Duet 2 Wifi

gjameson

I have a Duet 2 wifi about a month old and I has been working great up until this morning. I turn on printer and the board did not connect to my wifi. Inspected it to make sure all connections and jumpers will good, they were. Decided to hook up usb to computer and all of a sudden, the wifi powered up. Before I only had one light on. It appears normal now. Searched the forum and this is what I came up with.

I checked the 5v jumper and it is there also looked at the U3 chip and did not see any damage.

@gjameson
That sounds like a warranty issue. If it turns out the onboard 5V regulator doesn't work. Do you have a multimeter to test?
@T3P3Tony will tell you what to do, to get an replacement.

@o_lampe Yes I would like to get a replacement. Not sure about a multimeter to test though.

@gjameson thanks. The 3.3V and 5V regulators appear undamaged, and I can’t see any other obvious damage. Have you checked the fuses? I notice the fan fuse is 2A, did you change that? Is you PSU definitely outputting the correct voltage?

When was it purchased?

gjameson

Ok this was purchased on January 02, 2022.
It was working for almost a month with no problems.

@gjameson Are you able to answer Droftarts questions above?

Did not change fuse and fuses appear to be fine and unbroken.

Can't say if PSU was outputting the correct voltage but I can tell you that it worked fine for almost a month and the Bigtree board worked great for over a year that was being powered with the ender power supply.

@phaedrux Had a chance to dig into this board today. It had:

A (blown) 1A fuse installed in the 7.5A Steppers & Heaters fuse holder.
A 2A fuse installed in the 1A fan fuse holder

I installed a 7.5A fuse into the Steppers & Heaters fuse holder, and the board powered up and works fine, communicates over WiFI without issue.

@elmoret thanks for fixing it! A number of people including me asked about the fuses, but I guess the OP didn’t check all of them.
