M955 Accelerometer not found on specified port
-
Duet 3
RepRapFirmware version: 3.4.4
Duet Web Control v3
Printer architecture: CartesianProblem: I am trying to connect the LIS3DH accelerometer to the Duet board to utilize the input shaping functionality, but after wiring the LIS3DH to the Duet board, the Duet board does not recognize any accelerometer being connected. I made sure to follow the wiring schematics in the documentation. An error pops up regarding the M955 command, saying that an accelerometer could not be found on the specified port.
Below is the config.g code

Thank you for your time

How long is the cabling? People have had best luck using a USB3 cable.
-
The length of the cables that were used in the picture were around 5 inches long. I'll try the USB3 cable approach and see how that goes.

@BryanPlummer I would expect it to work with cables that short. I will study your wiring photos.
-
@BryanPlummer it's a little hard to tell from your photo, but I think you have the red and white wires plugged into the wrong pins on the Duet. They should go to pins 8 and 6 respectively, but I think you have connected them to pins 10 and 8.
