1. Please wear laser goggles during usage and avoid touching the laser directly with your eyes and skin!
2. Do not engrave mirror objects，Pay attention to fire，Pay attention to pets when working！
3. Smoke will be generated when burned, please pay attention to smoke exhaust indoors.
4. The warranty period of laser module is one year. If you have any quality problem(Except individual situation like using the laser module more than 30 minutes per time and casue the damage ), please feel free to ask our customer service for a help.
5. If your laser module has any problem, please DO NOT dismantle it without our permission. It will destroy the laser module.
6. If you have any quality problem about the machine, please feel free to contact us. Many operative problem can be solved according to your video and problem description. Thank you in advance.
7. It can also be compatible with other cnc equipment, such as 3d printers, CNC MIlling, etc., but you need to master a certain knowledge of pwm waveform control.
