@mficken Sorry no-one got back to you; the forum has been very busy lately, like people have got time on their hands or something!
It looks like the 3.3V regulator U3 has failed (dim LED, things getting hot). I'm happy to approve a warranty replacement, assuming the board is less than 6 months old.
Please contact the place you bought it from, and follow their warranty process. They will ask for evidence, so please supply them with a link to this forum thread. If you bought it direct from us, our warranty terms are here, and a link to the warranty form is at the bottom of the page: https://www.duet3d.com/warranty
