US Repair service?
-
You have two boards (both tested at factory) one never used, that are not communicating via USB, and your conclusion is that both are bad, not that you have done something wrong?

@elmoret Ok a prefect storm of stuff.
Duet 2 Wify was in a 3D printed case that was destroying the USB cables as I used them. Enlarged the hole and the USB connection started working.
Duet 3 6HC board is still inoperative.

@fredsairplane said in US Repair service?:
I flashed an SD card with the initial network configuration of DHCP and expected it to appear on the network.
I'd repeat this step and make sure it works. SD-card needs a special formatter and it has to be FAT16/32
For more specific help, we'd need more info about LED status, onboard voltages (5V, 3.3V present?) etc.

Ok I blew right past these steps because I did the erase procedure.
At this point I absolutely need the USB port to function.
Had I not done the erase procedure I could have tried a Raspberry PI communicating via the SPI data lines.
I expected the Bossa Port device ID to appear in the windows Device Manager after erasing the device.
At this point I need to know if there is replaceable chip between the USB port and the CPU to possibly resurrect this board. So that it appears to any USB host as a Bossa Port to reload the correct firmware.
-
Or per my original request is there somewhere I can send this not inexpensive board to be repaired?
-
@fredsairplane when the firmware is erased the SAME70 chip on the MB6HC goes into high speed USB mode and is very fussy about the USB cable and USB port. Cables that work with Duet 2 don't necessarily work with the MB6HC and USB extension cables in particular don't work. So try a different USB cable, and a different USB port on the PC.

A USB hub might also help.
-
And an independently powered USB hub at that
-
Ideally, but people have reported good results with just a hub.
-
Ok a USB3 hub allowed me to see the Bossa Program port!!! Standard USB hub failed...
Now trying a firmware upgrade configuration generation.
