INTRODUCTION

Longer B1 30W & 40W has a laser module capable of engraving and cutting multiple types of materials. However, depending on the type of work that is carried out, it is possible that a fair amount of smoke is produced, which can inevitably settle on the lens of the laser module and therefore blur it. Once the lens of the laser module is dirty or clouded, the laser beam can no longer pass through it and therefore the emission of the laser module is drastically reduced. As a consequence, more and more power will be needed to engrave the same materials already engraved previously, until it will be practically impossible to engrave any type of material even setting 100% power. This problem occurs most when an air assist system is installed but not enabled; In fact, an Air Assist system allows you to create air pressure in the vicinity of the lens, thus preventing smoke and dust from settling easily on the lens.

In order to solve this problem, it is necessary to proceed to cleaning the lens of the laser module; Once the lens is cleaned, the laser beam can pass through it without suffering losses and therefore the materials will be engraved or cut again to perfection.

To proceed with the cleaning of the lens of the laser module of Longer B1 30W & 40W it is necessary first to completely disassemble the laser module. After separating the laser module from the rest of the machine, remove the four screws shown in the figure:

Once the four screws have been removed, the protective shield will be removed from the laser module, which will appear as shown in the figure. At this point, to remove the air assist nozzle, unscrew the small screw located on the side of the nozzle.

The laser module of the Longer B1 30W & 40W has a factory-installed protective lens, which can be unscrewed and cleaned separately from the laser module. This lens is a simple protective glass, and has no focusing function, for this reason it can be removed and cleaned/replaced. After removing the protective lens, you can proceed to clean the lens with the use of a cotton swab soaked in alcohol. Be careful to prevent alcohol from entering the inside of the lens.

Conclusion

Use one or more cotton swabs soaked in alcohol, until the lens is completely clean and free of dirt; at this point, therefore, you can proceed to screw it to the laser module and reassemble the laser module of Longer B1 30W & 40W. At the end of the cleaning procedure, you can proceed to engrave a sample file contained in the microSD card of Longer B1 30W & 40W, so you can evaluate the total restoration of the functionality of the laser module. If the lens is too much dirty and cannot be cleaned, you can contact us for buying a replacement spare part. In order to keep the lens always clean, remember to keep enabled the air assist, this will help the engraving quality.
