Duet Wifi went Bang on first startup

[mmoram]

Thats the frustrating thing I did double/triple check the wiring, this is the problem, i cant see where i went wrong, everything looked correct

If you post some photos of your wiring/setup, might be able to spot something.

A possible cause is +24v getting into the heaterblock, and the heaterblock touching the IR sensor (which is on the 3.3v rail).

As suggested post some photos. It is likely that there is a wiring error OR perhaps a short.

Anything on the underside of the board that could have shorted something?

I'm sorry to hear that your board has failed. Please post a photo of the damage so that I can identify which chip has failed.

@dc42 Yes not a problem, ill send over some photos this afternoon after i finish work, Thankyou

@fcwilt Hi There
Here are the photos, hopefully you will be able to see if ive wired it wrong, but i think everything is correct. The board is also on 10mmplastic standoff son that nothing can short out the underneath.

@dc42 Hi There

Thanks. I don't think that failure was caused by your wiring. Please ask for your Duet to be replaced under warranty, referencing this thread. See https://www.duet3d.com/warranty.
