Raspberry Pi 4 Model B + Duet 3 6 HC

General Discussion

Hello everyone,

I have made the connections between the Raspberry Pi 4 Model B and the Duet 3 6HC board, but the serial port /dev/ttyACM0 does not appear. Am I making the connections incorrectly? Can someone who is knowledgeable in this area help me? Because of this, I am getting the following error:

“mcu ‘mcu’: Unable to connect Once the underlying issue is corrected, use the ‘FIRMWARE_RESTART’ command to reset the firmware, reload the config, and restart the host software. Error configuring printer”

I am using the Duet 3 6HC v1.01 motherboard. I want to control the Duet 3 6HC + 3HC boards through Klipper using a Raspberry Pi 4 Model B. Can you help me with the connection diagrams and make menuconfig configurations?"

I looked but couldn’t find anything about Raspberry and Duet 3 6HC connection cables. Do I need to connect it with TX and RX pins? Can someone who knows this help me?

@EddyMI3D Thank you very much, I solved it, as you said, it communicated with the MCU via USB and microUSB cable.
