Issues with LED matrix set up

[_Samwise_]

Hi all, I have an P50 LED matrix that has 3 inputs that a 800 pixel serpentine runs (2m x 1m arranged vertically) that I've assigned to 1-3 of my falcon controller but I'm really struggling to get them to behave together as a single panel. I've tried using 40 strings and 60 nodes but that causes the auto-layout ports to overflow. The effects are appearing but they're doubled from the center or in the wrong orientation. The effect should be a single yellow spiral.

Thanks in advance for any help

Let's review the settings.
It certainly looks like the lights are connected up/down, so vertical is correct.
Because you have 3 controller ports, 3 strings is correct.
20x40 = 800, so that number of nodes/string is correct.
Where I think it might be wrong is the number of strands/string. There are only 20 strands, with 40 nodes/strand (the strand is the vertical direction on a vertical matrix).

Where I am not sure is whether it is actually serpentine, or is not. Some of the new curtains use addressed pixels and it all starts at the top. So if it doesn't work (it looks like some comes from the top, and some from the bottom), tick "don't zig zag" and try again.

Be sure to re-render between these changes. (If the output count changes be sure to reupload the controller also.)

As a good test - RGBW vertical bars across the display, then RGBW horizontal bars down the display. This will definitely help identify the serpentine issues and things like that.

There's a second thread about this - not uploading the controller certainly seems to be part of the issue... if that doesn't get fixed none of the other experiments are valid, really.
