      Hello world!

      I finished rebuilding my Geeetech A20M (kind of an Ender3 with dual color) using a Duet Maestro. The printer is supposed to allow printing with 4 colors (I am using two E3D Cyclops for that).

      While the onboard stepper drivers work very nicely, I am facing an issue with the official driver expansion board (or anything that I am overlooking here):
      The motors that are driven by the expansion board are very loud (when moving and when at rest). Exchanging motors (I have a couple of spares), does not help. Exchanging wires (I have spares...), does not help. I also have a second expansion board - switching to it does not help. Switching to onboard drivers makes the motors quiet.
      There is a bit of a difference between E2 and E3 though, E2 is even louder (E3 may be considered okay-ish). Nevertheless, by inserting E3 into E2, the E2 socket is as quiet as E3. That means, it does not seem like an issue with the board?

      Lets talk about firmware and config. I am using SpreadCycle for all drivers and I added the "T3" part to the expansion board to make sure that there is no trouble with the timing.

      Here is my config.g file.

      I will post the system diagnostics when I am back home. I am using "RepRapFirmware for Duet 2 Maestro version 2.03 running on Duet Maestro 1.0".

      With this preanalysis, I would assume that my Maestro might have an issue - or my config is wrong - or both of my driver expansions are weird. So now I am looking for help - as I am running out of options. I was thinking of using some stepsticks that I have and try these with the expansion header. Something that I might try is to attach an oscilloscope to the STEP/DIR/EN pins and check if the signals look fine. What kind of bandwidth would the osci require to do so reliably (I wanted to buy one anyway)?

      Any ideas?

      Thank you in advance!

        @Wurstkarton The T3 should not be required for the Maestro expansion board because they are controlled over UART so should be the same as the on board 2224s from that perspective. Try without that.

        Can you also try running them all without D2 and comparing.

          Thanks for the response. Of course I already tried that too. Initially, I used that setting. But that does not change anything. Also the V parameter is not effective, because I am using D2.

          For me the behavior of the noise is somehow weird: I tell the stepper to move a millimeter and when it comes to a stop, the noise is kind of changing - loud for a while, then silent, might become loud again. I dont know...

            @Wurstkarton what is it like without D2.

            Stand still noise can be improved with standstill current reduction (which you have configured but you can set it lower for extruders).

              Yes. I am using a value of 50%, but that does not change much (also going lower). I also know the F parameter, but that does not improve the noise. It even makes it worse changing from the default value of 3.
              The main question is: why do the expansion drivers perform worse than the onboard devices? Or is it something else?

                If you have configured them in exactly the same way (in particular, the M569 parameters and motor current), then the expansion drivers should behave exactly the same as the on-board drivers, unless there is a hardware or firmware issue that we don't know about.

                  Okay. This is an answer I can work with. I think I might try to get my hands on another Maestro then. This is the only thing I can think of...

                  BTW: otherwise I am very pleased with it! Works like a champ! Not that anybody gets the wrong impression here...

                    Yes. I am using a value of 50%, but that does not change much (also going lower). I also know the F parameter, but that does not improve the noise. It even makes it worse changing from the default value of 3.
                    The main question is: why do the expansion drivers perform worse than the onboard devices? Or is it something else?

                    If you have configured them in exactly the same way (in particular, the M569 parameters and motor current), then the expansion drivers should behave exactly the same as the on-board drivers, unless there is a hardware or firmware issue that we don't know about.

                    Okay. This is an answer I can work with. I think I might try to get my hands on another Maestro then. This is the only thing I can think of...

                    BTW: otherwise I am very pleased with it! Works like a champ! Not that anybody gets the wrong impression here...

                    I think it unlikely that a hardware fault would cause a different behaviour. The only reasons I can think of for different behaviour is if the daughter board was manufactured incorrectly, or a firmware bug.

                    Can you be more precise about the differences between an extruder connected to E0 or E1 on the main board, and the same extruder connected to one of the expansion board outputs, using exactly the same M569 settings (adjusted to account for the driver number) and M906 settings in either case?

                      Interesting answer. I ordered both of these expansion boards(well I got the second as a replacement for the first, although it behaves as the first..., came to a similar conclusion you did) from the official duet3d page. I also ordered another maestro to rule this out from the equation. Will arrive next week.

                      Currently I am on vacation. I'll be back next weekend and can provide the information at that time.

                      [Another edit]: differences between internal and external is mainly noise. It behaves much more "rough" using the expansion board (and also there is a lot of noise when the motors are only in holding position. No noise at all with the internals). I can make a recording of the sound when I am back.

                        I started working on my printer again during the weekend. After installing a replacement Maestro, I can confirm that this is not the issue. It rather looks like an issue with the firmware or a concept issue with the driver expansion.

                        • can't be a faulty maestro (I tried two of them with same behavior)
                        • can't be a faulty driver expansion (I tried two of them with same behavior)
                        • can't be a faulty cable (I tried several of them with same behavior)
                        • can't be a faulty motor (I tried several of them with same behavior)

                        I will provide my config.g and M122 output this evening (as I am currently working on making a silicone mold for the E3D Cyclops+, I was short on time...).
                        If I have the time, I might take a look at the expansion schematic. Maybe I can see something by comparing it to the onboard drivers.
