What It Can't Do
- •Avoid installing as root; if necessary use '--unsafe-perm' flag to avoid serialport build issues. 2. Make sure serial port baud rate matches your controller. 3. 3D visualization may be slow on low-end devices. 4. Not all controllers support all features (e.g., TinyG firmware version matters).
Use Cases
- Control a CNC machine from a web browser on any device in the local network
- Replace a basic serial terminal with a rich GUI including 3D preview and advanced features
- Build a portable pendant with Bluetooth gamepad or wireless numpad
