NeoPixel wrong Color

dc42

@heartleander81 have you selected correctly whether you are using RGB or RGBW Neopixels?

Heartleander81

I have in my config.g M150 X1 for RGB neoPixel. That have I use with 3.3, 3.4 Beta 7 and with 3.4.0 .

But with the stabel Version is the issuses.

@heartleander81 can you try addressing just 1 pixel first in each colour and then in all 3. Then expand the test to 10.

I have forget to write I have a Duet 3 6HC with sbc , toolboard v1.1 and PanelDue 5" V3. All Firmware at new Release.

Heartleander81

That I understand correctly.
pixel 1 in white then 3 pixels in white and then 10 in white?

Heartleander81

insane..
Now that I've made a pixel on white, everything works as usual again.
I asked 1 pixel white that was white.
3 pixels were also white, 10 were also white and then 60 were also white.
Hope the error is gone.
I did another sudo apt-get update & upgrade today, maybe I don't know if there was a change accordingly.

After off and on Problem is back. Test 1 Pixel white is this green
3 Pixel 1=Blue 2=withe 3=off

10 Pixel 1=Blue 2=withe 3=green 4=jellow 5=green 6=blue 7=blue 8=Red 9=off 10= off

After a Printjob is all good. After a New start is this not.

@heartleander81
Maybe there are some unwanted signals to the LED-strip at startup? Can you try to clear all LEDs before the white?
Could be in the same line with the configuration.

Heartleander81

@o_lampe how clear i all LED?
M150 P0 S60 ? That use I to make it off.

I was having issues with RGB LED's on my Voron, adding a 1.5K resistor to the Data line at the strip end fixed it.

@rushmere3d dotstar ore neopixel? Neopixel have 1 data line not 2

Rushmere3D

@heartleander81 Neopixels and I'm aware of that maybe didn't explain it right.

Where the 3 wires attach to the strip, disconnect the data and solder a resistor to the wire then the other end to the data connection on the strip. I didn't say anything about 2 data lines?

Heartleander81

@rushmere3d sorry then I misunderstood. But unfortunately I don't have anything like that at home and what surprises me before the update to 3.4 I had no problem with it.

Heartleander81

@dc42 @ I use M150 X1 for RGB NeoPixel

Heartleander81

Issused found. How Can I close ore delet this thread?

@heartleander81

Care to share? What it was and how you fixed it.

You need to mark it as a question, then mark it as solved.

@rushmere3d
I clamped the line for the signals between the ramen and the motor and I suspect that I have generated interference signals.
