Please stop this kind of topics title.
First i'm not the only one who can answer to questions
And with this kind of topic title, next one who need an answer to this question cant find it by using the search feature of the forum.

However, here is my video on how i connect my Nema23 : Nema23 on CNC Shield

Take a look at this video as well. You'll see how the guy wires the drivers, notably the power line. That was something that wasn't clear to me from Topsie's video. With this, you should be good.

And yes, Topsie isn't a customer service rep, lol. There are many many helpful users on this forum as well as a newly minted search feature. ;-)

Sorry, did not mean to cause any trouble.  Thanks for the responses

No worries  ;-)
