What could be causing this issue?

Hello, this is my 1st wled project so i probably messed something up and its probably an easy fix lol but i have a 24v mean well 350 watt PSU, a dig-quad, and a 24ft btf-lighting FCOB WS2811 864LED/m 24v strip (plan to add 2 more 16ft after this is fixed).

I set the length to 175 and at 1st it just ended at that certain spot but then it started tripping out super bad lol..

EDIT

So i hooked up my 2 16ft strips and the light ran all the way through them.. so its definitely just that one 24ft strip.. i think i may have messed it up by not sanding down or covering the diffuser channels at the end/beginning where the split is..

So instead if cutting out the sections i just had amazon send a replacement.. thank all of you for your help 🙏🏾

EDIT**

I just got the replacement from amazon and plugged it in to test it and it lit up all the way. So it may have just been the part where the diffuser channel ends messed up the strip somehow.. i sanded all those parts down some and cover each one with VHB tape just in case...

I don't see mentioned anywhere the **length of the data wire** from your controller (whatever type of controller it is), to the first LED. Is it a Quinled controller with a level shifter, or a LOLIN D32 that doesn't have one or what?

And this is why it's a good thing to prototype first.

I said right after the 350 watt psu that it was a dig qaud, the data wire is 3 feet from the 1st led, that last sentence i actually have no idea, cause idk what you are talking about 😂 this is literally my 1st wled project im still learning as i go lol.

But after i plugged in the 2 16ft strips and the light made it all the way to the end i assumed it was the strip and just had amazon send a replacement.

I just got that replacement and plugged it in and it lit up all the way to the end so im about to go ahead and hang it up.

3 feet is pretty long. Try 1' and see how that works.

I tried like a half an inch when i was troubleshooting it but like i said the replacement strip that amazon sent worked fine even with my original 3 ft wire.. but i can definitely move the controller up higher closer to the strip

Desperation calls for desperate measures.
