- Refer to the following article to check if the laser module is correctly connected:
- Unlock the main control box with the safety key before using the machine:
- Check if the enclosure cables are securely connected; check if the enclosure door is closed.
If you want to use the machine without installing the enclosure, disable the door detection option in Luban, please pay attention to safety when you do so!
Solutions for stopping during the job with a red light:
- Observe if there is a flame during the job; adjust the sensitivity of the flame sensor appropriately to reduce sudden job stops caused by flame sensor triggering, the sensor is less sensitive when the number is lower (range: 0-4095).
- Observe if the laser module is overheating; check if the cooling fan is operating normally.
