4. Operating Instructions
4.1 Material Preparation and Focusing
Place your chosen material flat on the working surface. Use the included 2mm clear/frosted plastic tool to set the correct focal length. The laser needs to be a specific distance from the top of the material for optimal focus. Adjust the laser module height until the tool fits snugly between the laser and the material.
4.2 Engraving and Cutting Parameters
Optimal engraving and cutting results depend on the material type, power, and speed settings. Refer to the table below for recommended parameters for common materials. Adjust power and speed based on desired depth and material characteristics.

5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your Comgrow Z1.
- Laser Lens Cleaning: Periodically clean the laser lens with a soft, lint-free cloth and a small amount of isopropyl alcohol. Ensure the lens is free of dust and debris to maintain laser precision.
- Rail and Belt Inspection: Check the X and Y-axis rails and belts for any signs of wear, looseness, or obstruction. Keep the rails clean and lubricated if necessary.
- General Cleaning: Wipe down the machine's frame and components regularly to prevent dust buildup, which can affect performance.
6. Troubleshooting
If you encounter issues with your Comgrow Z1, refer to the following common troubleshooting tips:
- Machine Not Connecting: Ensure the USB cable is securely connected to both the machine and the computer. Verify that the correct drivers are installed and the software (LaserGRBL/LightBurn) is configured with the correct COM port and baud rate (e.g., 230400).
- Poor Engraving Quality: Check the laser focus. Ensure the material is flat and properly secured. Adjust power and speed settings according to the material and desired effect (refer to Table 1). Clean the laser lens if the output appears weak or inconsistent.
- Skipping or Misalignment: Inspect the X and Y-axis belts for proper tension. Ensure the eccentric nuts on the gantry are adjusted correctly to eliminate any play. Check for obstructions on the rails.
- Laser Not Firing: Verify that the laser module is correctly installed and all wiring connections are secure. Check the power supply.
