Both materials present the same feature with regard to frequency. For example, when engraving large areas on TroLase, we recommend defocusing 2mm for a consistent engraving result. If you are using a lower power laser, i.e. Just because you own a guitar, doesn't mean you're going to be Jimi Hendrix ;-) Settings are based on a 45w laser tube, adjust accordingly for other size tubes. Epilog Laser Cutters. However, there are applications in which the Air Assist is deliberately switched off. In practice, together with isotopic substitution, this means that a continuous comb of frequencies separated by around 1 cm−1 (30 GHz) can be used that extend from 880 to 1090 cm−1. CO2 lasers are the best suited for soft tissue procedures in human and animal specialties, as compared to other laser wavelengths. Just wondering if anyone has a suggestion for what my laser frequency or settings should be for this material. Speed 4. The greater the marking speed, the higher the required frequency setting. The four most important settings of a laser cutter are power, speed, frequency and for focus distance. [15], The common plastic poly (methyl methacrylate) (PMMA) absorbs IR light in the 2.8–25 μm wavelength band, so CO2 lasers have been used in recent years for fabricating microfluidic devices from it, with channel widths of a few hundred micrometers.[16]. Minimum Watts required for Fiber or CO2 Laser Our products are a perfect solution to mark on a variety of different substrates with a CO2 or Fiber laser/Yag laser. Because the laser transitions are actually on vibration-rotation bands of a linear triatomic molecule, the rotational structure of the P and R bands can be selected by a tuning element in the laser cavity. I'm now familiarizing myself with many different materials and attempting to test and document the best settings for quality. Find out more about laser cutting at www.LaserXYZ.com. AMADA's 3kW ENSIS fiber laser technology utilizes a highly innovative resonator to automatically and precisel… Choose settings that give a durable mark without overpowering or damaging the object. Therefore, for […] [3]. The frequency setting controls how many laser pulses are applied to the piece you're cutting, every inch. The population inversion in the laser is achieved by the following sequence: electron impact excites the {v1(1)} quantum vibrational modes of nitrogen. That means it will only output 50 watts over a period of time. Setting the frequency at a low value (50 to 100) will produce a perforation. CO2 lasers have always been very effective for acne and other scars and the fractional CO2 is no exception. Some of the main influencing factors of a good laser cut are listed below. [3], The CO2 laser can be constructed to have continuous wave (CW) powers between milliwatts (mW) and hundreds of kilowatts (kW). Laser beam welding (LBW) is a welding technique used to join pieces of metal or thermoplastics through the use of a laser.The beam provides a concentrated heat source, allowing for narrow, deep welds and high welding rates. A great example of this technology used on a white MacBook is on the following link to the Epilog's website. This parameter is used to adjust the laser output frequency by directly operating the Q-switch. The only solution (so far) to engrave this material is to use a YAG/Fiber laser. Ahigher chosen speed (e.g. Login or register to add settings . Please visit http://www.DIY3DTech.com for more information on this and many other projects! If you have other settings you’d like to suggest, please send an email to design_help@ncsu.edu with the details. Resolution is only one factor i Email Subscribers. Power settings that are too high can melt and distort many materials. Several Mark Setting Objects may be used in a marking sequence especially if marking Single Line and True Type fonts with Shape or Vector Drawing objects in the same layout each type of marking object generally needs different laser settings to get the best performance. For example, this approach is appropriate for a relief engraving. Because the excitation energy of molecular vibrational and rotational mode quantum states are low, the photons emitted due to transition between these quantum states have comparatively lower energy, and longer wavelength, than visible and near-infrared light. Usually, for a CO2 laser, the value can be set within a rough range of 1,000 to 60,000 Hz. Furthermore, Air Assist protects the lens from damage, as it stops dust from adhering to it in the first place. Gas 5. Polycarbonate is a poor choice for laser cutting. Power settings that are too high can melt and distort many materials. Historically, lenses and windows were made out of salt (either sodium chloride or potassium chloride). For dark wood engravings or stamp engravings, you generally need high power, whereas low values are used for materials such as paper. Thanks in advance! The frequency of the laser affects the channel size. Fusion cutting is another standard process used in metal cutting, and it can also be used to cut other fusible materials, such as ceramics.. The Pass parameter determines the number of engraving or cutting passes. Lasers rely on differing techniques to produce thermal damage to the epidermis and dermis, result… The CO2 then radiatively emits at either 10.6 μm[i] by dropping to the {v1(1)} (symmetric-stretch) vibrational mode, or 9.6 μm[i] by dropping to the {v20(2)} (bending) vibrational mode. Diamond windows are extremely expensive, but their high thermal conductivity and hardness make them useful in high-power applications and in dirty environments. 