      I've had a problem with the NeoPixels since the 3.4.0 stable update.
      For example if I
      M150 R255 U255 B235 P128 S60
      enter then I have a colorful LED bar, but it should be white.
      No matter which RGB I use, there is no pure color.
      With 3.4 Beta 8 was all good and work correct.

      Have anyone a tip for me?

        From my understanding, you have to add F0 or F1 to make the command complete.

        What do you mean with colorful? Is it random color?
        Did you set M150 X? Q??? before you send the line?

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

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

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

                    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.

                        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.

                            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.

                                @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?

                                  @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.

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

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

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