Causes of beam jitter at start-up of fiber laser cutting machine

Now all walks of life can use laser processing technology, the application of fiber optic fiber laser cutting machine is also more and more extensive. However, when many customers use fiber laser cutting machine, they will encounter a series of problems such as wrong start-up reset direction and beam jitter due to unfamiliar equipment or improper operation. Here is an analysis of the reasons for the jitter of the beam when the fiber laser cutting machine is turned on.

　　Causes of beam jitter at start-up of fiber laser cutting machine

　　1. Turn on and check which axis the jitter appears on, the trolley or the beam, disconnect the power supply of one axis and test whether the motor and drive of the other axis are faulty. The test can be exchanged to find out whether the problem is in the motor or the drive.

　　2. Push the cart to see if there is friction or shaking. If the gap between the sliders is too large, replace the laser slider.

　　3. When the fiber laser cutting machine is reset, the direction is correct, but when the end is reached, the trolley or beam cannot stop and hit the machine. Need to check whether the motherboard parameters are wrong. The sensor wire is broken or the sensor is damaged, and whether the magnet is in the proper position.

　　 4. Turn off the machine and push the trolley and beam by hand to see if there is resistance. If there is any obstruction, remove or tidy it up, and check if the left tension wheel is very tight.

　　 5. Check whether the timing belt, bald head, blower pipe, and drag chain are jammed.

　　6. If the reset is abnormal after replacing the driver of the fiber laser cutting machine, first check whether the parameter settings are correct, and the abnormal reset can be solved by changing the main board parameters.

　　7. Check whether the beam has a serious deviation, the left and right sides shall not be larger than 2MM, check whether the support wheels on both sides are damaged, and whether the advancement is smooth.

　　 8. For models equipped with resistance banks, resistance must be measured. If the resistance is faulty, the resistance row needs to be replaced.
