Longer B1 20W & 30W & 40W has a laser module that can engrave and cut various types of materials. However, depending on the type of work that is carried out, it is possible that a fair amount of smoke and wood dust is produced, which will inevitably settle on the fan of the laser module and suck into it. In fact, due to the high power of the laser beam, the laser module tends to heat up and for this reason it is necessary that there is a high-speed cooling fan; however, during its operation the fan sucks in the surrounding air and, if this is rich in smoke and dust produced during engraving, inevitably the fan and the laser module will soon be full of smoke and dust as well. When the laser module is saturated with dirt, cooling becomes ineffective, so you need to clean the laser module. 
In some cases, as a result of prolonged use, the fan may stop working, and in these cases, it is necessary to replace the fan as soon as possible, otherwise the laser module will be damaged.
To proceed with recovering or replacing the fan of the laser module of the Longer B1 20W & 30W & 40W, it is first necessary to completely disassemble the laser module from the rest of the machine. Therefore, disconnect the power cable of the laser module, then remove the connection with the air assist, and finally physically remove the laser module from the rest of the machine. Now, unscrew the 4 screws of the laser module cover and remove the cover.

After removing the metal cover, gently lift the fan, then gently disconnect its connector from the rest of the laser module, as shown in the figure.

At this point, proceed to clean the fan thoroughly.
In the event that the fan is damaged or faulty, it can be replaced with a 60mm x 60mm fan, specification 24 Volt - 0.40 Ampere, like the type shown in the figure.

After the fan cleaning or replacement procedure is complete, proceed to connect the fan connector to the rest of the laser module; Then, position the fan and proceed to close the metal cover, following the steps followed at the beginning backwards. Finally, install the laser module on the machine, carefully connect all the connectors, and carry out ignition and engraving tests, so as to verify that everything is working correctly.

Longer Ray5 is an innovative and powerful laser engraver, available in 5w, 10w, 20w and now even 30w versions. Depending on the type of laser module with which it is equipped, Longer Ray5 can perform various types of processing on various materials, but one feature is always in common, namely the absolute accuracy in the execution of the processes. 
Sometimes, however, strange effects can occur, similar to those present in the image below; in these cases, it is necessary to fine-tune your machine, so as to obtain maximum performance. 

Usually, this problem is due to a poor installation of the belts and eccentric wheels, so it is necessary to proceed with a more accurate installation. 

First, completely disconnect all the connectors of the Longer Ray5, then remove the connection cable. 

Once this is done, squeeze the belt as shown in the figure. The belt must be hard, resistant to pressure. If, on the other hand, it is soft, then it is necessary to put it under tension. 

In order to tension the belt, unscrew the T-nut as shown in the figure, then pull the belt with your hand. Keeping the strap under tension with your hand, continue to pull and simultaneously screw the T-nut tightly to secure the strap in place. 

Repeat the belt tension operation in the same way for the other side of the Longer Ray5 frame. 

Finally, make sure that the sync wheel is perfectly in line with the belt. To do this, unscrew the Sync Wheel latch as shown in the figure, then put the Sync Wheel in line and secure the latch. 

At this point, check the wheel eccentrics as well. The wheels equipped with an eccentric nut are the lower ones. With your finger, try to rotate the wheel; If but wheel slip, you need to tighten the eccentric nut of the wheel. 

Gradually tighten the eccentric nut of the wheel, gradually checking that the wheel no longer slips. Do not tighten the eccentric nut too much, but stop as soon as the wheel no longer slips. 

Do these for both the left and right sides of Longer Ray5. 

At this point, the installation has been successfully completed for the Y-axis of Longer Ray5. However, you also need to check the status of the X-axis, which is the axis that moves the laser module. 

Following the steps above, first check the X-axis belt, tightening it if necessary. After that, also check the eccentric nut of the wheel, as shown above. 

Once the tuning has been successfully completed for both the Y-axis and the X-axis, Longer Ray5 will have correctly acquired its reliability and accuracy, and therefore it will be possible to obtain precise and dimensionally correct engravings and cuts for a long time.  
Periodically, always check the belts and eccentric nuts, so as to keep the reliability of Longer Ray5 constant over time. 

Longer Camera is a really useful and functional device, capable of making spectacular video recordings of your laser engravings, and it is also fully compatible with Lightburn for complete professional functionality. Longer Camera is fully compatible with the Longer Ray5 & Longer B1 Laser Engravers, and requires only a small setup before it can be used to its full potential. 
The installation of Longer Camera is really simple, and essentially consists of two parts. The first part is about assembling and physically installing the Longer Camera, while the second part is about properly setting up the Longer Camera on Lightburn laser engraving software.
 Once the Longer Camera package has been opened, place the 4 parts on a work surface and start assembling. 

First, open the camera bracket into a cross shape. 

Once this is done, secure the bracket to the bottom mounting bracket using the hand – tightening set screws. 

At the other end of the mounting bracket, attach the camera module to the camera bracket.

Once the assembly of the Longer Camera is complete, you can proceed to install the Longer Camera on the frame of the Longer Ray5 / Longer B1. Therefore, attach the bottom mounting bracket to the frame of the RAY5 or B1 as shown in the figure. 

Finally, using a tape measure, make the distance between the working plane and the camera lens to 450mm. This distance is very important and must be accurate, as it represents the correct focus of the Longer Camera with respect to the recording plane. 

