Fried 6R8 inductor and Z1284PI - why? Wiring problems

dc42

I am sorry to hear of your misfortune. The Z1284 is the 5V buck regulator ship, and the 6R8 inductor is the output inductor connected to that chip.

We'd like to get the board returned to us for analysis. Which country are you in? We'll also provide you with a replacement under warranty. Please get in touch with your supplier for this.

I'm from Germany and got the board directly from you guys. I'll gladly send it back to you. Thanks!

... no schematic available ...

We do intend to publish the schematic, but we want to move our hardware design files to the Duet3D repository first. In the meantime, here is the Duet 3 MB6HC v1.0 schematic. The V0.6 board is almost the same.

I switched one of the two endstops to blk GND and red 5V

You placed a dead short across the 5V rail.

And for microswitches, you should be using the in.io and ground, not 5v and ground

i know, you've said before it'll be released in due time, wasn't my intention to "complain". interesting to have a peek

Correct. But we expect Duet 3 to survive such a short, just as Duet 2 does.

Also correct.

Thanks, For that Endstop Hint.
It would be great to get my Wiring and G-Code Setup looked over before i'll turn it on the first Time, because i've a exotic Conductive Z Endstop where i can find only duet 2 informations for.
My genuine duet 3 6HC is directly from duet too.
Thanks for that great Service.

Cheers,
