Duet 3 Mini 5+ unable to connect via browser

@gloomyandy yeah, still the same problem.

Did you start with the very basic config.g file that came on the SD card or did you replace it?

I received mine a week or so back and after using a terminal program to configure the WiFi and editing the config.g to enable WiFi it worked without issue.

@LevelFun, from YAT please send:

M20 P"/www"

to check that the /www folder can be accessed and get a listing. If that command returns an error, send M21, then send M20 P"/" and report the results here.

@dc42 Yat reports the following:

I've tried multiple SD cards all within spec. I know I must be doing something wrong, I just don't know what

[dc42]

@LevelFun, I don't think you're doing anything wrong, I think the SD card interface isn't working on your Duet. We're using a new (to us) chip to protect the microcontroller from ESD on the SD card interface, and on the first production batch we had a few boards on which not all the pads under that chip were securely soldered to the board. Unfortunately it's possible for a pad to be making contact when we test the board, but to lose contact when e.g. the temperature changes. I think that's what's happened in your case.

Please accept my apologies for this inconvenience, and ask your supplier to replace your Duet. You can point your supplier to this thread as authorization.

[LevelFun]

@dc42 No worries. I purchased it from Filastruder here in the US. I'll message them this evening pointing them to this thread per your instructions. Thank you for your help!

[LevelFun]

@dc42 well, I returned the faulty board per your instruction. Filastruder (my supplier) was quick to respond and send me a prepaid label. Sadly, they say there is no current stock. Is there a time frame as to when the Duet 3 Mini 5+ will be back in stock for US retailers? I feel like I'm getting the crap end of the stick in this situation (ie - buying a new board, having the new board be faulty, having an offline printer until I receive a replacement, having no current replacement available). Isn't there anything else that can be done by the Duet3D team to help make this right?

[Phaedrux]

@LevelFun Sorry about that. Unfortunately they are being sent out as fast as they are being produced. Hopefully it won't be much longer.

[LevelFun]

@Phaedrux Any updates on when stock is being sent out? Still awaiting the replacement for my faulty board. Thanks in advance.

Request that your original board be repaired since it is just solder joint failures. Maybe that is quicker than waiting for a repalcement?

[LevelFun]

@timcurtis67 Were that an option to begin with, I would have, but the only option provided was to return for a replacement.

[T3P3Tony]

@LevelFun the next run is starting this week (delayed by about 3 weeks for various reasons). We have been trying to give all our resellers a chance to purchase boards as well so we have not been able to send Filastruder any recently.

We will be sending them some ASAP and I am sure they will be sending you a replacement straight after that!

[pkos]

@dc42 - is there a way to tell based on a serial number or any other marking if my board has the same problem?

It's a new printer that's been operating for something like a week. It did a couple prints, but mostly around calibration, so nothing too long.

Yesterday, I launched a 2 hour print and after about 70 minutes, the printer froze in place and DWC reported it couldn't find the gcode file anymore.

After a reboot of the machine, I couldn't connect to it anymore. YAT showed an IP was properly assigned, but I couldn't list any files on the SD card.

Interestingly enough, when I ran M21 - I got a positive answer that the card was mounted and I could again run the printer.

I'll be doing more stress testing today, but wanted to see if there is another way to be sure that's the issue.

[dc42]

@pkos, it likely has the same issue. I'm sorry for the inconvenience, and I authorise a warranty replacement.

[pkos]

Understood. I'll talk to E3D to get a replacement.

Thank you

@dc42 Hi unfortunately my Mini 5+ appears to have the same problem as Pkos... earlier today it got stuck and was no more reachable... after many tries of power off finally it came back... but by time to time it does not list the files (system / marco) and does not respond anymore to http... sad ...

[Phaedrux]

@oc_geek Would you be able to start a new thread so we can do some basic troubleshooting and if required use that thread as your warranty claim? Thanks.

[pkos]

Not to necro the thread too much, but is there anything a person with a hot air soldering station can do?
It seems like the stock for those minis won't be available again for another month or so.

Our assemblers are currently building and testing a large batch of Duet 3 Minis. Deliveries to our resellers should be in full flow next week. They have been using our second-generation CAN-based Automatic Test equipment since the start of this week to speed up testing. This is the prototype:

The lid on the top right holds the Duet 3 Mini under test down to make contact with the pogo pins. The power resistors at the top provide loads for the heater/fan outputs, and the bank of inductors on the left simulate stepper motors without producing noise. The Duet 3 Mini at front centre runs the tests. At the back (not visible) are CAN-connected boards that measure motor currents and I/O voltages. Ignore the MB6HC board at the front, I was using it to adapt the ATE firmware to test MB6HC boards too.

Yes, all it needs is a no-clean flux pen and hot air equipment. If you were in the UK, I would have volunteered to repair your board already. I have repaired about ten pre-production boards in this way.
