2. Safety Information

Operating a laser engraving and cutting machine requires adherence to strict safety protocols to prevent injury and damage. This machine is a Class 1 laser product with an output power of 0.386 mW, but the internal CO2 laser tube is significantly more powerful and requires caution.

• Eye Protection: Never look directly into the laser beam or at the laser spot during operation without appropriate laser safety glasses. The machine features a protective lid with a safety interlock.
• Lid Interlock: The laser is equipped with a locking device that automatically turns off the laser when the lid is opened during operation. Do not bypass this safety feature.
• Ventilation: Ensure proper ventilation is in place to remove fumes and smoke generated during cutting and engraving. The machine includes an exhaust fan.
• Fire Safety: Keep a fire extinguisher nearby. Some materials can ignite during laser processing. Never leave the machine unattended while operating.
• Electrical Safety: Ensure the machine is properly grounded. Do not operate with wet hands or in damp environments.
• Material Safety: Only process materials approved for CO2 lasers. Avoid materials that produce toxic fumes or are highly flammable.

4. Setup

4.1 Unpacking and Placement

1. Carefully remove the machine from its packaging.
2. Place the machine on a stable, level surface in a well-ventilated area. Ensure sufficient space around the machine for operation and maintenance.
3. Connect the ground wire to a proper electrical ground.

4.2 Connecting Peripherals

1. Water Pump: Connect the water pump to the designated inlet and outlet ports for laser tube cooling. Ensure the water reservoir is filled with distilled water. The self-developed built-in circulating water cooling system requires proper connection of the external pump.
2. Exhaust System: Connect the provided vent duct to the exhaust fan outlet and direct it to an outdoor vent or a suitable filtration system. The machine has a built-in exhaust fan.
3. Air Pump: The air pump is built-in. Ensure its connection is secure. Air assist helps clear debris and reduce scorching during cutting.
4. Power Connection: Connect the power cord to the machine and a grounded 110V AC power outlet.

4.3 Software Installation and Connection

1. Install the provided software (e.g., LightBurn, RuidaDraw) from the USB stick or CD onto your computer.
2. The machine is compatible with Windows 10, 8, 7 (64/32 bit), XP, 2000, VISTA. It is NOT compatible with iOS systems.
3. Connect the computer to the laser machine using the provided USB cable or network cable.
4. Supported design software includes LightBurn, CorelDRAW, AutoCAD, and Illustrator.

5. Operating Instructions

5.1 Basic Operation Flow

1. Design: Create or import your design using compatible software (LightBurn, CorelDRAW, AutoCAD, Illustrator).
2. Material Placement: Place the material on the appropriate work platform (honeycomb or knife strip). The machine features a large working area of 1400x900mm with integrated input and output, allowing for processing of extra-long objects.
3. Focus Adjustment: Adjust the laser focus according to the material thickness. The machine has an autolift bed with an electric lifting height adjustable up to 22cm. A red pointer is present for precise positioning.
4. Transfer File: Transfer the design file to the machine via USB cable, network cable, or USB flash drive.
5. Control Panel: Use the Ruida controller (RD6445) to set parameters and initiate the job.
6. Start Operation: Ensure all safety precautions are met, then press the start button on the control panel.

5.2 Work Platforms

The machine includes two types of working platforms:

• Honeycomb Platform: Composed of small, honeycomb-shaped holes, this platform allows the laser beam to penetrate the material more effectively, improving work efficiency and cutting quality.
• Knife Strip Platform: This platform helps reduce reflections from the back of the material, resulting in cleaner cuts and engravings.
