[ML-General] Weird Smell from Wanhao Duplicator i3 Control Box

[Ryan Coons]

So I bought me a BIQU board, but I'm not sure how the signal wire polarity
works. There isn't a plus-or-minus label, just dotted wire and more-dotted
wire. I read online that there's no signal polarity, but others say that's
false. What did you do?

Cheers,
Ryan Coons
