RE: Another Maestro board burned by BLTouch
Thanks for the quick response! The ebay board was from an individual (not random international seller) and looks 100% identical to the one that shipped with my Quad so hopefully it is legitimate!
@Danal, since we are both in the US, are you interested in attempting a U3 swap on this board? If not, I'll send it back to Duet.

Another Maestro board burned by BLTouch
I was excited to add a BLTouch to my M3D Crane 3D Quad (uses Duet 2 Maestro) printer to address some first layer adhesion issues. I ordered the V3 BLTouch from Antclabs on Amazon and installed it following the diagram at the top of this post which for some reason I found before the wiki section. I triple checked the wiring and it matched the sketch and made sense per the BLTouch datasheet. Anyway, a minute or two after powering up the printer, I let the smoke out of U3.
After doing more digging I found the wiki linked above and hilarious how to destroy your duet 2 wiki.
I ended up finding a replacement board on eBay and installed it per the wiki and all is good. Since @dc42 showed interest in tracking the U3 failures in a few threads, I figured I'd post my experience.

I'm happy to send the board back if it helps future design efforts or its something you can refurb.Matt
