@bearer This is what I see when looking at the U3 chip:
Not sure if that's damage in that South-east ring, but could be?

Looks like damage to me. You may be able to pin-probe, with a steady hand, and discern something from this:

the parts orientation dot should be in the same corner but doesn't look quite right no.
if you can't replace it and its not within the warranty period you can wire a dc/dc converter between Vin and the ext 5v header (asuming no other damage)

@dc42 -- I've seen from other posts that U3 failures are within warranty criteria. What do I need to do to start the warranty service process?

@CoolioX Unfortunately, the failure of your board would not be covered by the warranty. As you stated:
Earlier today, the wire from the heater fan was run over and shorted out the printer.
This was the direct cause of the board failure. From https://www.duet3d.com/warranty

..from what I read there is nothing preventing you to do do that right now; just connect 12v/24v/Vin + USB and print on..
