Five Common Mistakes in Setting Parameters in a Laser Marking Machine

If you're just getting started with a laser marking machine, you may have already fallen into one of the common traps of parameter settings. Here are five common mistakes that beginners often make, including problems with power adjustment, speed and frequency settings, and more. Avoid these pitfalls and improve your laser marking efficiency and product quality!

In fact, too much power can be a bad thing.

Many people think that higher power means better results, but in fact, if you use maximum power on metal, you risk burning the edges, and on plastic you risk burning right through.It is recommended that users start with the 70 % power recommended by the material supplier, and gradually adjust the power level while observing the depth of the engraving.

Test-taking tips.

Test the power level: Using the same pattern, make a series of markings at different power levels, each differing from the last by 5 %. Compare the results and choose a power level that provides the best contrast without damaging the material.

Speed and frequency are mismatched.

Have you ever encountered the problem of intermittent line marking? Most likely it's because the speed is too fast but the frequency is not keeping up.It's just like writing with a pen: the faster you move your hand, the more often you have to put pen to paper.For metal engraving, the recommended speed is 800mm / s or less, and the frequency is 20 to 30 kHz.

The focus is off.

If the image is suddenly blurred, it is probably because the height of the workbench has been changed, causing the focal length to be off.Whenever you change materials or clean the work surface, make sure to use acrylic to test the position of the cutting line, and adjust the focus until the line is as thin and sharp as possible.

Wrong color parameters.

If you find that the colors in your fill areas are not uniform, don't rush to replace your equipment. Simply change the fill interval from the default 0.1 millimeter to 0.05 millimeter, and also activate the bidirectional fill function.If you are photographing a mirror-like surface, remember to select the "multiple scans" option (three scans is best).

They forget to consider environmental factors.

When the humidity exceeds 70 %, the laser tube is prone to condensation, which can lead to a decrease in energy.The studio should be kept at a constant 25 ° C, and a dehumidifier should be used to control humidity at about 50 %.Users in the north should be sure to protect their machines from the cold in the winter, and should warm the machine for 15 minutes after turning it on before using it.
