Is my Duet 3 Expansion 1XD broken?
-
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 upI checked the connections without success.
What can i Do?

@speedy86 it sounds like either the 5V regulator has failed, or something is shorting out the 5V power rail, or the VIN voltage is insufficient (12V is only just enough for the 5V regulator on the 1XD). Does the red 5V LED still not light up if you have only VIN power and nothing else connected to the 1XD? Also check that nothing conductive underneath the 1XD could be touching the connector pins and shorting them out.

If I understand correctly you have 2 expansion cards, call them 1 and 2. 1 seems to work properly by itself but 2 does not work with it.
Could you consider using just 2 without 1 and see if you get voltage on the 5V rail? If this works that will tell you the board itself is good and the input voltage is too low to support 2 add-on cards.

- 1XD Name for Topic B121 (with CAN Address 121)
- 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. -
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?

@speedy86 you didn't reply fully to my earlier question:
Does the red 5V LED still not light up if you have only VIN power and nothing else connected to the 1XD?

@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. -

Does it light at all at power on?

@phaedrux no
Only Vin, And 5V
-
If nothing is plugged in other than power and the status does not flash at all then they can try jumpering the CAN_RESET and power cycling.
-
@phaedrux I did that, but didn't change anything

Hmm, that is unfortunate. I think we'll have to replace it under warranty once more.
