A laser engraving machine like Longer Ray5 allows you to realize many types of processing, offering not only high precision but also high-quality details for every type of DIY project. Depending on the type of material, different possibilities of laser processing may occur, including engraving, carving, and cutting. Some materials allow only some of these processes; however, some materials, such as wood, allow you to carry out all three types of processing.

If you are curious to see with your own eyes what types of processing you can achieve with your new Longer Ray5, continue reading this article, and you can find a vast archive of real photographs from the projects made by our customers with Longer Ray5.

Laser Engraving Applications

This type of processing allows you to customize everyday objects in the way you want, for example, by making a greeting card, engraving the name of your pet on its metal plate, or engraving a photograph or an image on ceramic or stone. This process is the easiest to carry out, and if you intend to engrave a difficult material such as metal or ceramics, then it is possible to temporarily color the surface in black so that the laser can engrave the material more easily and then wash off the paint at the end of the realization.

Laser Carving Applications

This type of processing causes a lowering of the surface of the material (usually wood) in a range between a few tenths of a millimeter and a few millimeters, causing a carving. This allows you to have not only a visual representation of the processing, but also feedback to the touch of the surface. Probably this is the most difficult type of processing to achieve, as it is necessary to find the right combination between the various settings of Lasergrbl / Lightburn to carve into the material without burning or cutting it. 

Laser Cutting Applications

This type of processing allows you to create three-dimensional objects and to give vent to your creativity. In fact, adapting the settings of Lasergrbl / Lightburn to each type of material (usually wood, paper, cardboard, leather, acrylic) it is easy to create a nameplate, a greeting card, a puzzle to compose and even real 3D models. Yes, just engrave and cut the various pieces of a model always using plywood of the same thickness, and then proceed manually to the interlocking of the various pieces to obtain a 3D realization. 

Access to unlimited support for image files

In physics, the propagation in space of electromagnetic field energy is called electromagnetic radiation. In particular, electromagnetic radiation with a wavelength between about 400 and 800 nm is called visible radiation and is perceptible by the human eye and transformed by the brain into visual sensations; this radiation is what is commonly called light.

In an electromagnetic wave the energy is distributed in discrete and indivisible packets, called quanta, and the quantum of energy of the visible radiation is called a photon. Photons, having energy in the form of an impulse, when they hit matter are able to excite atoms and molecules, which emit quanta at various frequencies that are also detected as heat: this is the physical mechanism at the base of life, why sunlight also produces heat, and how this heat is more or less intense depending on direct or indirect exposure to sunlight.

Although this does not exist in nature, human progress has made possible the ability to "line up" the photons of a light source, concentrating them in a light beam called a laser beam. If the propagation of a light source takes place in the form of a laser, then all the energy is concentrated within a beam of a very small section; therefore, when the laser hits matter, it is instantly able to radiate great power into a very small area, causing a sudden and rapid increase in temperature that alters the state of matter.

Laser engraving

A laser engraving machine is based on a laser module of a given power, capable of generating a laser beam that can be modulated in power within a range between 0% and 100%. When the laser beam hits a surface, it undergoes a rapid increase in temperature that instantly transforms the state of matter by combustion, and the contrast between the lasered surface and the surrounding surface creates the visual effect commonly called laser engraving.

To create an engraving, the laser module is moved in a Cartesian plane X/Y, thus being able to emit a certain power in a given spatial position, and the set of points hit by the laser beam constitute the engraving. Depending on the power with which the laser beam hits each point of the surface, it is more or less able to transform part of the matter, which results in a more or less deep incision with respect to the surface. In fact, when the laser hits a surface, not only is blackening caused by combustion but also a lowering of the surface; the higher the power of the laser, the greater the amount of matter removed. This contrast of hue and depth creates the typical effect of laser engraving, thus being able to make drawings, markings, and engravings on various types of materials.

Difference between laser engraving, carving and cutting

Depending on the type of material, different possibilities of laser processing may occur, including engraving, carving, and cutting. Some materials allow only some of these processes; however, some materials, such as wood, allow you to carry out all three types of processing.

Taking wood as an example, suppose you apply a laser beam on its surface; depending on the power of the beam, the following possibilities occur:

• The laser has a power capable of burning only the outermost layer of the surface, causing a surface blackening. This process is called laser engraving.

• The laser has a power capable of transforming the innermost layers of the material, causing a removal of matter and a lowering of the surface in a range between a few tenths of a millimeter and a few millimeters. This process is called laser carving.

• The laser has a power capable of transforming the innermost layers of the material, causing a removal of matter such that it is greater than the thickness of the material; in this way a hole is created through which light can pass, and this can also lead to the division into several parts of the original surface. Note that this can often be achieved by passing the laser beam at the same point several times so as to remove the entire thickness of the material by the sum of smaller thicknesses removed at each step. This process is called laser cutting.

