I can't connect my Duet 2 Ethernet with my network anymore.
Firmware 3.2 is installed via USB and YAT is working.
Problem: non of the LED's (yellow & green) in the connector is on. The cable and the router settings haven't been changed....
Is there any chance that the fault is on my side and not a hardware issue ? How can I test this ?
Thanks for your help
Andreas

Thank you for fast and competent help !!! I'll try to get a new one.

Yes, after M552 S1 YAT looses the USB connection

same with the Ethernet DHCP connection - no answer from the board and no LED on the connector.

Wow, that's fast !!! Thank you for your reply !!
Well, I disabled M552 S1 in the config.g and got a reply on M115 ! see picture
The green 3,3V LED is on all the time , but there is still no reaction on M552 S0 in YAT and no LED on the HanRun Connector.

Hi,
yesterday evening my Duet3D Ethernet board (V1.03) lost its internet connection.
It worked now for 4 weeks pretty well (controlling via web access), but since yesterday I don’t have any access to the board:
1.During some motor tests (all of them worked – no electrical problem) I lost the connection between Webbrowser and the board several times –
after switching off the 24V power supply, it rebooted and the connection established again. After 10 min and sveral (successful) reboots, the board disappeared completely. Both LED’s on the HanRun connector are off.
2.When I connect the board via USB with my computer the 7” display shows the normal surface and accepts input, but nothing happens.
3.The IC on the Ethernet extension boards gets really hot, even with a 5V USB connection to my computer. Is this normal ?
4.I can establish a USB connection between my computer and the board via YAT – but M115 doesn’t give any response
Can you please help me to solve the problem ?
