- Level the Machine – After assembly, ensure the machine sits on a flat, stable surface. Check that the X, Y, and Z axes move smoothly without binding.
- Install Control Software – Download and install Candle, UGS (Universal G-code Sender), or LightBurn (laser version). Connect via USB and select the correct COM port.
- Set Zero and Homing – Always home the machine before each job. Set your workpiece zero point (X, Y, Z) carefully. Use a piece of paper to set Z height for engraving bits.
- Start with Simple Projects – Begin with shallow engraving on scrap wood. Test speeds and feeds before running critical projects. Use slower speeds for harder materials.

Warnings and Safety Notes
- Wear safety glasses – Always wear impact-resistant safety glasses when the machine is operating. Chips and debris can fly at high speed.
- Keep hands away – Never touch the spindle, bit, or workpiece while the machine is running. Use the emergency stop button if needed.
- Secure workpiece – Use clamps, double-sided tape, or fixtures to hold the workpiece firmly. Loose material may become a projectile.
- Proper dust extraction – Wood dust, MDF dust, and PCB fiberglass dust can be hazardous. Use a vacuum or dust shoe and work in a ventilated area.
- Bit selection and speed – Use sharp, appropriate bits for each material. Incorrect speeds or dull bits may cause bit breakage or poor cut quality.
- Electrical safety – Do not operate with wet hands. Keep liquids away from the control board, power supply, and electrical connections.
- Supervision required – This machine is not a toy. Do not leave running unattended. Young adults should operate under adult supervision.
- Homing before each job – Always home all axes before starting any program. Failure to home may result in crashes or out-of-bounds movement.
- Laser upgrade caution – If you upgrade to a laser module, always wear appropriate laser safety glasses for the specific wavelength (e.g., 445nm for blue laser).
- Disconnect power for maintenance – Unplug the machine before cleaning, adjusting bits, or performing any maintenance.
