Before your work begins

Step 1: Get the Wood Ready and Place the Wood on the Laser Bed

Select a wood sheet suitable for laser cutting (e.g., 3–6 mm plywood). Place it flat on the laser bed. Secure it with pins or clamps so it doesn’t shift during cutting.

Tips:There are three common types of pins: T-shaped, L-shaped, and F-shaped. A special use for F-shaped pins is clamping up the plywood to prevent burn marks. Be mindful of the height of the magnets and pins. If they are too tall, the sensor might hit them and become damaged during processing.

Step 2: Open the File and Check the Settings

Import the wooden chess design in Lasermaker and check if your material is large enough. Double-check everything, and decide if you want to add or subtract elements according to your preferences. For the laser cutting layers, pay extra attention to the power setting.

Step 3: Focus Your Laser Machine

Proper focusing is essential for achieving crisp engravings and smooth cuts. If your machine supports auto focus, a single click will set the correct distance for flat wooden boards. If you prefer manual focus, use the focus stick to adjust the laser head until it just touches the surface of the wood at a perfect vertical angle. Spending an extra moment on accurate focusing will pay off with professional-looking results.

Step 4: Frame the Design and Start Laser Cutting

Use the software’s “Frame” function to outline the engraving and cutting area. Make sure the projected frame matches your wood sheet.

Step 5: Monitor the Laser Cutting Process

Stay close to the machine while it’s running and watch the cutting and engraving progress. Keep an eye out for excessive smoke, small flame-ups, or any movement of the material that could affect the outcome. Make sure your workspace is well-ventilated, and rely on air assist if available to achieve cleaner edges on the wood.

Step 6: Complete the Task

Once the laser job is complete, carefully remove the heart-shaped puzzle from the bed. Inspect each piece and gently remove any wood residue. Your puzzle is now ready to be shared or gifted!
