6.Use the command ~/klippy-env/bin/python ~/klipper/scripts/canbus_query.py can0 to query the uuid.

7.Three IDs will appear, listed above: the mainboard MCU, the printhead MCU, and the auxiliary feed MCU. After searching, compare the IDs. If any ID is missing, there may be a problem with the corresponding module. Troubleshoot that module separately.

8.Enter Mainsail, open Print.cfg, restore the modified UUID from step 3, and click SAVE & RESTART in the upper right corner.

9.You can also use ifconfig and lsusb commands to check whether the connection is normal.
