage the duet.

I had a strange incident of a fan not working recently. The cooling fan on my hot end stopped working after running ok for some time. I took it off and connected it to an external power supply and it worked fine. I tried it on an 'always on' connection on the Duet and it still did not work. Fitted a new fan and it now works as before. I do not know what has gone wrong with the old fan for it to stop working with the Duet board.

@Veti yes

@jmshep I've tried multiple fans to check. The only thing that I haven't tried is to check the resistance, continuity, and programming.
-
does the fan spin if you connect it directly to the power supply that is connected to the duet?
-
@Veti yes it does.
-
@Veti im going to check the resistance and continuity tomorrow

Don't forget that the fans used for this application are usually 'brushless' and you will probably get a very high reading with the probes connected one way and infinity when connected the other way round.
BTW my fan issue turned out to be a connector problem.
