Now, because the first part of the video is not there, I am not sure if you have the spinner approximately upside down or wound the wire the opposite way or have the video flipped. Which way was up? (It doesn't line up with the mounting fasteners, which could get confusing later.)
This is...
The simplest explanation still is that it's off a bit somewhere. Extract this zip, put your controller info into the layout, upload output, render, and output to lights... take some photos of the different sections of the sequence. Maybe we can find it.

When you say "If i alter the nodes to suit say the spinners , then the rings are out of sync" what change did you have to make? Maybe the detail there will be a clue.
Surely there is some fiddly difference with the wire path vs the model... I would check the start+end+string joints carefully...
Tell me about the "commercial DMX adapter". Was it sold in a pair (on Amazon)? Some of those are nonstandard and only work as a pair.

But the rest I tried (often with a bit of cord on them) didn't.
But am suspicious that you can have more...
Let's take off the table anything you could do with expensive load sharing PSUs. Then yes, 2 is the limit for attatching to the Baldrick 8. As circled.
In rounded-off numbers, an LRS-350-12 puts out 30A and the board takes 4x7.5=30A. Nicely balanced. 7.5A will run a lot of pixels. And 7.5A...
What kind of pixels and what voltage?
1. Splitting a board into multiple smaller PSUs is pretty common. The number is limited by the comtroller board, which will have terminals for groups of (generally) 4 or 8. The small PSUs are popular because they're cheap, but you can use whatever. Use...
Agree. If it happened to you, it's a thing.
A pixel that flakes out after a while, or after the voltage drops due to the other pixels being lit, takes out the part of the string that follows. It happens, different details for some kinds of pixels than others.
One recommendation... if you...
Well, it is not "xlights" or the PSU if everything else is working.
I will start with things that are less likely to help but easier to check. (Generally, not sure how thorough you mean by "working", if that means "lighting up" or exactly right in a complex case.) And apologies if you already...
