You are genius.

For the PI, it was no problem to flash the board. It's running now. You have rescued me!
Big thanks!

@jens55 same problem here. It's very difficult... the PH Crimps are way better

It's a small board but maybe it would be better to use a slightly bigger board with bigger contacts...
It will also be better for me and my big fingers...

@phaedrux
Maybe. I tried 4 different Laptops. Maybe something with a Windows configuration.

Lessons Learned: better do it with the PI

Pi was successfully connected to the board. I was able to see the settings and tabs...
That's all...
A fast death

@phaedrux
Yes. But this didn't work.

The 5V LED is Red, the 2.3V LED is green, die LED namens "Status" is glowing red (mich darker than all the others) and the USB LED is Red.

Today another PC, same procedure. "Unknown USB-Device (Error when requesting a device description)"

@phaedrux
I did it wrong.
Started all and used duet2and3firmware-3.3.zip via the Webinterface...

The mentioned error is from Windows when I plug in USB. The PI can't connect.

I tried it with your manual but Windows don't recognise the board. "Error reading device". So no Com-Port is available...

Hello all,

I have my Duet3 freshly connected today. I run the board in conjunction with a Raspberry.

The board started and everything was ok so far.
The first thing I did - software update (the lastest stabile). So took the current software, uploaded it and let it install. After that it didn't go any further..

The web interface of the Rapsberry starts, but gets no connection to the board.
Also over USB no connection is to be gotten.
Different cables and even a "reset" according to the manual (https://duet3d.dozuki.com/Wiki/What_to_do_if_your_Duet_won't_respond).

It stays at "Error Reading device", so no com port or similar.

Advice on how I can get the board back to life?
