Hello, this is my first Voron build so I do not really know what I am doing. I keep getting this error message (mcu 'mcu': Unable to connect) and I am not really sure why. I can ssh into the printer from the computer and both the Leviathan and Nitehawk board show up when finding the USB ID so it knows they exist? I will attach the klipper file and a screenshot of the error message. lmk if I need to include any other information.
The printer is a LDO voron 2.4 R2 rev D with a raspberry pi 4b.

Two problems stand out in your log.

1. usb-STMicroelectronics_STM32_Virtual_ComPort_3561384D3530-if00 does not sound like a board that's been successfully flashed with klipper firmware.

2. You need to use the full path. So, for example /dev/serial/by-id/usb-STMicroelectronics_STM32_Virtual_ComPort_3561384D3530-if00
