/FAQTroubleshooting of Laser Engravers
Ⅰ. No laser from the laser tube? To settle it by the following steps:
STEP 1. Make sure if the water pumpe is in good condition and if there is water flowing when working.
STEP 2. Make sure if the laser supply is working regularly(check out the fan) .
STEP 3. If all the above mentioned are working regularly, to press the button “Laser” to make sure if there is laser shooting out from the laser tube. In the meantime, you can check if there is any crack on the laser tube. There maybe something wrong with the laser tube if you can not see the laser, but you find crack on the laser tube.
STEP 4. Check the power supply and Non-water Pretection System (to make sure whether the fuse is burned out).
Ⅱ.If any dislocation phenomena occurs when the laser engraving machine is working, to resolve it by the following steps.
STEP 1. check the reflection of laser, to make sure whether it is regular
STEP 2. Check the ground electrode, pay sttention to disturbing from the Electrostatic.
STEP 3. Check the setup of the software of laser engraving machine, be sure it matches with the size of the working area of worktable.
STEP 4. Check the documents for engraving you made, to make sure the size you set matches with what you are going to engrave or cut, you can make a try of engraving or cutting a picture or a square.
STEP 5. Check the degree of tightness of belts and driving Wheel.
STEP 6. If there is something wrong with the Driver of X-Axis or Y- Axi, you have to change it.
Ⅲ.If you find the light of laser weak, to resolve it by the following steps.
1. Please check if the line of laser is right or the lens and mirrors are clean.
2. Check the using time of the laser tube.
3. Open the laser software, click “Open laser”, or click “Test laser”, set the power more than 80w, click “Open laser”, check out the temperature of laser.
Ⅳ. Does not work, not in Normal Working, dislocation and so on, to resolve it by the following steps.
1. Check the machine according to the dislocation.
2. Check the mainboard.
3. Check if the computer infected a virus and if the file you set was too large.
Ⅴ. Can not connect with the computer, to resolve it by the following steps.
1. Check if the connector which the machine connects with the computer is loose
2. The size of the file we set is larger than the Total memory of the machine, especially the AV format.
3. Check if the size of the file we set is larger than the working area of the machine,
Ⅵ. Can not read the USB Flash.
1. Check the quality of the USB Flash.
2. Check if there are many files in the USB Flash, principlely speaking, the mianboard can not recognize “Folder”, but read one file with mol format.
3. The size of the file in the USB Flash is too large.
4. There is virus in the USB Flash, you should format the USB Flash and stock one file with mol format.
5. There is something wrong with the mianboard.
Ⅶ. Can not install the software
1. There maight be something wrong with the computer, choose another one and try again, or check if your computer infected a virus.
2. Install with backup sofeware
Ⅷ. Change the laser tube
Step 1. You should turn off the power, then heat the weld of the laser tube by using electric iron, do not weld so long, or the laser tube will be broken.
Step 2. Export the water or pull up the water pipe, then change a new tube. Keep some distance between the lighting end of laser tube and the first len, then connect up the water pipe, turn on the power supply of water pump.
Ⅸ. Change the laser power
This procedure is rather easy to operate.
Step 1. Turn off the power.
Step 2. Find the interface of cathode and disconnect it, take down the laser power.
Step 3. Change a new one to replace the old, fix it and connect the positive and negative charges.
Ⅹ. Install the Rotary attachment
Step 1. put down the working table to the bottom, then install the rotary attachment, after doing this, you can put the material you want to engraving under the laser head.
Step 2. Turn off the machine and cut down the power supply, remove the plug of Y-axis driver(reserving the 2-pin plug, because it is the power wire of the driver), then plug the rotary attachment.
Step 3. Turn on the power of the machine and test the machine, the guide rail Y-axis is the rotary attachment at this time, so you must put the guide rail on the suitable place before removing the plug of Y-axis driver.
Attentions:
1. In order to prevent the tube from frost damage in winter or in the place cold, you should exhaust the water from the laser tube thoroughly.
2. The water flowing in the laser tube should be clean, the sundries and water scale will affect the machine working smoothly.
3. Check if the water is flowing in the laser tube before the startup of the machine.
4. The time will not be long when you are welding the laser tube, and do not touch the tube. There is not burr in the weld, and when you finish welding, stick the weld with the tape in order to prevent the weld from touching the air, that makes the possibility of sparking under high Voltage.
5. Keep your lens and mirrors clean and complete all the time, wipe them by using cotton swab with alcohol.
6. In order to prevent the machine from disturbing, you sould install the ground electrode.
7. You should install a voltage stabilizer if the voltage is not steady in the working place, by doing so, that will protect the laser tube and laser power from damage.

Troubleshooting of CNC Router SC2518
1. What kind of software does your machine support?
The standard software Compatibility is Type3, it’s optional.
2. Does your machine SC2518 can work offline?
Sure, if you required for this we can do accordingly. Just it will cost more. In this situation, we will introduce our SIC-330 for you. Since SIC-330 is higher in quality and resolutions than SC2518. It will be more valuable with offline Control System NC STUDIO.
3. Why sometimes the PC and the machine will be disconnecting?
Since the computer is aggrieved easily by the virus. So we suggest that:
1) The computer which used to serve for the machine would better not be connected to the outside screen to protect it from computer virus.
2) During processing materials, you’d better not do others with this working computer, or it will stop suddenly.
4. Dose your machine have CE certificate?
Yes, we have. And with CE certificate, our machines have been exported to many countries in North America, Europe, South America and Africa, Asia and so on.
5. The temperature is high in our country all the year round, what kind of spindle is more appropriate here? Water-cooling spindle or air-cooling spindle?
Water-cooling spindle is more suitable for you. Since the temperature in your side is high, so does the temperature of the air. Water-cooling spindle will be better.
6. The spindle temperature is higher when engraving/cutting for long time, what shall we do for it?
1) If the machine has water-cooling spindle, please change the water.
2) If the machine has air-cooling spindle, please let it have a break.
