 + 
 +● Avoid prolonged exposure to dusty environments 
 + 
 +● If you don't use it for a long time, wrap it up as best as possible and avoid dust affecting machine performance. 
 + 
 +● Put it on a safe place to avoid dropping. 
 + 
 +● Avoid working in a dry environment to avoid damage to the machine caused by static electricity. 
 + 
 +● Add a little of butter on the slide. If you don't use the machine long time.

 +**--1.The machine works, but it doesn'​t carved out?** 
 + 
 +a.Whether the material is suitable for carving, The machine is engraved by burning, so it is impossible to engrave inorganic materials such as stones. In general, materials that can be Burnt black with a lighter can be used for engraving, but plastics that be added Anti-combustion and pure white paper that aasy astigmatism can't be burned. Some paper can't burned because of adding powder or film. 
 + 
 +b.Whether the surface of the engraved material is flat. 
 + 
 +c.Whether the object is fixed well. 
 + 
 +d.Whether the focal length is adjusted accurately. 
 + 
 +e.Is the burning time set properly?​. 
 + 
 +**--2.Why does the machine keep hitting a straight line?** 
 + 
 +The chassis is driven by a stepper motor. If the weight of the load is too heavy, the motor will not be able to complete the drive. Please reduce the weight of the engraving object. 
 + 
 +**--3.The power connection is normal, but the machine does not move?** 
 + 
 +The mechanical structure may be stuck by foreign objects. For the first time, please remove the fixed mechanical EPE. If the machine lacks maintenance for a long time, you can add a small amount of lubricating oil to maintain the mechanical joint. 
 + 
 + 
 +**--4.Laser running to one side?** 
 + 
 +The mechanical joints have sand-sized foreign bodies that affect the mechanical work, and can quickly slide back and forth to eject foreign objects. 
 + 
 +**--5.Some parts cannot be carved?** 
 + 
 +It may be that there is a foreign object inside the laser tube that blocks the light path output. You can remove the focusing mirror to check if there is any foreign matter. 
 + 
 +**--6.Have a ghost.** 
 + 
 +It may be that the engraved object is not fixed, and the displacement occurs when engraving. Please place a silicone anti-slip pad under the engraved object and fix it with a rubber band. 
 + 
 +**--7.Carving half.** 
 + 
 +It may be that the mechanical structure has been displaced during engraving. Please turn off the power of the machine and restart it, so that the machine can be reset again, and avoid the displacement of the bottom plate or laser during the operation. 
 + 
 +**--8.Engraving depth is not enough.** 
 + 
 +The material to be engraved, whether the surface of the material is flat, whether it is fixed and flat, whether the focal length is adjusted accurately, whether the burning time is appropriate,​ and the number of repeated engravings will affect the engraving depth. Please adjust according to the above actual factors. 
 + 
 +**--9.Why are some white papers not carved?** 
 + 
 +Some white papers are too thin, with flame retardant lime powder, or a plastic film on the surface. These will affect the focus and energy burning. It is recommended to use gray cardboard as the test material. 
 + 
 +**--10.Why are some woods not carved?** 
 + 
 +All wood can be engraved, please ensure that the surface of the wood is fixed parallel to the laser burning surface, and the curved wood may not work well due to the change of focal length. 
 + 
 +**6.About laser head!** 
 + 
 +Solid laser head: There'​s life span for the laser head , and laser type normally are CO2, Multimode high power laser, small solid-state laser, Our DK-BL uses Nichia blue 405nm single-mode laser diode, the official service life is 10000 hours, the normal use in about 3 months -1 years, but it's also closely related to how you use it .(main factors include : The temperature,​ time intensity, current, voltage, anti static treatment, adverse rate etc. )The laser module quality control technology 
 + 
 +Laser module quality control process: The laser modules used by Our DK-BL is the best one that with constant current drive modules, along with a stable cooling system. And every single-mode module has being through 3 hours aging tested. and are well packaged before outgoing. So the machine that every user received had PASS a serial of reliability test. but even so, there may be 0.05% chance that the machine you receive may have the laser durability problem. In this case, please confirm within 3 days, and feed back to the dealer, we can arrange replacement for you for free. 
 + 
 +What about the laser head life? There’s service life for all laser products, the laser tube official life is 100,000 hours, but the actual life will depends on actual usage. In general, 3 Month - 1 year, or may be many years. 
 + 
 +How to ensure the life of the laser? In order to protect the life of the laser, We do not recommend long-times use. 
 +How to judge the laser head burned? 
 + 
 +1.When the machine is working, the light was significantly weakened. 
 +
