3. Mechanical Assembly and Calibration

3.1 Assembling the Components

Follow the instructions in the user manual for assembling the ComMarker Omni 1:

• Step 1: Lay out all parts and tools.
• Step 2: Secure the supporting poles and attach the laser head to the designated shelf.
• Step 3: Connect the necessary cables (galvanometer, power, and data cables) as per the diagram.
• Step 4: Connect the water chiller if applicable, ensuring all tubes are securely attached and leak-free.

3.2 Initial Calibration of the Laser Head and Focus

Achieving proper focus is essential for stainless steel engraving:

• Dual Red-Light Focus: Activate the laser’s dual red-light system. Adjust the laser head until the two red spots overlap perfectly on a calibration target.
• Lock Focus Settings: Once the optimal focus is reached, secure the laser head to prevent movement during operation.
• Test Calibration: Run a quick test pattern on a sample material to confirm that the focus is accurate.

4. Connecting and Configuring Software

4.1 Installing EZCad2/LightBurn

• Download and Install: Obtain the latest version of EZCad2 or LightBurn from the official website. Follow the installation instructions carefully.
• Driver Setup: Ensure that the necessary drivers for the Omni 1 are installed on your computer.
• Software Configuration: Open the software and connect it to your laser engraver via USB or Wi-Fi.

4.2 Importing Calibration Files and Setting Up Your Workspace

• Import Calibration File: Use the built-in calibration feature in your software. Import the calibration file provided in the user manual.
• Workspace Setup: Adjust the working area in the software to match the physical dimensions of your laser engraver.
• Test Run: Perform a calibration test to verify that the software and hardware are properly synchronized.

5. Optimizing Laser Parameters for Stainless Steel Engraving

5.1 Recommended Settings Overview

For stainless steel marking, precise settings are essential to avoid overheating and ensure clean, permanent engravings. For the ComMarker Omni 1:

• Engraving Speed: 1000 mm/sec
• Laser Frequency: 30 kHz
• Laser Power: 75%
• Line Interval: 0.025 mm
• DPI: 1000
• Engraving Angle: 45°
• Passes: 100

5.2 Adjusting Power, Speed, and Frequency

• Laser Power Adjustment:
  • Start at 75% power for stainless steel.
  • Monitor the engraving; if excessive burn marks appear, lower the power incrementally.
• Speed and Frequency:
  • Set speed to 1000 mm/sec for efficient marking.
  • Use a frequency of 30 kHz to balance speed with precision.
• Fine-Tuning:
  • Experiment with slight adjustments and document the outcomes.
  • Use LightBurn’s preview mode to visualize how changes affect the engraving depth and detail.

6. Test Engraving and Fine-Tuning

6.1 Running a Test Pattern

• Select a Standard Test Pattern:
  • Choose a test design that includes various details such as fine lines, gradients, and text.
• Engrave on a Sample Piece:
  • Use stainless steel offcuts to run your test pattern.
• Evaluate Results:
  • Check for uniformity, clarity, and depth.
  • Note any areas with burns or uneven engraving.

6.2 Analyzing Results and Making Adjustments

• Identify Issues:
  • Look for signs of overburning or carbonization.
  • Check for inconsistent line spacing or incomplete engraving.
• Parameter Tweaks:
  • Adjust laser power, speed, or frequency based on the observed issues.
  • Re-run the test pattern until the engraving meets the desired quality.
• Document Successful Settings:
  • Save the settings profile in LightBurn for future projects.

7. Troubleshooting Common Issues

7.1 Calibration and Focus Problems

• Issue: Laser not properly focused
  Solution: Revisit the dual red-light focus system. Adjust slowly until the red lights converge accurately on your calibration target.

7.2 Inconsistent Engraving Depth

• Issue: Variation in engraving depth across the test pattern
  Solution: Check and re-align the galvanometer mirrors. Verify that the laser power remains stable throughout the process.

7.3 Overheating and Carbonization

• Issue: Signs of burning or carbon buildup on stainless steel
  Solution: Lower the laser power slightly and increase the frequency. Ensure the cooling system is functioning correctly.

7.4 Software-Related Issues

• Issue: LightBurn preview does not match the final engraving
  Solution: Re-import calibration files and adjust the offset and angle parameters as needed. Check for software updates that may resolve the discrepancy.
