      @ctilley79 the new commands for configuring and controlling LED strips are implemented in the 3.5.0-beta.3+ binaries that I posted. They have been tested on Duet 3 Mini and 6HC.

      @Exerqtor please post the M950 and M150 commands you used.

        Hello, @ctilley79,

        I generally have these issues when there is a problem with the wiring or the connectors. Manual extruding via DWC works fine, but then the motor needs higher currents, it move backwards because the wires only let through so much current.

        I would check every wiring the in particular the soldering joints and connectors. This solves this particular problem for me every time.

          That's weird, since i'm quiiiite sure i'm using the right command set (for a Duet3 Mini).

          I TRY to send M950 E0 C"DO" T2, but i get the error mentioned above.

          The M150's have been changed to this (for example):

          M150 E0 R150 U150 B150 W150 S1 F1
          M150 E0 R150 U150 B150 W150 S2 F0

            @Exerqtor Is "DO" a valid pin name on the mini? I had a quick look and couldn't find any pins with that name. Is this for the neopixels in a display attached via the exp headers?

              @Exerqtor Are you sure DO is right and not D0?

                @oliof I copied it from the docs since I was unsure about the exact same thing 😆 So unless it's written wrong there as well it should be correct.

                  @Exerqtor Which docs? I've just checked the source and there is no pin called either D0 or DO as far as I can tell. What pin are you trying to drive the neopixels from?

                    The only pin that supports it on a Duet 3 Mini, which from what I can see lacks a proper explanation on what the "DO" pin is actually called. "ctrl+f" search for DO here and look at the 14th entry. Thats the only mention of it (that i'm able to find) in all the docs / schematics.

                    It's also just called "DO" in the schematics:

                      @Exerqtor the dedicated LED port is known as "led" in the firmware. This needs to be added to the documentation.

                            Does the M150 P parameter to work for you on this firmware build? I'm also using RGBW neopixels. The P parameter does nothing right now.

                              I don't use the P parameter, only the R/G/B/W component "amount", it should yeld the same result although you would have to play around with the values to get the same effect.

                                @ctilley79 you are correct, the P parameter doesn't work for Neopixels. I will correct this before we release beta4.

                                  May I know how to define M950 for Duet2Wifi? It can use M150 directly before, however it is failed and need definition first now. But not pin name found...
