Unboxing and setting up a new 1325 laser cutter can be daunting. This powerful machine requires careful preparation to ensure its first job—and every job after—is a success. Follow this step-by-step guide to go from a powered-down machine to making your first cut safely and efficiently.

⚠️ Safety First! Before you begin, always wear appropriate Personal Protective Equipment (PPE), like laser safety glasses. Never operate the laser cutter unattended, and always have a fire extinguisher rated for electrical and combustible materials (like a CO2 extinguisher) nearby.

Phase 1: Unboxing and Initial Setup

Step 1: Unpack and Inspect
Carefully uncrate the machine. Check for any visible shipping damage to the chassis, laser tube, lenses, or linear guides. Report any damage to the supplier immediately. Ensure all components, including the water chiller, air assist pump, and exhaust fan, are present.

Step 2: Assemble the Cooling System
The laser tube must be water-cooled to prevent overheating and catastrophic failure.

• Place the water chiller near the machine.
• Connect the water inlet and outlet hoses from the chiller to the laser tube's corresponding ports. Crucially: Ensure the water flow direction is correct (usually marked on the laser tube; inlet goes to the bottom port).
• Fill the chiller with distilled or deionized water to prevent mineral buildup.
• Turn on the chiller and check for leaks. You should see a steady, bubble-free flow of water through the tube.

Step 3: Connect Air Assist and Exhaust

• Air Assist: Connect the air compressor or air pump to the machine's air inlet. Air assist blows away smoke and debris from the cut, resulting in cleaner edges and reducing the risk of fire.
• Exhaust: Connect the exhaust port on the laser cutter to your ventilation system or fume extractor using appropriate ducting. Proper ventilation is essential for removing harmful fumes created during the cutting process.

Step 4: Position and Level the Machine
Place the machine on a stable, level surface. Use a spirit level to check the bed. An unlevel machine can lead to focusing issues and inconsistent cuts across the large bed.

Step 5: Electrical Connection
Plug the main machine, chiller, air pump, and exhaust fan into appropriate power outlets. Ensure your voltage and phase requirements (commonly 220V single-phase) match your power supply. Use a grounded outlet.

Phase 2: Software and Control System Setup

Step 6: Install the Control Software
Your 1325 laser likely uses a DSP controller system (like Ruida, TopWisdom, or Leetro). Install the corresponding software on your computer (e.g., LightBurn, RDWorks). LightBurn is highly recommended for its intuitive interface and powerful features. Install the necessary USB drivers so your computer can communicate with the laser's controller.

Step 7: Connect and Test the Controller

• Connect the computer to the laser cutter's control panel via USB or Ethernet.
• Turn on the main power switch on the laser cutter.
• Open your laser software and look for a connection indicator. You should be able to see the machine's status and, crucially, control the laser head movement from the software.

Phase 3: Critical Calibrations (Before Your First Cut)

Step 8: Align the Laser Beam (Mirror Alignment)
This is the most critical calibration step for performance and safety. A misaligned beam will lose power and can damage the machine.

1. Place a piece of masking tape over the first mirror (nearest the laser tube).
2. Press the Pulse button (or a low-power test fire) in the software. This will mark the tape.
3. Move the laser head to the far corners of the bed, repeating the pulsing on tape over the second and third mirrors.
4. The goal is for the burn mark to be in the exact center of each mirror at all positions. Adjust the mirror alignment screws until it is. Consult your machine's manual for detailed mirror access.

Step 9: Focus the Laser Lens
A correctly focused laser produces the finest, most powerful cut.

• Place your material on the honeycomb bed.
• Use the Focus Tool (often a metal or plastic block of a set height). Place it on the material, and jog the Z-axis down until the laser nozzle just touches the top of the focus tool.
• Alternatively, you can manually measure the distance from the nozzle tip to the material surface. The correct focal length is specific to your lens (e.g., 2.0 inches for a 2" lens).

Phase 4: Preparing and Running Your First Job

Step 10: Load Your Design and Set Parameters

• In your laser software, import or create your design (e.g., a simple square or your logo).
• Assign cutting and engraving parameters to the different layers/colors of your design. Start with the manufacturer's recommended settings for your material (e.g., for 3mm acrylic: Power 50%, Speed 20mm/s). You will need to test and create your own material library over time.

Step 11: Set the Origin Point

• Manually move the laser head (using the software's jog controls) to where you want the job to start—typically the top-left corner of your material.
• Click "Set Origin" or "Home" in the software. This tells the machine, "Start the job from right here."

Step 12: Run a Frame Test

• This is a vital safety check. Use the "Frame" command in the software.
• The laser head will travel around the outline of your entire design without firing the laser. This confirms that your design fits on the material and is within the machine's boundaries.

Step 13: Start the Job

• Put on your safety glasses.
• Ensure the water chiller, air assist, and exhaust fan are running.
• Press the "Start" button on the software or the machine's control panel.
• Keep a close watch, especially during the first minute, ready to hit the Emergency Stop button if you see flare-ups or unexpected behavior.

Post-Process and Maintenance

• After the Job: Wait for the machine to complete its cycle and for any fumes to clear. Carefully remove your finished part.
• Clean the Lens: Use lens cleaning solution and lens tissue to gently clean the focusing lens. A clean lens is essential for maintaining maximum laser power. Do this regularly.
• Clean the Bed: Brush off debris from the honeycomb bed to ensure a flat surface for the next material.

By meticulously following these steps, you will build a solid foundation for safe, efficient, and high-quality operation of your 1325 laser cutter. Remember, patience during setup pays dividends in the quality of everything you create afterward. Happy cutting
