      Hi there- I have a strange error:
      I connected an Accelerometer.
      As soon as I post a M956 command the Board "crashes" (nothing happens and after a few seconds the board reboots). I can also find the file created in the accelerometer folder but it is empty...?
      Any suggestions what I am doing wrong?

      greetings kuhni

        Just tried the other duet board I own (a cartesian printer) - there a file is created with the message

        Sample,X,Y,Z
        Failed to collect data from accelerometer

        very strange...?

          another strange behavior:
          I can adress the Accelerometer with the command:

          M955 P0 I46 C"spi.cs4+spi.cs3"

          but if I then want to change something and post the code again (e.g. to change the Frequency)

          M955 P0 I46 C"spi.cs4+spi.cs3" Q500000

          I get the error

          M955: Accelerometer not found on specified port

          is this normal? Do you have to reset the Board to "re-activate" the possibility to declare an M955 command?

            @kuhnikuehnast I'm not sure why that is happening, however you don't need to repeat the M955 C parameter or I parameter when you just want to change the data collection parameters.

            If the board reboots unexpectedly, please run M122 as soon as DWC has reconnected, and post the output here.

                @kuhnikuehnast I suspect that there may be a problem with the INT connection from the accelerometer to the Duet spi.cs3 pin.

                  @dc42 so what should I do? When i connect the same board (and cable) to the other board it "works" - as mentioned above... "failed to collect data"

                    I now tried something else:

                    • I switched the CS and INT1- Pin (so I declared the M955 to:
                      M955 P0 I46 C"spi.cs3+spi.cs4"
                      instead of
                      M955 P0 I46 C"spi.cs4+spi.cs3"

                    but as soon as I ran the code:
                    M956 P0 S1000 A0

                    I got another crash. In this time this was the M122:

                    Do you see something different? So is my Duet broken? Or how could I solve this problem?

                    Hope you can help me!

                      @kuhnikuehnast it could be that writing to the SD card is taking too long. You could try a new SD card. Alternatively, reduce the number of samples you are collecting, for example to 500.

                          @dc42 btw what is the biggest size possible for the SD-Card? So I'll get to grab a new one...

                          sorry, got it already- so I'm out now heading to a store to get a SanDisk Extreme Pro 32 GB mircoSD 😄 cross fingers for me that this will solve the problem!

                            I think I solved the problem:

                            • it wasn't the SD-card- but as I changed the cable and re-crimped an USB-3-cable everything now seems to work! 🙂

                            yihaaa 🙂
