1. Small power setting, small distortion of potentiometer, optical deviation, dirty lens, focus lens inversion, focal length, laser power supply, laser tube power attenuation, high water temperature, unstable voltage, etc. Determine based on the actual situation, from simple to deep.

2. Can't connect to the device?

Whether the board driver is installed, whether the USB cable or network cable is plugged in properly, whether the USB cable or network cable is damaged, whether the adapter board is damaged, whether the board card, etc

3. Turn on the machine and move it back to the original position in the opposite direction?

The origin switch is faulty

4. Does the cutting diagram deform and overlap with the cutting?

Loose synchronous wheel screws, motor wire breakage, motor breakage, driver, voltage, etc

5. Does the device fail to start and trip when the power room air switch is turned on?

Whether the emergency stop has bounced, whether the external circuit is connected, whether the internal air switch of the device is closed, and whether a sound is heard during startup. If yes, please check the main contactor and control transformer; Water protection leakage leads to a short circuit in the laser power supply due to water ingress (such as the water protection position installed on the side, which happens to be the laser power supply), a short circuit in the water pump, and the indoor air switch being used too small, etc

6. Is the high-voltage line on fire? This problem is really a headache. I suggest placing a high-voltage insulation sleeve outside the high-voltage line

7. Is the graphic size too large or too small?

Whether the output graphic size is the same, changes in Z-axis height position, file correction, and other laser cutting y-axis third axis servo alarms.

8. Do the colors in the middle and around the image differ?

Adjust the focusing coefficient, adjust the focus of the W-axis, etc

9. Is there any damage or coarsening of the light spot during the marking process?

Dynamic, DA board, etc

10 Marking graphic position offset?

Vibration lens X-axis or Y-axis position offset, locate the center point XY axis position based on the actual offset direction

Is the XY axis of the 11 power on vibration lens swaying randomly and the dynamic motor making abnormal noise swaying randomly?

Replace the ± 12 ± switching power supply; Replace the ± 12 ± switch power supply and laser cutting machine W-axis servo alarm 320.

No light coming out of 12?

Whether the return water of the chiller is normal, the position of the W-axis changes, the laser power supply is normal, the laser tube, etc

13. Is there no display on the startup display panel?

Is the switch power supply normal, display panel, etc

14. Does the power on display panel fail to return to the original position?

Replace offline card

15. Does the shaft not feed or has weak movement?

Z-axis motor, driver, bearing, foreign object jamming and other issues

16 glass tubes do not emit light?

The light output control of glass tubes mainly includes laser tubes, laser power supplies, water circulation systems, and light output signals, including PWM light output signals provided by the board, water protection signals, door switch signals, etc. Therefore, the laser tube mainly starts from the water circulation system and optical signal of the laser power supply of the laser tube. Generally speaking, first observe whether the laser power supply is powered on normally, whether the inner and outer tubes of the laser tube are abnormal, and whether the water circulation system is normal. If there are any abnormalities, corresponding replacement or adjustment should be made. Under the normal circumstances mentioned above, the issue of optical signals should be considered. Generally, the first method to test the laser tube and laser power supply is to use a short message number (short laser power supply current of 5v and AIN short circuit water protection P and GND using an unlocked switch to control L and GND). If this method can emit light normally, it indicates that there is no fault with the laser power supply of the laser tube. It is caused by signal problems such as water protection switch, relay, door switch, and board PWM, which are eliminated in sequence. If this method does not solve the problem of the laser tube or laser power supply, it can be solved by replacing it.

Does the 17 RF laser tube not emit light?

When the laser power is turned on and the laser power is started normally, first measure whether the DC of the laser power is normal; The conduction of pins 4 and 13 of the 25-pin laser tube plug-in indicates that the water protection signal is normal, and the water protection cannot be conduction upon inspection; If the voltage of pins 7 and 20 is not pre adjusted or if the DC voltage is 4-5V at the beginning, it should be pre adjusted or if it starts to be around 1-3 V, which is a normal signal (low level conduction). If the water, power, and these two signals are normal, it can generally be determined as a laser tube malfunction. If the signal is abnormal, it indicates a board or circuit problem.

After replacing the 18 RF laser tube, did the laser tube connect incorrectly?

The problem of not being able to connect properly after restarting the cooler and equipment after connecting the plug-in (no detachment or short circuit of the internal wire), power cord (connecting the left and right negative electrodes to the ground wire), and water circuit connection is usually caused by a broken or incompatible circuit board connecting the 25-pin plug-in, such as encryption tube and non encryption tube

19 Cutting machine cutting misalignment?

(The distance after cutting the weight or collinear pattern is too large) "1.) Misalignment of feeding and cutting is caused by the step distance of the feeding shaft=measured length * original step distance/actual length (set feeding length) Second, check whether the locking pulley of the feeding shaft Timing belt and the motor Timing belt is loose. Thirdly, the loose rolling mesh and the relative sliding of the feeding shaft should be checked for any jamming Misalignment of cutting without feeding: firstly, the car motor or optical shaft synchronous wheel is loose; secondly, the phenomenon of out of step may be due to excessive processing speed, idle speed, or acceleration setting; secondly, the car motor wire may have poor contact; thirdly, the driving current may be too low; thirdly, the drive or motor may be damaged. Generally, the motor is less damaged and out of step.
