Note(Please pay attention):
1. Please wear laser goggles during usage and avoid touching the laser directly with your eyes and skin!
2. Do not engrave the mirror objects or the metal with strong mirror reflectivity, which may cause injury to the operator or burn the laser.
3. Supported engraving materials: Wood, gray paper, leather, bamboo, blackening plastics, rubber, alumina oxide, etc. Can not work on the stainless steel, alloy, glass, and some reflective materials.
4. Especially good at cutting, It can cut wood (3-8mm). It supports engraving alumina oxide, and other non-reflective materials, depth of engraving (0.5-3mm wood).
5. Laser diode is a sensitive component, pay attention to prevent electrostatic damage (product includes electrostatic protection design, but there is a certain probability of damage).
6. Need to switch to the CNC Mode to cutting.
7. Pay attention to fire, pay attention to pets when working.
4. Smoke will be generated when burned, please pay attention to smoke exhaust indoors.
8. If your laser module has any problem, please DO NOT dismantle it without our permission. It will destroy the laser module.
9. 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.
