Installing klipper on an Udoo Quad with Ubuntu 20.04, I cannot find MCU address (Arduino Due) because of /dev/serial/by-id doesn't exit. Any suggest?
The best long-term solution is trying to fix the udev rules to make /dev/serial/by-id appear. However, the quickest way to get Klipper working now is to: Unplug the Arduino Due. Run dmesg -w and plug it back in. Note the assigned port (e.g., /dev/ttyACM0). Use this temporary port name in your printer.cfg.
