7. Troubleshooting
Refer to these common issues and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Laser not firing | Power cable disconnected, software error, laser module fault | Check power connection, restart software, contact support |
| Engraving is too light | Incorrect focus, low power setting, high speed setting | Adjust focus, increase laser power, decrease speed |
| Material not cutting through | Insufficient power, too high speed, too few passes | Increase laser power, decrease speed, increase number of passes |
| Machine not connecting to computer | USB cable issue, driver not installed, software port error | Check USB cable, install drivers, verify software port settings |
