Duet 3 6HC not communicating
-
Hi All,
We ordered 2x Duet 3 6HC's from E3D here in the UK in on 24/04/23.
We fitted the first one into our Custom built control panel, powered on okay but no communication to our raspberry Pi 4 Model B.
I have since swapped to the second board in our order and that is working fine.
I have plugged the board into my laptop and I don't get the usual pop up to notify me I've plugged in a Duet.
Following the https://docs.duet3d.com/User_manual/Troubleshooting/Duet_wont_respond page.
I confirmed the lights whilst it was plugged into my PC, 5V LED, 3.3V LED, The Diag light was flashing on & half. The board doesn't appear in the bottom right and I don't find it in the "Ports Com and LPT" in device manager.
I have since done a Erase of the firmware following the instructions provided, confirmed no firmware via the diag Light glowing.
Then plugging back into my computer I do not see it in the device manager under Bossa port.
I contacted E3D support but they have said to come here and ask. What should I do next?

@JimmyEvo3D It sounds like the USB port is not working, though it is getting power through it. Can you take a closeup picture of the PCB connections behind the USB port, and post it here? Is the Raspberry Pi acting as an SBC (ie connected to the 26-pin SBC header with a ribbon cable) or just connected by USB?
Please can you also try connecting after removing the SD card. Also check if the Reset switch is stuck in (though I wouldn't expect the Diag light to flash if this was the case).

Unfortunately the MCU on the 6HC goes into high-speed mode when in Bossa mode (I've no idea why Atmel/Microchip chose that) and in that mode it is very fussy about the USB port it is connected to and the cable used to connect it. So try a different cable and/or USB port.
Additionally, if it is a version 1.2 6HC board then it won't announce its USB port unless the device it is connected to provides 5V power. So it won't announce its USB if you connect it to a hub that has power switches for the port unless the switch is on. Check that the 5V USB LED is lit as well as the usual 5V LED.

Hi Both,
Thank you for answering. I will check both of what you've said and come back with an update.

I don't have a reset button I believe? I think my model I have to connect the two pins together with a jumper. Here is the photo of the pins into the USB
@dc42 The USB Power light is illuminated which is in the photo above. As for cables I have used two different USB-C cables and the two different USB ports on my laptop. Once my colleague is available I will try it on his desktop instead to see how that goes.

If you have a USB hub give that a try as well.

Hi, I tried the USB Hub but that doesn't provide constant power so the board doesn't have enough voltage to turn on.
Is there something I'm missing in how to set it up on device manager as on windows 11 the bossa port doesn't come standard. I have added it to the list but it still is never appearing with all of the combinations already carried out.
Also I know i have the Duet Driver as mentioned in the link further up as i have used this laptop before to communicate to plugged in duets but i wanted to confirm i had the most up to date one. I cannot find a download for it?
Anyone have any further suggestions i can do?

@JimmyEvo3D Can you test your USB connection by plugging it into your other board? I think you should be able to connect to it even if the Raspberry Pi is connected. Just be careful of ground loops, ie connect using a laptop that is not plugged in to mains power. See https://docs.duet3d.com/en/User_manual/Overview/USB_ground_loops
If that works, then I think we can safely replace this board under warranty.
