FAQ about the CO2 laser macbine during the using and how to solve?(二)


六、Different depths of bottom when engraving.

1)The processing speed is too fast, the engraving power of the laser tube is too small, adjust the engraving speed and increase the engraving power in time.

2)Incorrect blowing air pressure causes the processing powder to stick and form horizontal line protrusions.

3)The optical path is deviated or the focal length is wrong, resulting in scattered beams and uneven bottom.

4)The selection of focusing lens specifications is unreasonable, and short focal length lenses should be selected as far as possible to improve beam quality.

5)The size of the laser tube is not suitable for engraving or cutting.

6)Whether the scanning accuracy is too small, generally around 0.05-0.08.

7)Check whether the lens is too dirty or damaged, and need to clean or replace the lens. Whether the optical path is offset or not, adjust it in time.

8)Check whether the laser ammeter can reach 16ma, if not, adjust the laser power supply or replace the laser power supply.

9)If the current can reach about 20ma, but the depth is still not enough, it means that the laser tube is aging, and the laser tube needs to be replaced.


七、The phenomenon of missing engraving, random engraving, stop engraving, etc. suddenly occurs during machine processing.


1)Electrostatic interference control board, please check the grounding condition of the machine, and measure whether the ground wire meets the standard (the resistance to ground should not be greater than 5 ohms). If it does not meet the standard, the ground wire needs to be modified to meet the relevant standards.

2)Check whether the connection wire of the control box is loose or the buttons on the control panel are in poor contact.

3)Whether there is strong electricity and strong magnetism at the location of the machine.

4)Check if there are any errors in the original graphics, such as the graphics are crossed, not closed, missing strokes, etc., correct the errors in the graphics, and then output the test.

5)Check whether the laser tube or laser power supply is sparking or disconnect the laser power supply for testing.

6)The problem still exists, test again after replacing the motherboard and computer.


八、Machining dislocation

1)Check whether the XY axis belt is tight or not, adjust the belt tension, and the belt tightness should not be too different.

2)Enlarge the original graphic in the output software to check whether the graphic itself is dislocated. Correct errors in original graphics.

3)Check whether the timing belt is too loose, and whether the belts on both sides of the beam have the same degree of tension. Adjust the tightness of the synchronous belt, whether there is a gap between the motor and the synchronous wheel of the transmission shaft, whether the dark chips of the locking synchronous wheel are loose or against the belt, and tighten the synchronous wheel.

4)Check whether there is an excessive error between the parallelism of the beam and the perpendicularity of the Y-axis.

5)Whether the belt wear is very large, and whether the gears are slipping.

6)The processing speed is too fast, and the step loss phenomenon occurs when the drive is working.


九、Severe serrations when engraving or cutting.

1)If the working speed is too fast, the cutting surface of the processed material will appear serrated, and the processing speed needs to be reduced.

2)If the output is in BMP bitmap format, check whether the graphics resolution is too small. On the premise that the graphics size is correct, try to increase the resolution as much as possible.

3)Whether the synchronous belt between the laser head and the beam is too tight or too loose, adjust the tension of the synchronous belt.

4)Check the X-direction pulley, whether there is a gap due to wear, replace the pulley or belt.

5)In the stop state, check whether there is any gap between the laser head or the slider. Replace the slider or tighten the laser head.

6)Check whether the reflective lens and focusing lens are loose, and tighten the loose lens.

7)Check whether the Y-axis belt is tight or not, adjust the belt tension, and the belt tightness should not be too different


十、Water Chiller Alarm

1)If the voltage is too low, it may cause the chiller to alarm. Ensure that the required voltage is normal, and a voltage stabilizer can be used if necessary.

2)See if the water volume in the cooler reaches the standard line, if the water volume is too low, an alarm will be issued, and the pure water will be filled up.

3)Whether the water pipe is blocked or discounted, whether the water protection is blocked, the increase of water flow resistance will also cause an alarm, clean or straighten the water pipe and water protection.

4)Check whether the water pump in the chiller is normal, there is no water or the water flow is very small, replace the chiller.
