Troubleshooting Laser Marking Problems: Solutions to Common Problems from Misalignment to Blurred Marks
The company has developed a number of practical solutions to common problems such as misalignment and blurred characters.These cover calibration techniques, parameter optimization methods, and daily maintenance recommendations. They help users quickly identify problems and improve marking precision and clarity.
Why can't the laser engraving be done in the right place?
When you encounter a problem with your positioning, don't rush to adjust your parameters. First check out these areas:
Check to see if the clamp is loose.
It's just like when you take a picture and your hand shakes, the image is blurry.In particular, when using the machine continuously, it is recommended that the screws be tightened every 20 times the machine is used.
Aligning the mirrors and the work table.
The next step is to use the factory-provided calibration board to check the accuracy of the X / Y axes.If the deviation is more than 0.1mm, it is recommended that the user contact after-sales service for professional calibration.
What if the label is blurry?
Eighty percent of the time, the problem is with the focus. Try these methods:
The material's thickness was remeasured.
Don't put too much faith in the thickness of the material as it is labeled. Use a vernier caliper to measure several points.Especially with sheet metal, the actual thickness may vary by ± 0.2 mm.
Clean the lens.
If your lenses get dirty or greasy, it's like wearing dirty glasses. Remember to clean them once a week with rubbing alcohol and a special cloth.Be careful to wipe from the center outward, not back and forth.
These settings need to be carefully considered.
The speed and power of the engine are matched to the boat.
If the speed is too high, the result is like a scrawl, while if the power is too low, it's like writing with a blunt pencil.When marking stainless steel, we recommend using 80 % power at 600 mm / s, with fine-tuning to follow.
Frequency affects the degree of detail.
When carving fine logos, the frequency can be adjusted to over 50 kHz to sharpen edges.But you have to be careful, because too high a frequency can burn through thin materials. You have to experiment a few times to find the right balance.
We must remember to compensate for the environment.
Large temperature differences between summer and winter in the workshop can affect the performance of the laser. Every time the temperature changes by 10 ° C, the power has to be readjusted.When humidity exceeds 70 %, it is best to turn on a dehumidifier to prevent fogging.
