Hello Duet3D Forum,

i have buy 2 Duet 3 Expansion 1XD. I have connected one Expansion 1XD on my Duet 3 Mainboard 6HC.
The 5V LED/VIN LED lights up. and the STATUS LED is flashing. I have change the CAN Address to 121.

I Connect the second Expansion 1XD but the 5V LED does not light up. The same with the STATUS LED.
Only the VIN LED lights up

I checked the connections without success.

What can i Do?

@phaedrux I did that, but didn't change anything

@phaedrux no

Only Vin, And 5V

Thanks for the Great Support

The 5V LED is now lightning. But the Status LED is not Lightning or flashing

What can i Do?

@dc42 i have never Seen the light in the 5V LED.

I have only connectet VIN and only this LED ist Lightning
I have only VIN and CAN connectet, only VIN LED ist lightning
My Last step i Connectet The Motor in B122. ( VIN,CAN, Motor ist connectet), only VIN LED ist Lightning.
Bevor the next Connection, i make the Power Off.

I asked the Store to replace the 1XD after LED's did not light Up as described. He referred me to this forum for guarantee approval. How can we proceed with this?

1. 1XD Name for Topic B121 (with CAN Address 121)
2. 1XD Name for Topic B122 (broken and default CAN Address)
   @dc42
   The first 1XD (B121) have all Functions, The Motor is Driving.
   I have Connect B122 on VIN 24V and only the VIN LED is lightning

The boards are attached with spacers. And there is nothing conductive on the back. The wall is made of plexiglass

@Macgyver
I have B121 disconecctet from VIN and on B122 is Only VIN lightning. I have switch the Cable from B121 to B122. This change nothing.
