@phaedrux said in Duet 2 Ethernet will not boot -> need WAC:

Can you be more specific?
Do any lights come on?

Yes, the LED VIN, +5V and +3.3V were on.

Have you connected it to USB?

No, as I never used the USB connection before.

When and where did you purchase it?

I bought it at Filafarm on the 26th of August 2021.

Please follow the troubleshooting steps here and let us know how it goes.

As it is really not my first Duet Ethenet Board I used, and the other one worked without problems, I did not investigate any more. Furthermore the machine is located at my customer's place so I can not go there just for testing..

Hello,
I used a Duet 2 Ethernet in one of my machines but it simply did not boot and I thus got no connection. After changing it by another one everything was fine.
Please send me a Warranty Authorisation code.
I built up about 10 similar machines in the last 3 years and I did not have this problem till now.
Thank you very much in advance!

Hello together,
I developed a system with 7 stepper motors and wanted to share my results according EMC.
In the picture below you can see the drawing of the motor cables i used for the EMC Test and the results (courtesy of Bureau Veritas CPS Germany GmbH). The pigtails of the cables are screwed into the steel plate, directly next to the Duet-Board. With this setup I got the best results in the laboratory (test method EN 55016-2-3:2017) and stayed below 40 dBμV/m / 47 dBμV/m, which is necessary for industrial machines.
Of course you allways have to make your own EMC tests, but maybe this information is helpful for somebody.

Hello david,
