@phaedrux no. Doesn’t show in device manager. I just got second duet 3ht board today. This one works just fine. There’s definitely something wrong with first one. How can I warranty it ??

@phaedrux same sd card with original content installed in duet 3d. USB plugged in to computer. Raspberry pi disconnected. 5v and 3.3v led lit. And led by micro USB port. Status light dim. No communication over yat.

@rushmere3d I tried both ways. Nothing seems to work. Tried with and card in duet. No communication with the board also. Voltages on board r good. Thinking mpu is fried on board.

@phaedrux
Operation failed (Reason, Could not connect to Duet Board is not available (no header ).

That’s the message from pi

Hi guys

I just plugged in my new board. Sd card is in raspberry pi 4.
Raspberry pie boots. No issues with that. No connection to duet

On duet board voltage diodes r on. And status light is dim. Doesn’t blink. Stays dim.

Only thing connected is 24V psu.

Same thing without raspberry pie
