Coil A

Coil B

Could it be that only spool A is damaged?

I have filled in my Duet replacement request, thanks!

@dc42

Following the diagram I have attached the winding A and B. In both gives me continuity without resistance, ie short circuit. And endless resistance between them.

I can do some more test, if you want. It seems that the duet works correctly except for the E0 output.

If just that, from 0.7A, I have asked for another equal ...

@t3p3tony
I thought about doing it, but the engine got very hot and smelled like burnt, and I did not dare to try it for fear of burning another channel.

Thank you, I appreciate it very much.

In the driver microchip

Hello, my duet is a week old, connect an engine (25mm brand pancake bondtech) which did not work, it vibrated a little but it did not turn, one of the times I connected it started to heat up, until they started to jump sparks the duet (my tears also leapt), I think it was the engine's fault despite being new ... I have again asked for another similar one, I'm worried if it happens again ...
Thank you very much for your interest.

Ahhhhh Ok!!

Tahnks!!

Thank you very much for your reply. I have made all the changes he suggested, but the E0 continues without disappearing ... And now the E1 does not appear.
