Is anything on the Duet getting hot?
I incorrectly assumed that would be part of the guide, should it be?

I don't think it is - and yes, it would be worth adding, especially in the case of the green LED not lighting up at all or flickering.

I checked after your comment, and it isn't. I didn't include it in my response, on the incorrect basis that it'd be covered by the guide - thus the suggestion to add it.

@bearer @dc42 If it is hot, what would be the correct course of action? Weep? Let me know and I'll update the guide.

Unless its the SD card or the Ethernet module that can be removed its off to repairs as the part likely has an internal short and needs replacing.
-
Alright, perhaps the best course of action at that point would be to come to the forum and seek further assistance.
-
Thank you @bearer I have tried just about everything on there with no luck.
-
@mficken and nothing is getting warm?
Get some high res pictures of the board and lets see if we can spot any damage.
-
@Phaedrux
maybe adding that a picture would be helpfull if turning to the forum? -
@dc42 Yes, I plugged it in and some parts got hot very quickly. Specifically something labeled U3 which got very hot after only a few minutes.
-
Then make sure the get a close up that when you take a picture.

Here is a picture of the entire board as well as one close in on U3
-
Looks like there might be something on U3, its usually easier to see though, if you see something clearer in different angles of light please update.
in any case its over to the duet people for now.
-
@bearer I saw that, it is more visable at certian angles but it is hard to tell in those pictures. I took them on my phone but my camera is charging now so I will try to get a better angle after it is done.
-
@dc42 Here is another picture that may be higher quality but it is still difficult to see the mark on U3
-
@dc42 The topic seems to have slowed down. I was wondering if you have a recommendation for next steps. Is there something else to try or should I file a warranty claim?
-
@mficken Sorry no-one got back to you; the forum has been very busy lately, like people have got time on their hands or something!
It looks like the 3.3V regulator U3 has failed (dim LED, things getting hot). I'm happy to approve a warranty replacement, assuming the board is less than 6 months old.
Please contact the place you bought it from, and follow their warranty process. They will ask for evidence, so please supply them with a link to this forum thread. If you bought it direct from us, our warranty terms are here, and a link to the warranty form is at the bottom of the page: https://www.duet3d.com/warranty
