Duet 3 Expansion looses connection while printing

Do you have jumpers installed as per the highlighted image below?
The power cables just happen to be in the wrong place.

@jay_s_uk
Yes, i have the jumper like your photo -
Are you able to connect to DWC?
If so, please go to the system tab and upload this zip file, as is.

Does it successfully update your firmware?

@Phaedrux I tried to update with this firmware but the problem persist...
-
Did the firmware update complete successfully?
-
@Phaedrux yes , and the board has rebooted

RRF 3.2 Beta 3 is coming soon and may have a fix for this. Look out for that in the coming days.

One situation in which I have seen this happen on my bench setup is a combination of a high-power bed heater driven directly from the Duet 3, long (~1m) and relatively thin wires between the Duet 3 and the PSU, and separate wires from the PSU to the expansion board. Daisy-chaining the power from the Duet to the expansion board solved it in my case. Shorter and/or thicker wires between the Duet and the PSU would probably have fixed it too.
