Driver Installation
The 4G U disk provided includes necessary drivers for Windows XP, SP3, Win 7, Win 8, and Win 10 (32/64 bit). Install these drivers before connecting the machine to your computer via the USB port.
Safety Precautions
CNC machines are inherently hazardous. Always turn off the power to the spindle when working around the spindle, such as changing bits or adjusting the workpiece. Observe all safety precautions that came with your CNC machine, including the wear of safety goggles, appropriate clothing, and gloves. If you are new to CNC, always prioritize safety and familiarize yourself with the machine's operation before attempting complex tasks.

Operating Instructions
The CNCTOPBAOS 3018 CNC Router can be operated via a computer using GRBL control software (such as Candle or UniversalGcodeSender) or through the included offline controller.
Offline Controller Operation
The offline controller supports SD and TF cards (standard 1G capacity included). It allows direct control of the machine without a computer connection. The menu page allows selection between machine control (Ctrl) and file operations (File). The control page enables moving axes (X±, Y±, Z±) and spindle control (OK/Spindle). Step size can be changed using Exit/Step. To adjust spindle power, press OK and Z+ (increase) or Z- (decrease) simultaneously. The file page allows selecting G-code files (.nc/.txt/.tape/.gcode) for engraving. Long press Exit to stop machining.
This image details the various screens and buttons on the offline controller, including the menu, control, and file pages. It illustrates how to navigate the interface to control machine movements, spindle operation, and file selection for engraving tasks.

Computer Software Operation
The machine supports GRBL controller software on Windows XP, SP3, Win 7, Win 8, and Win 10. The software allows for precise control, G-code loading, and monitoring of the machine's status. Ensure the serial cable is connected to your controller and select the correct COM port in the software. If using the offline controller, disconnect it from the machine before connecting to a computer, and vice-versa.

Supported Materials
The CNC router can engrave plastic, wood, acrylic, PVC, PCB, and similar materials. It can also work with soft metals like copper and aluminum. Note that it cannot carve hard metals, jade, or other very hard textures. If you change the spindle to a laser module (not included), you can also carve kraft paper, leather, and bamboo.
This image showcases the versatility of the CNC router by displaying various materials like MDF, PCB, acrylic, wood, leather, and rubber, along with examples of engraved or cut designs on each. It also illustrates the use of different bits for specific tasks.
Maintenance
Regular maintenance ensures the longevity and precision of your CNC router. Keep the machine clean from dust and debris, especially around the lead screws and linear rails. Periodically check all bolts and connections for tightness, as vibrations during operation can cause them to loosen. Lubricate moving parts as recommended in the detailed user manual on the provided U disk to ensure smooth operation and prevent wear.
Troubleshooting
Common issues may include loose parts, which can affect accuracy and machine stability. Always ensure all components are securely fastened. If you experience issues with the control board or software, refer to the troubleshooting section on the provided U disk. Some users have reported issues with parts length or machining quality; in such cases, contacting customer support or referring to community forums for solutions may be helpful.
