      @ccs86 Are you using a Maestro board?

          Yes.

          The lack of floating point unit makes accelerometer usage problematic. I didn't even think there was a build for the Maestro.

            @ccs86 when we are happy with the performance of input shaping on boards that have floating point hardware, we will look at the feasibility of doing a build for the Maestro.

              It is my understanding that accelerometer usage is okay, with the potential issue being in running input shaper. I'd still like to start measuring with the accelerometer for a baseline and for mechanically trying to improve resonance.

              @dc42 Can confirm if that is the case.

                @ccs86 confirmed. Accelerometers should work with the Maestro, but I haven't tested that combination.

                      @dc42 hey so i got now everything working on my board. Also using now the resistor. But now what should i do with the data? How can i now use input shaper? I mean i can view it an hit analyze, but then? Not sure what i should do next.

                        @ducati87 I can confirm that accelerometer support does work on the Maestro. I have update https://duet3d.dozuki.com/Wiki/Accelerometers to include a photo showing the wiring I used. The ribbon cable is 1m long.

                        I also successfully ran an accelerometer using exp.pa21 and exp.pa22 for the CS and INT signals instead of TWD0 and TWCK0.

                          @dc42 can an accelerometer be connected to a 3HC?

                          Owns various duet boards and is the main wiki maintainer for the Teamgloomy LPC/STM32 port of RRF. Assume I'm running whatever the latest beta/stable build is

                            Not yet, but I will probably add support for that at some point.

                              @dc42 ok thanks. Would be helpful as I currently run all my tools off a 3HC and that's where all my wiring goes back to. Its also on the opposite side of my printer to the 6HC.

                                Any ideas on what to try next?

                                I am running:

                                • CAT6 cable, less than 1m length.
                                • CS is run on a conductor with an unused pair (CS on orange, nothing on orange/wht)
                                • 1k resistor on SDO
                                • CS >>> EXP_0
                                • INT >>> EXP_1
                                • M955 P0 C"exp.pa21+exp.pa22"

                                Not found....

                                  @ccs86 try using the temp daughterboard connector instead of the 12864_EXP2 connector. If you have a temperature daughterboard installed, you can connect to the pins on top of it.

                                      do you have evidence that the accelerator board is OK?

                                        The green light comes on, so that's a start. I'm not sure what else I might be able to test with my multimeter.

                                            No, it isn't correct. If the PT100 board was not there, it might be correct. However, the PT100 board does not route TWD0 and TWCK0 straight through, it routes them to the CS2 and CS1 positions on the top connector, so that if you stack another daughterboard on top, it will use TWCK0 and TWD0 instead of CS1 and CS2.
