3.2 Step-by-Step Laser Engraver Calibration Process
Follow these detailed steps to calibrate your ComMarker engraver for 0.001mm precision:
- La configuration initiale:
- Turn on your ComMarker engraver and launch your calibration software (par exemple., LightBurn or EZCad2).
- Ensure all mechanical parts are secure and the workspace is clean.
- Focal Length Adjustment:
- Use the dual red-light focus system to align the laser beam with the calibration template.
- Slowly adjust the focus until the two red spots converge into one. This indicates the optimal focal point.
- Lock in the focus settings once achieved.
- Beam Alignment:
- Activate the laser at a low power setting.
- Direct the laser beam onto a marked calibration target.
- Adjust the galvanometer mirrors manually until the beam is centered and uniform across the target.
- Check alignment at multiple points across the engraving area to ensure consistency.
- Power Calibration:
- Set the laser to the recommended power (par exemple., 75% for the ComMarker B4-20W).
- Engrave a test pattern on a sample material.
- Measure the engraving depth using a micrometer and adjust the power settings to achieve consistent results across the pattern.
- Speed and Frequency Calibration:
- Configure the engraving speed (par exemple., 1000 mm/sec) et fréquence (par exemple., 30 kHz).
- Run a test engraving and observe the quality. If the engraving appears uneven or too shallow, adjust these settings incrementally.
- Repeat the test until the engraving is uniform and meets the desired specifications.
- Line Interval and DPI Adjustment:
- Set the line interval (par exemple., 0.025millimètre) and DPI (par exemple., 1000) to ensure fine resolution.
- Engrave a detailed pattern and examine the inter-line consistency. Adjust if necessary to avoid overlaps or gaps.
- Engraving Angle and Passes:
- Experiment with the engraving angle (par exemple., 45°) to enhance the 2.5D effect.
- Determine the optimal number of passes (par exemple., 100) required to achieve the desired engraving depth without compromising detail.
- Document the settings for future reference.
3.3 Using Test Patterns for Fine-Tuning
Implement test patterns specifically designed for calibration:
- Grid Patterns: Engrave a grid pattern to verify uniformity in engraving depth and spacing.
- Gradient Patterns: Use grayscale gradient patterns to assess the 2.5D effect and ensure smooth transitions between different depths.
- Text and Fine Lines: Engrave a sample text or intricate line design to evaluate micron-level accuracy and detail.
3.4 Adjusting Focal Length and Beam Alignment
Focal length is critical for achieving 0.001mm precision:
- Dual Red-Light Technique: Utilize the dual red-light overlap method to achieve the optimal focus.
- Manual Adjustments: Fine-tune the focus manually, making small incremental adjustments and testing after each change.
- Repeatability: Ensure that the focal point is consistent every time by running multiple test engravings and comparing the results.
3.5 Software Calibration in LightBurn and EZCad2
LightBurn and EZCad2 provide built-in tools for calibration:
