Hi, I have the Duet 3 6HC board, and I'm wondering about Uart communication between the Duet board and any other peripheral and the voltage that Uart is tolerant to. Specifically, I'm trying to get the duet board to communicate with the Nordson Ultimus V, and I'm not sure if the Uart handles only 3.3V, or handles 5V. Thanks

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.

Duet 3
RepRapFirmware version: 3.4.4
Duet Web Control v3
Printer architecture: Cartesian

Problem: 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

Here is where the wires are connected on the Duet board

Here are the wires on the accelerometer side