Note that, even with the same material, these three processing techniques can take different settings, as they depend on the maximum power of the laser beam, the power applied to the processing, the permanence of the laser beam at each surface point (ie the processing speed), the hardness of the type of wood treated, and other factors. Therefore, it is always necessary to carry out empirical tests in order to obtain the correct processing parameters for each type of material, even if of the same type.

The processing parameters, such as power, speed, number of steps, and more, are assigned to the machine using management software such as LaserGRBL. This software takes care of processing in machine code the instructions useful for realizing by laser processing the image or the incisive effect desired by the user. In this way, the machine is able to know point by point where to apply the laser beam, with what power to apply the laser beam, and with what speed to move to a next point, thus being able to transform into reality any type of idea.

Longer Ray5 is an innovative, technological laser engraver able to offer professional performance. In fact, it is equipped with wifi technology with which it is possible to transfer work without the need for cables, the latest security systems and a 5w or 10w laser module able to offer greater performance than those offered by other laser modules of the same nominal power. Let's see together what makes Longer Ray5 one of the best products on the market.

Mainboard MKS DLC32

Longer Ray5 adopts a DLC32 mainboard, characterized by wireless technology, microSD card reading and touchscreen display with graphical interface.

• The 32bit CPU allows you to process the workload at 240mHz quickly and without delays, thus avoiding lag during laser engraving that could compromise the quality of the final result, as is the case with some 8bit mainboards. Also, it allows to reach a max speed 10.000 mm/min, great results in a short time.

• The microSD card allows you to transfer from the PC to the Ray5 the work to be carried out at the laser, thus ensuring the possibility of working at any time, even without the availability of a PC. In fact, once you have created the work file on Lasergrbl/Lightburn, just select to export the ".gcode/.nc" to the microSD card, remove the microSD card from the computer and insert it into Ray5. At this point you can start, stop, repeat and edit engraving jobs directly from the Ray5 screen, just as you would with your 3D printer, without needing a PC anymore. In addition, on the microSD card you can keep dozens of work files, so you can repeat them at any time you need them.

• The touchscreen display is equipped with an intuitive graphic interface, through which you can consult the list of working files on microSD, choose and start an incision, move the axes and fix the "homing" position, turn on and off the laser beam and establish the wireless connection between Ray5 and your wifi internet connection.

•  The wireless technology of the Ray5 DLC32 mainboard offers unique features, thanks to which it is possible to fully control every aspect of Ray5, remotely and without the need for cables. Simply establish the wireless connection between Ray5 and your wifi internet connection using the touchscreen display interface, after which make a note of the assigned IP address; at this point, by typing in the browser of your PC the IP address marked above, a web page will be opened from which you can fully control Ray5, having a "remote display" of command directly on your PC. In addition, transferring engraving jobs to microSD also becomes easier, as you can transfer files to the microSD via wifi, without the need to physically remove the microSD from Ray5.

• The mobile APP"MKSLaser" available for Android & iOS allows you to use Ray5 directly from your smartphone, not only to control the machine but also to edit   the images andthe related engraving parameters on the move.

Security Protections

Longer Ray5 adopts the latest and most advanced safety protections, so as to guarantee safe use at all times.

• Thermal protection stops the engraving work in the event that the engraved material should catch fire, alerting the user by means of an audible alarm.
• Motion protection stops engraving work in case Ray5 is suddenly bumped, preventing damage to the machine.
• Motionless protection stops engraving work if the laser module remains fixed in the same position for more than 5 seconds; this prevents the fixed laser beam in the same position from igniting the worktop.
• The eye protection at the base of the laser is made of acrylic material capable of filtering 99% of the laser beam in case it is reflected.
• Emergency General Protection can be manually activated by the user at any time should any sudden problem occur; just press the ON/OFF button on Ray5 and the machine will shut down immediately.

Updated 10w Laser Module with 0.06x0.06mm spot laser

The new version of Longer Ray5 adopts an improved 10w laser module, which offers much greater performance than competing lasers of the same power; in fact, our laser uses a new technology that allows you to reduce the amplitude of the laser beam, concentrating the laser spot in just 0.06x0.06mm (the spot laser adopted by competitors is usually 0.15x0.15mm), and by concentrating the engraving power within a smaller surface it is possible to obtain results similar to those achievable with competing lasers of greater power or with air-assist. In addition, a focal length of 50mm has been specially chosen, which is optimized for cutting. Thanks to these two technical characteristics, for example, you can cut fir wood 1.4cm thick with only 2 passages (against the 4-5 passages required by competing laser modules of the same power), or 5mm thick plywood with only 1 passage.

• We performed some demonstration tests, in order to let you see with your own eyes our tests the great performances provided by our 10w - 0.06x0.06mm - laser module. Give a look at this following table, you will be amazed!

• To compare the differences between Longer 10w - 06x0.06mm - lasermodule and our Longer 5w - 0.08x0.08mm - laser module, you can check this table.
