      I'd like to configure 5 neopixel strips with 8 LED's each on a Duet2 (MotionSystem&Toolchanger) running RRF3.5.3.
      When i config more than 2 strips, a warning appears "Error in start-up file macro line 143: in file macro line 143: M950: parameter 'E' too high"
      config.g

        @cosmowave why not wire then as a single strip of 40 LEDs?

          @dc42 It's a nicer wiring for me to do it with 5 individual cables...
          Is it not possible to use 5 strips like mentioned in the docs?

            @cosmowave Check the 'limits' section of the Object Model, there should be an entry for how many LED strips are supported. On my Mini 5+ on 3.6.0-beta.1 it is 5, not sure what it is on a Duet 2:

            M115

            echo limits.ledStrips
            5

              @droftarts Thanks for the info.
              My system reports taht only 2 strips are supported...

              But then the documentation is wrong:
              In RRF3.5: "Multiple LED strips are supported, up to 5 in a system (mainboard + expansion boards)."

              I have updated my Duetm to 3.5 for the reason to use 5 strips.
              Unfortunately, before i have installed my 5 strips system on my printer, i have it tested only with 2 strips. With 2 everything was working perfect.

              I have to think about if i will rewire everything... 😕

                @cosmowave Thanks, I've updated the documentation here: https://docs.duet3d.com/en/User_manual/Connecting_hardware/IO_Neopixel_DotStar#neopixel-leds

                Multiple LED strips are supported:

                • Duet 3: up to 5 in a system (mainboard + expansion boards)
                • Duet 2 WiFi/Ethernet: up to 2 LED strips, limited by RAM

                It's possible that @dc42 might be able to increase the number of LED strips supported in the next release, particularly if you're only using a small number of LEDs on each strip. But it will depend how much free RAM you have on the Duet, as space is rather limited on Duet 2.