3 - Frequency vs Hatch Grid 4 - Setup Squares for Distortion (PDF) 5 - EzCad Manual (PDF) If you want to contribute to this site, please add your fiber laser settings. These instructions show a sub-$100 laser power meter probe at work, taking quick laser power measuremen… For a CO2 laser, the value can be set within a range of 1,000 to 60,000 Hz. 25 or 30 watts, and are having trouble marking certain substrates, here is another tip. If you have an RF Excited tube, this setting allows you to control the PWM frequency of the pulses sent to the laser, and can change the edge finish on certain materials. 's Blade RF Self Refilling is not only a radio frequency CO2 laser source, engineered for mid-power applications on plastic, wood, leather and other materials.It's engineered … Typically, the mirrors are silvered, while windows and lenses are made of either germanium or zinc selenide. During the cutting process, the Frequency parameter is recognised and displayed to you in Hz (Hertz). These settings are designed to help guide the user to the optimum parameters as quickly as possible. From #34 (comment).. Add a '$' setting to allow different laser PWM frequencies. While the material was inexpensive, the lenses and windows degraded slowly with exposure to atmospheric moisture. A great example of this technology used on a white MacBook is on the following link to the Epilog's website. I recently bought a 50W laser cutter and have been struggling to cut through 1/4inch plywood. For a CO 2 laser, the value can be set within a range of 1,000 to 60,000 Hz. SAFETY IS MOST IMPORTANT. Laser cutting operating costs can be estimated as cutting per hour or per unit length. - 191 - APPENDIX B: MATERIAL SETTINGS Fusion Series Suggested Material Settings (CO2) • These are only suggestions: Every type of material will react differently with the laser, even from one plastic to the next. The science of Diode Lasers. Will likely implement this as value with the current $32 laser mode setting, such that 1, 2, or 3 would indicate different frequencies.. CO2 lasers can be made to emit from 8.98 to 10.2 μm by selecting the appropriate gas. The Q-switch is an electro-optical system, which controls the opacity of a lens making it possible to change the laser beam frequency. Here is a brief explanation. With some materials, for example, it can be advantageous to engrave with lower power and high speed, and then repeat this process several times. The frequency settings in Hey Folks, I'm a long time lurker but haven't posted much here. Depends on different materials and the marking effects you want so for a new operator may need conduct dozens of trials to know the ideal marking parameters for each material and even some experienced engineers […] The increase in collagen production and the creation of new skin cells in the channels significantly reduces the appearance of dark spots caused by melasma. This setting also affects the quality of the laser cut. In this case, the lens must be checked for contamination more frequently than with Air Assist. In flow-through lasers, a continuous stream of CO2 and nitrogen is excited by the plasma discharge and the hot gas mixture is exhausted from the resonator by pumps. Email adress Password. Incorporating fiber laser cutting technology helps users process a variety of tubing and pipe with greater speeds compared to a CO2 system. They can be set as a percentage between 0 and 100%. Prisms are not practical as tuning elements because most media that transmit in the mid-infrared absorb or scatter some of the light, so the frequency tuning element is almost always a diffraction grating. Material PreparationBy managing these variables, we are able to ensure perfect, reliable and repeatable laser cuts of our acrylic material. Speed is how quickly or slowly the laser nozzle will move around in the X and Y directions. For example, if you want to achieve a smooth edge when cutting acrylic, you need higher temperatures and thus this value is set to at least 5,000 to 20,000 Hz. Have you ever wondered what that frequency setting does on your laser? laser files in a variety of software, such as AutoCAD, and print the file directly to the laser All system configurations and settings are set in the print driver, including engraving resolution, frequency, focus, speed, power and more We find this provides users with the easiest-to … By rotating the