Having problems with my P2

Hi all, Im stumped.

This is my 3rd P2 that I have for my matrix.

Matrix is 26x50 individually controlled (30IC/30led per meter). The first 13 lines are Output 1 (650px), the 2nd 13 lines are Output 2 (650px).



I have power injection from every 2nd strip. Strips 1-13 from PowerSupply1, Strips 14-26 from PowerSupply2.

From the moment I turned them on all but 3 were working, strips 11-13.

I intially resoldered all the joins...nothing
Rewired the connectors that I have from power injection points to power supply
Triple-checked P2 config



Data does appear to be going to the strip?


Power still appears to be going to strips as well as tested with multimeter.

We (alec spent time helping me out, thanks alec!!) tried going straight from #10 strip to #13 (have to skip 2 due to direction of strips), nothing. Tried going straight from #9 to #12, nothing. The last working strip is #10.

#11-13 have been out the whole time when part of the matrix.

However if taken away from the matrix and plugged directly into a P2 output, #12 & #13 work. Only strip #11 doesnt.

As this strip is each led has IC I tried at different sections along strip #11, still nothing.

Unfortunately I only have 1 spare bit left JUST long enough to replace it so decided to try that. That works directly from P2 output, but once again, once added to the matrix doesnt work.

I have swapped over the 2 x P2 data cables as well, put Output1 wiring into Output2, the same.

Pixels 501-650 will not work within the matrix.

Problem could possibly be #10 strip?

Tomorrow I will try and go from 9-12-13-10 just to see if it works.

An ideas anyone?

Update edit: I just hooked up PowerSupply1 that has P2 and power injection to #1-13. I had the new bit of strip + 12 & 13 hooked up and all 3 worked at the same time, first time Ive seen it. Thats a start, so will try the above 9-12-13-10 tmrw.

k, now Im having software issues.

This is how I have my effects config setup in P2



String config is:



Unfortunately there are 2 areas where images etc dont come out right due to the universe ending in the middle of the 4th row.

That 4th row (#01D) starts in the middle, goes to the end, then starts at the beginning to the middle.

The same thing happens again of course at the end of the 5th universe (#05D).

This is obviously due to the reverse setup?

Is there a way around this?

Doesnt sound to be away around this unfortunately :(

I have had to remove 2 x 50px lengths which now makes the matrix 24x50.

I could have swapped it out with a P12R but that has been completely setup for the Megatree so tree would need wiring setup for P2 instead, plus I would have to change over the jumpers for each controller and I may not have room on the tree for the star on top so.......

I removed the 2 strips and did some re-wiring. All going really well now :)

Although you will be missing two strips, it still looks like a pretty cool matrix

I'm also about to build a 136x12 matrix with the 30LED/M individually controlled strip, via 2 x P2's too, so I guess I'm about to find out if I'll have the same problem! I'm also hoping I can run the full 4 universes per output.

I just won't be doing any effects on the P2, as my own software will map the matrix out accordingly.
