I’m building a KR Sabers Erasmios from The Labor Armory’s DIY Kit. (Hilt + ECO-CC Chassis DIY Install Kit). Is this the right way to set up the Config for everything included with this kit? It has a 12 pixel accent and the crystal chamber pixel.
From a glance at the saber it seems to be a thin neck. Pretty cool design using a ring and a mini pcb at the top of the main chassis! I’m assuming you are using the fixed chassis version as you have no LED screen.
I’m scanning this video:
In your config and diagram you have 2 data lines running directly to the hilt side pcb/ blade connector, but the micro pcb that sits inside the top led ring on the chassis has only one data ring. You can’t actually do this specific set up.
Also I think that it comes with a the ECO version of the hilt side blade connector pcb, which has one data line.
So the accents are fine but the blade PCB needs only one data line, which will then hit the pcb in the neck, which contacts the chassis pcb and then the board.

Agreed with @LyleStyle on the thin neck connector. You will only have 3 wires going to that ECO NPXL V4 so you won’t be treating it as an “illuminated PCB” in the configurator. While it is a lit PCB, it will light just like the first 30 pixels of the blade would and you don’t need a separate data line to do that. So with no blade in, you’ll still get light coming from the emitter as expected. Your pixel ring should likely be set for 20, but verify your in hand hardware. Also, make sure you change the 144 for the blade length to the true blade length when you finish building it.
Keep in mind your pixel ring and crystal chamber pixel typically already have an in-line resistor so you probably don’t need a separate one as shown - just verify they have a tiny resistor, but all those I’ve seen have them. The diagram shows them separately because Proffie V3.9 has it built into Data 1, but not the other data lines.
And your bladeconfig would be like this (except 144 changed to actual) :
BladeConfig blades[] = {
{ 0, WS281XBladePtr<144, bladePin, Color8::GRB, PowerPINS<bladePowerPin2, bladePowerPin3> >(),
WS281XBladePtr<20, blade2Pin, Color8::GRB, PowerPINS<bladePowerPin4, bladePowerPin5> >(),
WS281XBladePtr<1, blade3Pin, Color8::GRB, PowerPINS<bladePowerPin1> >()
, CONFIGARRAY(presets) },
};

Removable chassis, you are definitely correct about the data lines. After tracing it out between the different connections there is only one available data line that transfers to the hilt side blade PCB.
Thank you for your quick reply!
Pixel ring is 20 (not 12, my mistake) Also no resisters on the pixel ring or crystal chamber but they shipped with resisters. The emitter PCB did had an in-line resistor on the back.
Gotcha. So you’ll want to use them in line if not already there. The one on the NPXL won’t really be needed in your case since you’ll want to wire to Data 1 and that has one. In any case sounds like you should be in good shape. Enjoy your build!
I actually did my own custom chassis for this hilt.

I can also confirm the configuration @jedimaster is what I’ve used in my build.