diffraction grating, a particular rotational line of the vibrational transition can be selected. Marking laser stations with galvo marking heads. Using nitrogen or argon gas as cutting gas … If you have an RF Excited tube, this setting allows you to control the PWM frequency of the pulses sent to the laser, and can change the edge finish on certain materials. It specifies the number of laser pulses per second. Because the atmosphere is quite transparent to infrared light, CO2 lasers are also used for military rangefinding using LIDAR techniques. How To Laser CO2 Marking, Other, Tutorials How To Laser Cut Acrylic. Recommended Power Settings for Material Test. ... now we can use the board of k40 in 80 watts co2 laser power supply, it can trigger the max power of supply and tube? Reply Delete. For example, if you want to achieve a smooth edge when cutting acrylic, you need higher temperatures and thus this value is set to at least 5,000 to 20,000 Hz. See reference table for details. This latter frequency was subsequently measured by Evenson et al. Laser Source: CO2 laser, 30-120 watts; Work Area: 16" x 12" (406 x 305 mm) up to 40" x 28" (1016 x 711 mm) Max. For high power applications, gold mirrors and zinc selenide windows and lenses are preferred. And finally, from the "100W Co2 Laser Tube Operation Instruction": It is not proposed to control laser power with high-frequency modulation, because it will have impact on the service life of the laser. Frequency depends completely on the material used. During the cutting process, the Frequency parameter is decisive and is given in Hz (=Hertz). A lower frequency will generate ‘spotted’ engraving while a higher frequency will allow … Optical elements made of diamond can even be sand blasted without losing their optical properties. To achieve a good result, this should be the same or a multiple of the dpi selected in the print setting. 100%) and lower frequency (e.g. The power and speed laser parameters are the most important settings in the material database. This means that the material is less stressed per pass. It was invented by Kumar Patel of Bell Labs in 1964,[1] and is still one of the most useful. Less time = less cost. Material Test Settings (based on 45w laser tube, vector speeds for … There are also diamond windows and lenses in use. Laser cutting and marking is a skill you must develop. Our general recommendation is 25-30 watts minimum for a CO2 laser and 10 watt minimum for a Fiber Laser. The 10.6 μm CO2 laser remains the best surgical laser for the soft tissue where both cutting and hemostasis are achieved photo-thermally (radiantly). Sadly the wavelength from CO2 Lasers make it really difficult and almost impossible to engrave on polycarbonate. Laser Source: CO2 laser, 30-120 watts; Work Area: 16" x 12" (406 x 305 mm) up to 40" x 28" (1016 x 711 mm) Max. RF lasers can run 500-800mm/sec. For example, if you want to achieve a smooth edge when cutting acrylic, you need higher temperatures and thus this value is set to at least 5,000 to 20,000 Hz. Taking the fiber laser out of focus by +.03” - .09” broadens the beam and produces a very bright mark on anodized coating. If the z-offset is set to zero, it works "in focus," meaning the focus is exactly on the material surface. The filling gas within the discharge tube consists of around 10–20% carbon dioxide (CO2), around 10–20% nitrogen (N2), a few percent hydrogen (H2) and/or xenon (Xe) (usually only used in a sealed tube), and the remainder of the gas mixture helium (He). Obviously the faster it moves, the less time it will take for your project to complete. Midrange values are use to reduce over burn when cutting, and high values are often used when more heat is desired to melt the sides when cutting acrylic. Diode Lasers. A setting above 30 mA will, in almost all cases, greatly diminish the operational life (changing an expected life of several years to months). CO2 lasers can be used to remove vocal fold lesions,[9] such as vocal fold cysts. IF YOU DO IT WRONG THEN YOU CAN BE ELECTROCUTED. There is no point in setting a PWM pulse duration less than the lasers ability to respond! According to the American Society for Aesthetic Plastic Surgery, there has been a 270% increase in laser skin resurfacing procedures over the past decade.1This increase is likely the result of patients seeking facial rejuvenation without the high risk and recovery time associated with standard surgical procedures. Frequency: 1% Focus: +.06 to +07 The contrast / brightness of marks achievable on the fiber laser are excellent and can often be much brighter than marks from a C02 laser. Laser cutters are amazing tools. Table Setup 2. It specifies the number of laser pulses per second. We have summarized some tips & tricks for you. These lasers are primarily used for metal cutting, though you will see CO2 laser energy as low as 150 watts for cutting thin metals. Researchers in Israel are experimenting with using CO2 lasers to weld human tissue, as an alternative to traditional sutures.