How do I copy and paste the settings of aixs0 to axis1 using odrivetool?

You can use odrivetool backup-config config.json, which will dump all of the ODrive’s configuration to config.json. Then, you can just find and replace axis0 to axis1 (and remove duplicates), then run odrivetool restore-config config.json
