1. Please ensure that the equipment is placed on a stable and level workbench to avoid vibration interference caused by the shaking of the table or equipment during the processing, thereby reducing the impact of vibration on positioning accuracy and processing quality.
2. Before processing, it is recommended to use a lint-free wipe dipped in an appropriate amount of alcohol to clean the field lens protective lens and the material to be engraved, ensuring that the lens and the material surface are clean and free of contamination, thereby reducing optical loss and beam interference.
3. After wiping is completed, please securely place and fix the material to be engraved on the workbench to prevent pattern misalignment, ghosting, or a decline in processing quality caused by material movement or vibration during the engraving process.
1. During the processing, avoid casually touching the equipment body or workbench surface to prevent external mechanical disturbances from introducing vibration errors, which may affect the beam focusing stability and engraving consistency.
2. It is recommended to maintain environmental stability during processing operations, and to minimize the impact of strong airflows (such as direct blowing from fans or air conditioner vents onto the processing area) on optical path propagation and material surface stability, in order to ensure the uniformity of energy deposition and the clarity of imaging.
3. During long continuous processing, attention should be paid to the heat dissipation status of the equipment and the stability of laser output. If necessary, appropriate segmented processing or setting intermittent Cool Down time should be carried out to reduce the impact of thermal drift on the consistency of focal position and engraving depth.
After the carving is completed, if there are still deficiencies in the processing effect, you can troubleshoot based on the typical issues listed in the following table and adjust the process parameters accordingly to optimize the final imaging quality.
| Adverse Effects | Optimization Plan |
| The overall pattern appears whitish or yellowish , with insufficient contrast | Reducelaser power orincrease point cloud spacing |
| Pattern edges are blurred and details are lost | Select a clearer 2D pattern or 3D model to improve 3D slicing accuracy |
| Burring or graininess appears on the edge of the pattern | Reduce scanning speed and increase pulse frequency |
| Local missing or breakpoints occur | Increase the filling density or reduce the point spacing |
| Flickering bright spots or local overexposure occur | Reduce the laser power or pulse frequency |
| Layered stratification or a distinct "stratification sense" is present | Reduce the Z-axis step size and increase the longitudinal filling density |
| The overall offset of the pattern position | Re-execute galvanometer calibration and alignment; check whether the platform coordinate system is consistent with the software parameters |
| Partial misalignment or ghosting of the pattern | Check the galvanometer's return to zero, avoid external vibration interference during the processing, and recalibrate the system |