[10]. Also available is a laser cutter user guide.. Type of Acrylic 3. I do understand differences in lasing process (somewhat) by now… 3 months digging in the “books” waiting for my machine to arrive… The active laser medium (laser gain/amplification medium) is a gas discharge which is air- or water-cooled, depending on the power being applied. When using CerMark Metal Marking Solution , remember that not all metals use the same speed setting. [7] It is also used in the additive manufacturing process of Selective laser sintering (SLS). The finest frequency selection may also be obtained through the use of an etalon. Login. The frequency range is 1 to 5000. The process is frequently used in high volume applications using automation, as in the automotive … The active laser medium (laser gain/amplification medium) is a gas discharge which is air- or water-cooled, depending on the power being applied. Some examples of medical uses are laser surgery and skin resurfacing ("laser facelifts", which essentially consist of vaporizing the skin to promote collagen formation). Fig.1 The laser beam melts the workpiece while the cutting gas blows away the molten material and slag in the incision. [8] CO2 lasers may be used to treat certain skin conditions such as hirsuties papillaris genitalis by removing bumps or podules. The type of laser being used is the primary consideration and the settings between a solid state laser and a CO2 will be entirely different. ABS Emits cyanide gas and tends to melt ABS does not cut well in a laser cutter. The CO2 laser produces a beam of infrared light with the principal wavelength bands centering on 9.6 and 10.6 micrometers (μm). On the other hand, when cutting wood a low frequency of 1000 Hz is necessary in order to achieve, for example, the brightest possible cutting edge. When engraving TroLase engraving materials, for example, a more attractive engraving result is achieved without Air Assist. In this example, settings around 100% power and 30-60% speed should be optimal. There are a whole host of materials that a CO2 laser cutter can cut, etch or mark – but some – due to the material surface reflection – just won’t work (aluminum is an example). Let's say you have a 50 watt CO2 laser. Higher laser resolution equates to finer detail in your engraving. The table below shows the output range for nine possible isotope combinations:[2]. A laser’s wattage, the type of optics, the quality of the beam, the spot size, and even the software used will affect the mark quality you will achieve with a given power setting. AMADA engineered the 3kW ENSIS 3015 RI to include an innovative Rotary Index with the power and speed to efficiently transition from flat sheet to tube or pipe cutting. closer to the material) up to 127 mm (table moves down, i.e. [2] who related the frequencies of R(10) and R(12) lines of the 0001 - 0200 band of C02 to the frequency of the 28 4m water vapor laser line. The Mark Settings Object is used to change the laser settings within the marking sequence. The CO2 laser has the longest wavelength of all the lasers on the market and can be used safely on darker skin types with appropriate adjustments in the settings. Marking area up to 44.1 x 25.0 inch. Frequency (Hz, PPI): The frequency parameter specifies the number of laser pulses per second. To be kept up to date about new blog posts, please subscribe to our email newsletter. Settings need to be modified from those typically used for acrylic. How to Test and Set a Chinese (China) Made CO2 Laser Power Supply to Get Long Life From Your CO2 Laser Tube for Your Laser Engraving and Laser Cutting Machine System: Be safe when performing this project. Laser Parameters 1. In modern industrial production, laser cutting is more widely used in sheet metal, plastics, glass, ceramics, semiconductors and materials such as textiles, wood and paper. Also, keep the power setting as low as possible. further away from the material). Carbon dioxide lasers are the highest-power continuous wave lasers that are currently available. In marking metal and plastic,There is a setting parameter range for reference to test ,Speed 100-2000 adjustable,Power 30-80 adjustable,Frequency 5-30. At the same speed and power settings, any rise in the frequency ends up with a reduction in the channel size. The following are suggested laser cutter configuration settings for various materials. Amplification. This varies from material to material and is also dependent on the specific settings of the laser. How can I quickly and easily determine the optimal laser parameters for my material? Melt Cutting. Get All the Facts About Fractional CO2 Laser Treatments The 9–12 μm wavelength of CO2 lasers is useful because it falls into an important window for atmospheric transmission (up to 80% atmospheric transmission at this wavelength), and because many natural and synthetic materials have strong characteristic absorption in this range.