New Users 'Guide: How to Calibrate a Laser Marking Machine

The alignment of the galvanometer mirrors is a critical step in ensuring the precision of laser marking.It provides a detailed explanation of the practical steps involved in mirror calibration, including preparatory work, the specific steps in the calibration process, and handling common problems. It is suitable for new users to quickly master the technique of laser marking machine mirror calibration and to improve equipment usage efficiency.

Why is the calibration of the galvanometer mirror so important?

The mirrors in a laser marking machine are like its "eyes." If they are not aligned properly, the markings it produces may be distorted or even completely off target.In particular, beginners who have just started using the equipment often overlook this step and waste materials.Don ’ t worry, we ’ ll show you step by step how to calibrate the galvanometers.

Preparations for calibration.

Check the status of the equipment.

First, turn on the laser marker and preheat it for 10-15 minutes, to allow the galvanometer and laser to stabilize.This step cannot be neglected if the equipment has just been moved or has been unused for a long time.

Prepare the calibration tools.

Find a smooth piece of white paper or a special calibration board, and prepare a ruler and a marker.If conditions permit, it would be more convenient to use the calibration software offered by the manufacturer.

Start calibrating the mirror.

Step one: Test graphic.

Open the laser engraving software, choose a simple cross or square, set the power to a low level (e.g. 10 %), and engrave the pattern on the prepared white paper.At this point, it is important to check whether the pattern has deformed or shifted.

Step 2: Adjusting the mirror offset.

If you find that your image is not centered or your lines are not straight, enter the "galvanometer calibration" module.First adjust the X and Y axis offset parameters and then repeat the marking test after each fine adjustment until the pattern is completely aligned.

Step three: Check the focus.

The depth of the engraving is then tested.If the edges are blurred, it could be that the mirror is dirty or the focus is not correctly adjusted. Remember to clean the mirror with a lint-free cloth, and re-adjust the focus.

Don't forget these details after calibrating.

After calibration is completed, save the parameters! Many new users turn off the software after calibration, only to have to start all over again the next time they turn on the computer.In addition, it is suggested that a simple calibration be performed once a month, especially after high frequency use, as the mirror is susceptible to temperature and vibration.

Don't panic when you run into problems.

If the laser still doesn't hit the target after calibration, check first to see if the lens is loose or if the laser head is level.If you just can't seem to get it right, when you contact the manufacturer's technical support department, remember to take a picture of the marking result and a screenshot of the parameters; this will help the tech guy pinpoint the problem more quickly.
