Nozzle LEDs flickering if set to white + logo LED effect

[bthubs]

I am currently using a Xol toolhead and wired the LED harness as per their instructions. It uses 1x WS2812B 5050 and 2 WS2812B 3535 (small RGB LED sequins). It works with your typical (static) stealthburner cfg. But since I am using LED effect, there is an issue such that if the logo LED has an LED effect and I set the nozzle LEDs to white, they begin flickering, But if both the nozzle and logo LEDs have an LED effect, they work just fine. I have made a few observations while troubleshooting. I've redid my harness like 5 times as I initially thought there was a loose wire touching something, but each time has been the same effect. Another thing I did notice is that if I set the framerate of the logo LED to something high, the white nozzle LEDs flicker faster, and if I set framerate lower like 2, it flickers slower. This only happens if nozzle LEDs are set to white (ie red=1 green=1 blue=1) . It does not flicker if I have a logo effect and set the nozzle to a single color (R/G/B), but the moment I introduce another color, it flickers. I've also tried virtual_leds as well as putting a 470ohm resistor and it still doesn't work. Both the 5050 LED and 3535 LEDs are GRB color order.

Maybe this is just a hardware issue (ie the small RGB sequins aren't compatible with LED effect?) but it doesn't make sense why nozzle + logo both with LED effect works fine, but nozzle with white and any logo effect doesn't work. I have since changed my cfg to only have white nozzle LEDs while printing, with a static logo LED but I'm hoping a brighter mind can figure this out.

Update (same day): My tests thus far were without any extruding. Now I am having the same issue when extruding while both nozzle and logo have an LED effect. I did recently switch to a LDO Nitehawk 36, perhaps this is the issue? I never tried this LED harness when I had the EBB36 though so I have no point of reference here.

[neopixel sb_leds]
pin: nhk:gpio7
#   The pin connected to the neopixel. This parameter must be provided.
chain_count: 3
#   The number of Neopixel chips that are "daisy chained" to the
#   provided pin. The default is 1 (which indicates only a single
#   Neopixel is connected to the pin).
color_order: GRB
#   Set the pixel order required by the LED hardware. Options are GRB,
#   RGB, GRBW, or RGBW. The default is GRB.
initial_RED: 0
initial_GREEN: 0
initial_BLUE: 0
#   Sets the initial LED color of the Neopixel. Each value should be
#   between 0.0 and 1.0. The WHITE option is only available on RGBW
#   LEDs. The default for each color is 0.#

I have to do some tests to reproduce that and see what's causing it.
I don't use the normal SET_LED anymore on my printer and just do static effects when I want a single color. Maybe this works for you as well.

Do you mind sharing an example of what you mean?

[julianschill]

Check you effect "set_nozzle_leds". That switches the nozzle leds on using an effect. So use that instead of just turning them on in Mainsail.

[bthubs]

I use fluidd and I dont change the colors from the interface, I usually use a macro. Is there anything wrong with my macros?

Either way, I'm suspecting a problem with the nitehawk 36 since the problem gets worse when heating up or extruding. I'll connect the harness directly to the motherboard and get back to you.

[julianschill]

What macro are you using specifically? But there is nothing wrong and it should basically work. Might be a problem with updating the neopixels. Can you please post a klippy.log?

Sorry not sure where to look in this log, its so long... I wasn't getting any errors however. I plugged it into the motherboard (manta m8p). It's showing the same behavior, logo (LED effect - breathing) + nozzle LEDs (static white) = flickering. So it's not the Nitehawk 36. Perhaps it is the 3535 sequins then...?