[2]. Having less variables will help to find the optimum settings faster. The resulting hot helium atoms must be cooled in order to sustain the ability to produce a population inversion in the carbon dioxide molecules. Some parts cut no problem, others not at all. Taking the fiber laser out of focus by +.06” - .09” broadens the beam and produces a very bright mark on anodized coating. Lower frequency and higher … I've recently installed a G Weike LC1390 machine with a 130/150W Reci W6. Power 2. [11][12][13][14] CO2 lasers can be used in place of a scalpel for most procedures, and are even used in places a scalpel would not be used, in delicate areas where mechanical trauma could damage the surgical site. If even and odd lines do not dance and lines are aligned horizontally - then everything is fine. Lasers were first used for cutting in the 1970s. We recommend a minimum of 30W of power for CO2 lasers, and 10W of power for solid state lasers. Settings are 100% Speed, 50% Power, 150Hz Frequency. Full Spectrum Laser 6216 S Sandhill Rd Las Vegas, NV 89120 702-802-3100 Irrelevant to me, hence filtered out. With our CO2 laser engravers and laser cutters, you can cut and engrave on wood, fabric, acrylic. Sadly the wavelength from CO2 Lasers make it really difficult and almost impossible to engrave on polycarbonate. This is the frequency of light t he laser cutter uses to cut materials, so it is very ineffective at cutting polycarbonate. Material Height: 4.5" … THE HIGH VOLTAGE AND POWER COMBINATION CAN BE LETHAL. Thunderlaser is a leading manufacturer of laser systems. The exact wavelength depends upon the isotopic composition of the, "Continuous-Wave Laser Action on Vibrational-Rotational Transitions of CO, "Carbon-Based Curtain Absorbs Stray Laser Light", Journal of Micromechanics and Microengineering, "Israeli researchers pioneer laser treatment for sealing wounds", "Mechanisms of pulsed laser ablation of biological tissues", "Oral soft tissue laser ablative and coagulative efficiencies spectra", "Laser Surgery Basics - American Laser Study Club", https://en.wikipedia.org/w/index.php?title=Carbon_dioxide_laser&oldid=997380985, Articles with unsourced statements from December 2015, Creative Commons Attribution-ShareAlike License, This page was last edited on 31 December 2020, at 06:23. Optimal laser parameters for laser engraving and laser cutting for CO2 laser applications. Applications include gynecology, dentistry, oral and maxillofacial surgery, and many others. Studies have shown that compared with other types of lasers and treatment modalities, Physicians using CO 2 lasers for ear surgery can attain superior outcomes (1,2,3).. Brand of Acrylic 2. Because of the high power levels available (combined with reasonable cost for the laser), CO2 lasers are frequently used in industrial applications for cutting and welding, while lower power level lasers are used for engraving. Freilingerstr. In sealed lasers, this takes place as the helium atoms strike the walls of the laser discharge tube. Exhaust 4. A "high" cutting speed is 10%. Subscribe to our newsletter and stay up to date. Advantages include less bleeding, shorter surgery time, less risk of infection, and less post-op swelling. We'll do this before we run our main project file so that we can optimize for the… Need to research how PWM frequencies effect lasers and whether or not this is even required. The carbon dioxide molecules then transition to their {v20(0)} vibrational mode ground state from {v1(1)} or {v20(2)} by collision with cold helium atoms, thus maintaining population inversion. If the engraving area is small, the laser may not have sufficient distance to get up to the full speed, so you may need to reduce the power slightly if you want a shallower engraving on small jobs. In the next few years, the application of laser cutting in precision machining and micro-machining will also gain substantial growth. [citation needed] The specific proportions vary according to the particular laser. Frequency 3. Register new account. Sheet made from Eastman Spectar™ copolyester can be laser cut. For a CO 2 laser, the value can be set within a range of 1,000 to 60,000 Hz. The example below explains the relationship between frequency and speed. RF CO2 | 350-550-750-850 W | 10.6 µm | Self-Refilling Blade RF Self-Refilling (350W - 850W) El.En. While other materials can be extremely hazardous to either humans or the machine itself (like PVC and ABS). Epilog's high-speed CO2 laser machines come in a variety of configuations to fit your budget and application processing needs. 5 when inspected from left to right in each line of subfigures. 994614 Marchtrenk, Austria. SP series: CO2 laser cutter for large-format materials. The hard-tissue is ablated at temperatures as high as 5,000 °C, producing bright thermal radiation. It specifies the number of laser pulses per second. 