7.5 Sparking from the exit of laser head
1. Check the air blowing tube of the laser head if there is strong air current shoot up, because the air tube is too long
and easy to be bended, blocked or worn out. Solving method: clean or change the white color air blowing tube.
2. Check the air compressor itself if there is something wrong, for example: the air-output is too small; or it doesn’t
work. Solving method: change a new air compressor.
7.6 Water chiller alarming
1.Firstly, ensure the power supply system normally. Low voltage is easily caused water chiller alarming. So we
must make sure the voltage normal; if necessary, chooses the voltage stabilizer.
2.Check the water quantity in the water chiller, less water could cause alarming. Solving method: fill up pure water.
3.Check the water tube if it is bended or blocked, whether the water protection is blocked. Solving method: clean
or straighten the water tube or water protection.
4.Check the water temperature; see if it is much higher than the limited value. Solving method: change the water
often, or restart the machine to engrave after half an hour.

Solving method: Change a new water chiller.
7.7 X or Y axis does not move around or move abnormally.
1. Control card loosen or stoppage.
2. Limit switch or data cable stoppage, check if the limite switch has signal and the cable is connected well.
3. Drive of equivalent axis stoppage, check the drive supply electricity or not, signals is normal or not.
4. Servo motor of equivalent axis stoppage, check the connecting line of the motor short circuit or not; if it is
abnormal, change a motor.
5. Check whether the connecting cable between motor and driver is loosen or connected well or not.
6. Check whether the coupling is damaged or loosen.
7. Equivalent screw rod is broken or the screw of the screw rod stoppage.
8. Equivalent axis’s slide rod stoppage.
9. Driver’s subdivision, electric current are different from the software designed.