At this point, the first part of the setup has been successfully completed. Now it is necessary to proceed with the second part, concerning the correct configuration of the Longer Camera on the Lightburn laser engraving software. 

Configuring the Longer Camera on Lightburn software requires precise steps and articulated in various steps, so it is difficult to report the procedure by text. For this reason, we have made a demonstration video regarding the configuration of Lightburn, which can be followed more easily, and is available at the following link https://youtu.be/7K7Vrr1YR7Q  on our YouTube Longer channel. 

Longer Camera is available for purchase on the official Longer website, at the following link: https://www.longer3d.com/products/laser-engraver-camera-kits   

Longer B1 is an innovative and powerful laser engraver, capable of engraving and cutting multiple types of materials.

In order to avoid this phenomenon, we have decided to release an Enclosure equipped with a smoke extractor, so that the smoke can be conveyed to the outside and prevent it from spreading into the home environment.
Installing the Longer B1 Enclosure is very simple, just follow the steps below. Mounting Brackets can be divided as “Beam 1”, “Beam 2” and “Beam 3”. Please take note of this, because you need to use them as described in the next steps. 

First, connect all the various “Beam 1” with a respective “Beam 2”.

Once this is done, take 4 x "Beam 1+2" and connect them together using the appropriate corner clips, forming a square as shown in the figure.

Vertically, engage 4 x "Beam 3".

Now, connect the appropriate corner clips and form another square using 4 x "Beam 1+2" as shown in the figure.

Once this is done, take a "Beam 3" and attach a hook clip to each of its ends. Repeat this procedure 4 times.

Connect the 4 x "Beam 3 with hooks" as shown in the figure.

Connect the hook clips to the ends of 2 x "Beam 1+2", then attach them to the frame as shown below.

Attach two metal clips to the ends of the lamp. 

Connect the lamp to the structure, adjusting the distance of the two vertical "Beam 3" if necessary.

At this point, install the cover paying attention to the position of the fan outlet. 

Install the Fan brackets. 

Install the silicone rubber sheet and Fan in order outside the cover. After installed the Fan, insert another silicone rubber sheet.

Install the plastic connector, then connect the exhausted pipe. 

Congratulations, at this point the installation process has been successfully completed, and you can place the Longer B1 inside the Enclosure. 
Remember to connect the Exhaust Tube to an air intake facing outwards, so as to dissipate the fumes to the outside of your home, thus being able to enjoy a healthy and pollution-free home environment. 

Ray5 5w-10w-20w, which one is better for you?

The Longer Ray5 Laser Engravers are versatile tools that allow you to engrave and cut a wide range of materials with precision and speed; the powers currently available for Longer Ray5 are 5W, 10W and 20w (also available in 30W laser head). This comparison will explore the key differences between these three models, helping you choose the one that best suits your needs.

One of the factors to take into account is the laser power, measured in watts (W), which is important to consider when choosing a Laser Engravers, as power determines the cutting capacity and processing speed of the laser. 
a) Longer Ray5 5W is ideal for beginners and engraving projects on thin materials such as wood, metal, leather and acrylic and many more. The 5W power is sufficient for most home engravings and offers high accuracy thanks to its ultra-fine spot compression of 0.08mm x 0.08mm.
b) Longer Ray5 10W offers more power, allowing you to cut thicker materials and work faster. This module is suitable for projects that require a little more power than the 5W model, but still remains accessible for home use.
c) The Longer Ray5 20W is a more powerful model, ideal for cutting materials up to 15mm thick and for jobs that require a higher cutting speed. This laser module is perfect for advanced users and professionals who work with more resistant materials and need greater efficiency, so it is a valuable ally both in the home and in professional environments with mass production

Working speed
Working speed is another crucial aspect to consider. All three Longer Ray5 models reach a speed of 10,000 mm/min, but the power of the laser affects the actual cutting and engraving speed. The 20W model, thanks to its higher power, can complete projects faster than the 5W and 10W models, also reducing the number of passes during the cutting phase. 

Workspace
The workspace is another important feature. All three models offer a working area of around 400 x 400 mm, which means that all models are suitable for projects of similar size, but the 20W model allows you to make more use of the area as it can carry out extensive machining in less time. 

Variety of materials
Each Longer Ray5 model is designed to work with a variety of materials, but the power of the laser determines which materials can be cut and engraved more or less effectively. The 5W model is ideal for materials such as wood, metal and acrylic, while the 10W model can handle the same materials but with greater thickness when cutting. On the other hand, the 20W model increases the processing possibilities, as it is perfect for very thick and resistant materials, such as wood up to 15 mm, aluminum, glass, stainless steel, leather, and many other materials typical of the professional field.

Engraving accuracy
The accuracy of the engraving is another factor to consider. All three models offer high accuracy; in particular, the 5W model turns out to be a good compromise between quality and price, but the 10W model is particularly appreciated for its ability to emit a laser beam with an ultra-fine spot of 0.06 mm x 0.06 mm, excellent for detailed engravings. On the other hand, the 20W model, thanks to its greater power, can easily obtain engravings on tough materials such as stainless steel, and expresses its full potential during cutting operations. 

In conclusion, the choice between the Longer Ray5 5W, 10W, and 20W Laser Engravers depends on your specific needs. For a beginner, the 5W model is a good option to start this hobby. For greater power and processing speed, the 10W model is a good option and certainly the most recommended in the home. On the other hand, for more demanding jobs and thick materials, the 20W model is the ideal choice, especially for professional use.