20 kHz) cause a “perforation." Frequency: 1% Focus: .05” The contrast / brightness of marks achievable on the fiber laser are excellent and can often be much brighter than marks from a C02 laser. The more power, the darker and deeper your engravings will be and the … Higher power is needed … Laser Cutting thin leather hearts with the Epilog Zing 30W CO2 Laser Cutter. Otherwise, go to next step fot settings. Because nitrogen is a homonuclear molecule, it cannot lose this energy by photon emission, and its excited vibrational modes are therefore metastable and relatively long-lived. Here is short video that shows you. Note that cutting and engraving speeds are not comparable. So if you turn the laser on, with a high frequency (5000 rate, 1000 ppi) that turns the laser on CW (Continuous Wave), then you will get pulses that turn on and give you 50 watts. This specifies the number of laser pulses per second. Carbon dioxide lasers have become useful in surgical procedures because water (which makes up most biological tissue) absorbs this frequency of light very well. The first frequency measurement in the 10 m region was reported by Daneu et al. This means that the laser source is not pulsing quickly enough to mark a continuous line. I dismiss any info i find on fiber or RF lasers. However, there are also applications in which deliberate defocusing is desired. The width of laser cut or kerf, quality of the cut edges and the operating cost are affected by laser power, cutting speed, assist gas pressure, nozzle diameter and focus point position as well as the work-piece material. The Speed laser parameter describes the movement of the laser head. If you set this parameter to "Auto," JobControl automatically determines the optimal resolution of the laser pulses. For example, large-scale engravings of TroLase materials are engraved at high speeds between 80 and 100%, but for photo engravings with lots of detail on wood, the speed should not exceed 10%. Power is how powerfully the laser fires regardless of speed. Look at the square with a magnifying glass. Fractional CO2 lasers excel at treating deeper wrinkles, more severe textural changes from sun damage, wrinkles, blotchiness, acne scars, and surgical … A guide for engraving speeds is between 500-600mm/sec for DC lasers. The Soviet Polyus was designed to use a megawatt carbon-dioxide laser as an in-orbit weapon to destroy SDI satellites. I have a Full Spectrum Laser 12x20 Hobby Series CO2 45 watt. The only solution (so far) to engrave this material is to use a YAG/Fiber laser. Feel free to consult our "Choosing a Laser section for more information". Laser wavelength can be tuned by altering the isotopic ratio of the carbon and oxygen atoms comprising the CO2 molecules in the discharge tube. With the exception of the Zing Starter Series, which goes up to 1000 DPI, the rest of Epilog's product line can engrave at resolutions up to 1200 DPI. Test Your Material to Determine Laser Speed and Power Settings: In this Instructable we will use a test file to find out how the laser works with your material when it is cutting and engraving at different speed and power settings. Laser Settings for LMM14 Materials The following table details recommended laser settings for LMM14 materials on a range of common substrates. I am confident its not an alignment or laser tube problem. Epilog's high-speed CO2 laser machines come in a variety of configuations to fit your budget and application processing needs. Override PPI Only available on Trocen controllers, the PPI setting (Pulses Per Inch) lets you tell the laser to send an exact number of pulses per inch of travel, instead … Laser Process Setup 1. N2{v1(1)} and CO2{v3(1)} being nearly perfectly resonant (total molecular energy differential is within 3 cm−1 when accounting for N2 anharmonicity, centrifugal distortion and vibro-rotational interaction, which is more than made up for by the Maxwell speed distribution of translational-mode energy), N2 collisionally de-excites by transferring its vibrational mode energy to the CO2 molecule, causing the carbon dioxide to excite to its {v3(1)} (asymmetric stretch) vibrational mode quantum state. What do these parameters such as power, speed, ppi, Hz, pass, Air Assist, z-offset actually mean? Lower CO2 wattage will have an effect on metal similar to the light from a flashlight bouncing off of a mirror. PWM frequency: The inverse of PwmPeriod is the PWM frequency. Level 2 is actually a pair of levels close together, which is why there are 2 separate frequency bands that a CO2 laser can operate on, centred around 9.4 um and 10.4 um (i.e., just above and just below 30 THz). For example, a higher power laser can deliver more energy than a lower power laser; a smaller spot size can produce a stronger spot of power. Depends on different materials and the marking effects you want so for a new operator may need conduct dozens of trials to know the ideal marking parameters … It remains to be seen if it is as effective as the traditional CO2. Basically, cutting is slower than engraving. The PPI parameter (=pulses per inch) determines how many laser pulses per inch are used for the engraving.
