Board unresponsive



  • Hey guys, first off love the duet wifi I have been using them on my other 2 printers for a while now and they are heads and shoulders above the rest I won't use anything else at this point. So I was told to post here by the folks at filastruder, I bought a duet2 wifi and duex5 on like Feb 8th and just got it this week, I had it up and running, then I added the BL touch probe and had it working fine still. I hadn't even done the first test print as I was getting the multi Z motor leveling working and once I got that working I went to do a "Self test" macro for the probe (M280 P7 S120 ; Send PWM channel 7 the S10 (angle) command) and then the printer turned off and has remained since.

    I removed all the stuff connected to it and tried to just run it with only Vin 24V and all that happens is the Vin light turns on but nothing else was responding at all. I followed the trouble shooting guide on there and it said to try and connect it to the PC but then it just does nothing and nothing pops up and no lights come on.

    I don't know what the next step here is maybe there is something I am missing but to my best approximation it seems toasted. The guys at Filastruder told me I had to post here to try to do any kind of troubleshooting / warranty stuff.

    Thank you for your time



  • Could you post a clear, well lit photo oof the top of the board, especially the area around the fan connectors, please?



  • Sure thing,

  • Tim here, from Filastruder. There's a hole in your 5 volt regulator, the part above the fan connectors. ICs don't work well with holes in them, it lets the magic smoke out 🙂

    Generally this happens when there's a short from Vin (12v/24v) to +5v in the printer wiring. I'll defer to @dc42 or @T3P3Tony on how to proceed.

    oh WOW I cannot believe I didn't notice that until just now. Is this a component I can replace if I know someone who can do small scale soldering like that?



  • Yes, if you know someone that can do hot air work. Other options are warranty coverage (unsure if this is covered, dc42/Tony would have the say), or repair through Filastruder (~$20).



  • Well awesome you guys are the best, how long would repair through filastruder would be? Honestly if its fixable and not a whole hassle I totally would not mind spending 20 bucks and y'all are close I'm in Florida.

    If the board is within the warranty period, then it's covered for that fault. After 2 years of shipping many thousands of Duets and seeing zero failures of that chip, we've seen several in recent weeks and we don't yet know the cause. Possibly a substandard batch of chips.



  • Okay awesome, Its not even 2 weeks old yet so it should be covered then



  • Also can I just say @dc42 I have been super impressed over the last few months since I have joined team Duet how awesome the support here is


  • administrators

    Thanks for your kind words, and for buying a genuine Duet!



  • @dc42 So I sent back the broken board already, but I actually went ahead and started testing the Duex5 that was connected to it during the failure with a different Duet2 from one of my other printers and it seems none of the drivers want to work. Any ideas on troubleshooting or is the duex5 probably dead too?

    Edit to provide more details: When the board is connected to the Duet2 and powered on no lights come on, but the 12V regulator is still regulating the 24Vin to 12V for the fans. When I go into the Settings page on the web interface it says "Duet WiFi 1.02 or later + DueX5". When I try to use any drivers to run a stepper motor it simply does nothing. The thermistor connectors work and show data, fan controllers seem to work fine as well. I did not test the heaters, but the PWM all seem to work fine as by BL touch is hooked up to PWM5 and it did its self test when I powered up the printer


  • administrators

    That's an odd fault. The 3.3V feed to the DueX must be OK because it the Duet knows it is there, so the I2C expander chip on it is working. Normally I'd say that it looks like a missing VIN supply, but you report that you have a 12V output from the onboard regulator, so VIN must be present.

    Please send M122 and report the output here, in particular the status of all the stepper drivers.

    How did you try to use the stepper drivers on the DueX5?

    I have 3 of the drivers ( 5 6 7 ) along with 2 as Z motor drivers and I have them mapped but when I try to do any Z moves only drive 2 moved

    Please post the config.g file.

    Thye M122 report looks OK, all the drivers appear to be responding to SPI commands.

    Your M584 command is in the wrong place. Please read the section on order dependency in the entry for M584 on the GCodes wiki page. Also the section flagged Important in bold.



  • Yup there we go turns out I am just stupid 😅 😅 😅 thank you so much
