Questions and answers
how to see the file system of cb1 using Mac
To access the file system of the BIGTREETECH CB1 using a Mac, you can use an SSH connection or a USB/SD card reader:
` (replace `` with the actual IP).
1. SSH Access (Preferred Method):
- Ensure the CB1 is powered on with the Klipper image installed and connected to the same network as your Mac.
- Wait for the green LED to start flashing (indicates CB1 is running).
- Find the IP address of CB1 using your router’s device list or a network scanning tool.
- Open Terminal on your Mac and type: `ssh pi@
- Default password is usually `raspberry` unless changed.
2. Using SD Card Reader:
- Power off the CB1 and remove the micro SD card.
- Insert the SD card into your Mac using a card reader.
- The boot partition should mount automatically, allowing limited access to the file system.
3. UART Debugging (Optional):
- Use a USB-to-serial adapter and connect to UART0.
- Use a terminal app like MobaXterm (via another PC) or screen/minicom on Mac.
- This allows low-level access for debugging if SSH is not available.
Make sure the correct fdtfile and console settings are used in the configuration if you're using UART or HDMI.
