Not Starting at the 1st Pixel

[CraigB]

I have 3 trees on each side of the driveway. On the AlphaPix16 that I am using I have Driveway Left Tree 1 (Univ 19) and Driveway Left Tree 2 (Univ 20) on the same output (SPI 7) and Driveway Left Tree 3 (Univ 21) on SPI 8. The AlphaPix16 can do 2 universes on the same output. Same setup for the right side trees (Univ 22-23 to SPI 11 and Univ 24 to SPI 12). Trees 1 and 3 work as should. Trees 2 start at the 21st pixel ignoring the first 20. They are all set up the same way. I have tried switching the different trees and renumbering them, but the same keeps happening. I would appreciate any ideas that anyone may have.

I have included the xlights_rgbeffects, xlights_networks, and the AlphaPix16 settings.

Looks like according to your setup Left Tree 2 should start on channel 451 and then run into Universe 20 on its own.  You have the element setup in xlights to go straight to universe 20 thus skipping over the first set of channels in the controller.  What I would try is change your xlights setup to start left tree 2 on channel 451 and drop an effect  on it and see what you get.

I started Left Tree 2 on 451 following Left Left Tree 1 as suggested. When testing Left Tree 1, all 50 work and also the first 20 on Left Tree 2. When testing Left Tree 2, it starts at pixel 21.

I can put them on separate outputs, I wanted to used them together so I would only have to run one cable to both, but I can run two cables, one for each.

The problem is you told the AlphaPix that there are 300 pixels starting at universe 19 but in xLights you defined universe 19 as 150 pixels and then started universe 20 as 150 pixels.  You should change xLights to have 510 channels for universe 19 and then it will properly roll over into universe 20.

When I started Left Tree 2 as suggested, I also changed the AlphaPix Universe 19 to 510 to roll over.

I originally had them setup one after the other and saw this problem when testing. I then assigned each their own Universe thinking this would take care of the problem. It didn't. The only way I was able to not have this happen so far is to have each one on its own output channel on the AlphaPix.

[Gilrock]

You need to do what I said.  Change universe 19 to 510 in xLights not the AlphaPix.  The AlphaPix does not even have a spot to enter number of channels it has number of pixels where you have 300 so that's already defining 900 channels.

[CraigB]

Sorry, I didn't mean in the AlphaPix. I did change Universe 19 in xLights to 510.

Ok how are you testing?  I like to just create a new sequence selecting 3 green buttons in a row and then drop an effect on a model, click output to lights and see if it's working.

[CraigB]

I am using the Test in xLights for the models.

[Gilrock]

Guess I gotta ask.  You did check the Output to Lights checkbox?

[CraigB]

Don't blame you for asking, but yes. I had Left Tree 1, Left Tree 2 and Left Tree 3 hooked up for testing. That is when I saw the problem. The hooked up Right Tree 1, Right Tree 2 and Right Tree 3. Same thing. The left and right trees are layed out the same.
