      How to Find Optimal Focus for Your Laser (EzCad 2)

      This guide explains how to find the optimal focus for your laser using EasyCAD. The steps include performing a focus test, calibrating the red line, and ensuring accurate scaling for precise engraving.

      Step-by-Step Instructions

      1. Setup for Focus Test

        • Open EasyCAD and use a piece of scrap metal or another suitable substrate for the focus test. Metal is preferred as it produces visible sparks when in focus.

      2. Draw a Rectangle

        • Use the rectangle tool to draw a long, skinny rectangle in the center of the screen.
        • Hatch the rectangle at 0.02 mm, which is suitable for metal substrates.

      3. Set Parameters

        • Go to the parameter settings and select the appropriate parameters from the library, such as NFA Steel.
        • Ensure continuous marking is enabled and set the number of passes to more than one.

      4. Mark the Rectangle

        • Start marking the rectangle and adjust the focus knob to find the optimal focus. Look for the point where sparks are most intense and the engraving is clear.

      5. Find Optimal Focus

        • Identify the high and low points of focus and determine the optimal focus by finding the midpoint between them.
        • Mark this focus point on a reference stick for future use.

      6. Calibrate the Red Line

        • Use a legal pad or similar substrate to draw a 4x4 inch square. Ensure the aspect ratio is unlocked and the square is centered.
        • Mark the square and use the red line to check alignment.

      7. Adjust Offsets

        • If the red line is not aligned with the marking, adjust the X and Y offsets in EasyCAD. Use positive or negative values to move the red line as needed.
        • Repeat the process until the red line matches the marked square.

      8. Verify Scaling

        • Measure the marked square with calipers to ensure it is 4x4 inches. Adjust the scaling in EasyCAD if necessary to achieve accurate dimensions.

      Conclusion

      Finding the optimal focus for your laser involves performing a focus test, calibrating the red line, and verifying scaling for precise engraving. Follow these steps to ensure your laser is properly focused and calibrated. For further assistance, refer to EasyCAD documentation or support channels. Happy engraving!
