      I have mine working on my BLV with the duet3. It’s actually easier than it was with the duet2. I can share details and pictures in a bit if you’re interested.

      Yes please πŸ˜‰

        @Nuramori I think there are a few people that would love to know too!

          I just finished the cabling except for the Neopixels. So if you could share your details that would be very helpful πŸ˜‰

            Dumb question, but why neopixel if the duet3 supports Dotstar?

              Because in first interation I'm building a BLV mgn cube as per instructions. How it looks at the end....we will see πŸ˜‰

                @QuintBrand The Neopixel rings on the BLV MGN are much more than just lighting for the unit. The three rings independantly report through color shift and number of leds lit the bed temp, hotend temp and percent completion of current job

                Allowing a quick visual inspection to see if the temps are right and about how much longer on the job.

                not necessary... but SUPER COOL!

                  THX for the reply, I've seen this online and while following the work of Nuramori on his blv. It is indeed really really cool stuff and so I now understand only neopixel can do this because there are round circle ones?

                  I'd like to start with led too, but do hard to figure out what type to use πŸ₯΄β˜ΊοΈ

                    @QuintBrand in theory it should work with any set of LEDs that are individually addressable so you can send commands to each unit to say how many leds and which color. Straight or round is a stylistic choice. So its a bit more complex than standard RGB LEDs which only allow for color and brightness of the entire set.

                      @Nuramori details would be most helpful as this is one of the last implementation items for me as well πŸ™‚

                        Duet 3 supports Neopixel directly as well now.

                          I think the real advantage of the neopixel system by Claus is that it makes connecting them a bit easier and puts no extra strain on the duet. It's a bit easier to connect to as to do a similar thing with the dotstar port you have to chain them while the neopixel system let's you set up a bunch of separate neopixel units. I have one inside my toolchanger/x gantry for parts lightning and then another 5 for status/bed temp/chamber temp/ and print heads. There's even a modified version that someone did that put all the info onto a bunch of cheap OLED screens using the same system.

                            Thanks for the replies; I makes neopixel might be best, but both are supported now anyways. That's nice!

                            Thx

                              In the meantime I'm thingking about the following: set up the Neopixels with the Arduino as shown in the drawing for Duet 2. Connecting the "data in" pin from the Arduino in parallel to the Paneldue "in pin" to sniff the data which is used by the Ardu9ino sketch to get the current status of the job, bed temp and hotend temp. I see the advantage that I don't need to feed the Neopixels via GCODE. The existing rduino sketch is doing that automatically.

                              Would that be an option? Just connected everything, Paneldue is still working, Neopixels are operationak but don't show the current status (which can be the result of the need to adapt the Arduino sketch). So the main question to me is: the Paneldue data connection is serial. What kind of connection is the pin10/utxd0 connector on the Duet 2?

                                Standard async serial with 3.3V signal levels. Do not feed 5V into the Duet URXD pin (or UTXD).

                                  Since it's the same kind of connection the Arduino sketch should work without modifiction. Thanks for the info!

                                  I don't have any TX connection, just reading the data which is send to the Paneldue.

                                    I decided to connect the Neopixel to the Duet 3 Dotstart connector. Will write a script that gets the data and controls the Neopixel via software framework. A first version is already running but I need to finish the printer buid first because it's hard to test without running active print jobs πŸ˜‰

                                      I think i need some more help.

                                      Wired three Neopixel rings (WS2812) to the Dotstar connector:

                                      neopixel-duet3.png

                                      Doesn't matter what I do,only the first ring is working.

                                      For example:

                                      M150 X1
                                      M150 R255 P128 S20
                                      

                                      Each ring has 16 LED's. So I would assume that the first 4 LED's of ring two are lighting up.

                                      Even if I do a

                                      M150 X1
                                      M150 R255 P128 S48
                                      

                                      only the first ring is working.

                                      Am I'm doing it totally wrong?

                                        @MartinNYHC So in both of these cases, all of the LEDs on the first ring and none of the LEDs on the second ring are lighting?

                                        This is very silly, but in your drawing the 5V and GND are flipped on rings two and three relative to one... That's not the case in the actual rings, right?

                                          Yes, exactly. Doens't matter what I do, only the first ring is working.

                                          And the 5V GND flip is only an on the drawing πŸ˜‰

                                            @MartinNYHC I only asked because if it was me there would be an at least 50% chance that I wired them backwards. πŸ˜›

                                            Have you tried swapping which physical ring is first in the series to make sure it's not a hardware problem with the Neopixels?
