From Turning the Switch to Labeling: A Demonstration of the Entire Procedure for Adjusting a Laser

The video provides a detailed explanation of the entire process from preparing to turn on the laser to completing the marking, including setting parameters, aligning the optical path, and adjusting the marking accuracy.The hands-on demonstrations help users quickly grasp the techniques for adjusting equipment and solving common problems, thus boosting work efficiency.The book is suitable for beginners and technicians.

Preparing the equipment.

Check the power supply and cooling system.

Don't press the power button just yet! Make sure the power cord is firmly connected, particularly that the ground wire is properly connected.The cooling system (water or air) should be started in advance, to allow three or five minutes for the circulation to stabilize.Don't skimp on this step, or you'll be scrambling to deal with the alarm when the machine overheats.

Clean equipment and work surface.

He uses a lint-free cloth to wipe the lens, the track, and the work surface.If the lens has fingerprints or dust on it, the results of the engraving can be disastrous.He then checks to see if the clamp is secure, because if the material is not aligned properly it will affect the final precision.

Practical techniques for setting up parameters.

Rapid matching of basic parameters.

Don't be intimidated by the menu! First select the preset mode for the type of material (metal / plastic / ceramic). The power and speed can be left at their default values.After printing a few test images, if the lines are blurry, you can increase the power by 5 %. If the edges are burnt, you can decrease the speed. This trick will solve 80 % of the problems encountered by beginners.

Details are key to optical alignment.

He places a sheet of blank paper on the worktable, and manually adjusts the power to draw a cross.If the focus is not accurate, the lines will be uneven.Here you need to be patient: First adjust the screws of the reflector, rotating them only a quarter turn at a time, and observe the direction of change.Remember to "first make rough adjustments, then fine adjustments.

An in-depth look at laser marking accuracy.

XY-axis precision calibration.

A standard grid is used as a reference to check for deviations.When you notice that something is off, don't rush to change the software parameters! First check the belt tightness, and use your hands to push the slider and feel the resistance.Sometimes mechanical problems are more common than parameter problems. A change in the temperature in the workshop can cause the guide rails to change shape.

Optimizing depth and clarity.

To achieve a deeper, clearer mark, try "layered marking" -- divide the total power into 2-3 passes, with a half second delay between each pass to allow the material to cool.This technique is particularly effective when working with stainless steel, and also avoids the problem of the metal warping if it gets too hot.Remember to keep independent parameters for different materials and use them next time!

Common problems and emergency treatment.

What to do if the carving suddenly breaks.

If the machine stops in the middle of a job, the first thing to do is to check the coolant temperature.If it's a software problem, remember to save your current parameters before restarting.There is one trick: Every day before you turn on the computer, back up the parameters to a USB flash drive. In a pinch, that can save you.

The "sawtooth" plan.

If the lines appear fuzzy, don't panic! First check to see if the lens is loose, then test the effect at different speeds.If it is too fast, the laser will shake. If it is too slow, the laser will burn the skin too deeply.Once the threshold is set, the anti-aliasing function is activated, and the results are immediately apparent.
