Duet 3 DCS not start, no 3.3v led, board Ok??
-
Let's back things up a bit and try to verify what is working in isolation.
First let's test the Pi. Connect only usbc power, hdmi out to a monitor, and a usb keyboard/mouse, and ethernet. Try with the DuetPi card you have prepared, but it may also be a good idea to test it with a stock Raspbian image from the Pi foundation directly.
For the Duet3, we can also set it up in standalone mode. First connect it to a computer with a USB cable. No SD card present. See what LEDs light up on the board. Try to connect to it via USB terminal software like YAT.
For more steps to check, you can follow along with this guide: https://duet3d.dozuki.com/Wiki/What_to_do_if_your_Duet_won't_respond
If the board appears to be responding check the installed firmware version with M115.
you can then setup an SD card with a basic config file set generated with the online tool.
https://configtool.reprapfirmware.org/Start
The SD card file structure is detailed here: https://duet3d.dozuki.com/Wiki/SD_Card
Putting the SD card into the Duet and connecting ethernet and usb power should let it boot up the config file on the SD card and enable the web interface. You can then try connecting to it at it's IP address.
If both pieces of hardware are working independently you can then work towards getting them communicating. They will need matching firmware versions.
Update the Pi with sudo apt update && sudo apt upgrade.
Update the Duet by uploading this zip file to the system tab in the web interface.
https://github.com/Duet3D/RepRapFirmware/releases/download/3.3/Duet2and3Firmware-3.3.zip
Then you can connect the ribbon cable, remove the SD card and ethernet cable from the Duet, and start them up.
At that point you should be able to follow along here: https://duet3d.dozuki.com/Wiki/Getting_Started_With_Duet_3
Let us know how far you get with each device in isolation.

@phaedrux when I plug it into computer with provided cable I get a solid red 5v and a solid red usb? Light between the miro port and SD card slot. I try to install drivers and it ends up an HID... I'm on my surface book and use a good USB c Hub and have bus power via portable charger while data from pc. Tried without also. Same thing ends up surfaceucmucsihidient device
I got duet 4 to boot up fully into duetpi after I
hooked up a monitor and keyboard.I did that test in trouble shooting where you connect pin 19 and 21 and I copy paste the command and got the same results.
-
@chanabra RPi4 fully booted up cannot start DCS... Time out
-
@phaedrux In any case there is no green LED for 3.3V ever
I have also now just tried on my Linux laptop and there is no /dev/ttyACM[number]
I am about to try the erase options....
please, please, advise. -
Yes you can try the firmware erase jumper on the Duet 3 to clear any firmware and make it programmable. Use Bossa to flash firmware 3.3 on it.

@phaedrux I decided to take thing from the beginning as I purchased the board from Tim and was advised not to miss any points and be more articulated.
The RPi4 4gb connected with USBC power and HDMI out to monitor and a usb keyboard/mouse and ethernet works just fine.
Duet 3 in standalone mode connected to a computer with a USB cable , (I also have a 60W PD Portable Charger I used to supply my laptop power simultaneously after trying on a full charge, as well as tried different micro usb cables) and no SD card yields the following LED: USB red LED between micro usb female port and microSD slot as well as 5V. No 3.3V. No matter what 3.3V is nowhere.
Following your what to do if your Duet won't respond get's me to: If the red LEDs are lit but not the green 3.3V LED then most likely there is a short between the 3.3V power rail and ground.
However, I am at the stage where I simply have a Meanwell 24V PSU hooked up to VIN and do no get 3.3V.
Attached are pictures of this:
- Connected to Laptop, only the 2 red LED 5V and USB LED.
- Connected to Laptop w/ Portable Charger adequate enough to charge laptop, only 2 red LED 5V and USB LED.
- Duet 3 6HC only connected with + / - 24V Meanwell PSU
- Clear shot of Duet 3 6HC with the same configuration as 3 just a straight shot of the board.
Also I attempted the erase jumper multiple times as per the link provided "What to do if your duet wont respond" and I cannot get it to have more than the 2 LED: 5V AND USB and it shows as surfaceucmucsihidient regardless of my appropriating the correct driver to it.
On Linux there is no /dev/ttyACM[number]I believe there is a problem with the voltage regulator providing the 3.3V the board needs.
I am going to reply to this post with my cell phone to make it easy to post the pictures .
Please let me know if I missed any of your steps or where I should go and what I should do from here - I need to make sure i follow procedure.
Thanks for your time Duet team and wise contributors.

Jk about picture 4. File too large and is very redundant as you can see the board in picture 3.
I await further instructions.. -
Thanks for the granular testing. It's much clearer.
Can you get a few well lit close up photos of the board? Maybe a few photos showing the 4 quadrants?
If the 3.3v regulator is damaged/failed it may be covered under warranty. When and where did you purchase the duet?
-
@phaedrux yes of course
Here you go. It may be worth mentioning I have a bench power supply and could, per instruction only, attempt to supply the board with 3.3V directly if that is a thing. The board was purchased through Filastruder and I have only good things to say about their service.
-
@Phaedrux the board from filastruder was their order#70861 placed on May 15.
I've been slowly finishing my printer and getting parts together and apologize its just now I am noticing and addressing this..Thank you again for your time and assistance
-
@phaedrux if you want a close up of something in particular let me know.
-
@chanabra said in Duet 3 DCS not start, no 3.3v led, board Ok??:
if you want a close up of something in particular let me know.
The large chip between the SD card socket and the reset button please. Does it look damaged?
-
It does not but what do I know.
-
I think there is a scorch mark right above the 3.
Please send an email to warranty@duet3d.com and CC your reseller. Include a link to this forum thread and the details of your original purchase. You'll receive a reply with a form to fill out.
-
@phaedrux email sent .
Here is another shot with a bit of zoom.
I am not sure what I was looking for and looked beyond that mark initially because things like the 'Pin 1: Indent' threw me off.
