Laser drive system: Which one to choose?-Bunny

In this week’s blog, we talk about the differences of the laser drive system in cutting and engraving machines. Namely the gantry system and the galvanometric system. Find out which ones are best for your type of work.

Gantry / Cartesian system

Gantry laser systems, common in CO² gas machines, base on XY motions, moving the laser above the material to be cut or engraved. This system best use for large format applications (600mm or larger) when cutting thicker material substrates. The laser move along the XY axes to the area set for the action.

Galvanometric system

Already the galvanometric laser movement system, the technology base on moving mirrors, similar to those used to create light shows. Mirrors make small angle adjustments to move the stationary laser beam in different directions within a specific cutting or engraving area.

Cutmaker offers a wide range of machines including CO² laser and fiber optic technologies. Enabling you to choose not only the best positioning method but the best type of laser beam. The advantage of the galvo system is the speed. The galvo system can be up to 10 times faster than a gantry system. However, it has a lower desktop limit compared to the gantry system.

Contact one of our vendors to find out which laser engraving cutting machine is ideal for your work, gantry or galvanometric.

CO2 glass laser tubes vs. metallic-Bunny

If you want to buy a CO2 laser machine, you must consider three factors. One of the main attributes that distinguishes the systems that are on the market is the laser tube that the machine uses as a type of laser. The two main options you will find water cooled glass tubes and air cooled metal tubes.

Glass laser tubes

Water-cooled glass tubes are usually a tempting option, mainly because of their low cost. The glass tubes themselves are less expensive and the laser is produced by the excitation of the gas with direct current (DC), which constitutes a relatively economical process. In addition, glass tubes produce good quality rays that work properly for laser cutting. However, glass laser tubes have a number of disadvantages.

Almost everyone needs to be cooled by water. Glass is a bad conductor of electricity, so water circulation is required to remove heat. Without a water cooling system, the glass laser tube would overheat and stop working. This cooling system increases costs and space, in addition to adding more points of failure that need maintenance.

The need for a water cooling system also presents some considerable safety problems. The DC power supplies that excite the CO2 gas in a glass laser tube need to operate at very high voltages. When those voltage levels combine with a water cooling system, the results can be lethal if something goes wrong.

The DC excitation process inherently limits the pulse rate of the laser tube. When a laser is recording, it does not heat continuously, but generates pulses as it moves through the material, heating many times per second. DC-excited laser tubes generate pulses less frequently, which significantly decreases the speed and quality of engraving.

The lifespan of the laser tubes excited by CC is also an issue that should consider. Glass is naturally more fragile than metal, therefore the risk of damage during shipping and installation is greater. The main concern associated with glass tubes is that the DC excitation process bombards the optics and electrodes of the tube with ions, which increases the chances of deterioration over time. Most glass tubes only guarante for six months. And when a glass laser tube fails outside that period, you should generally buy a new one, increasing costs and waste.

Metal laser tubes

The only disadvantage of metal laser tubes their high cost. However, this cost allows you to be calm in terms of performance, duration, safety and size.

The metal and ceramic CO2 laser tubes cool by air and the gas excite by alternating current of radio frequency (RF). The temperature properly regulate through fans integrated in the machines. This not only reduces the space used, but eliminates the need (and cost) to have additional equipment and limits the amount of items that require maintenance. In addition, it avoids the safety concerns of water cooling in conjunction with high voltages.

The RF excitation process generates faster laser pulses, resulting in higher engraving speed and more delicate product details. Metal pipes are also more durable than their glass counterparts.

Build machines with air-cooled metal and ceramic CO2 laser tubes to ensure that customers receive the highest performance systems possible. All our tubes back by a two-year warranty that minimizes discomfort in the strange case of a problem. If this happens, our metal laser tubes can often repaire instead of replaced.

With glass laser tubes, you can achieve a good quality laser cut for a low price. With the metal laser tubes you get the highest quality laser cutting and engraving, along with the confidence that the laser will last much longer, engrave faster and be much safer.

Each situation and budget is unique, and it is important to investigate which laser machine. And which laser tube are the best option for you and your company.

Is the dual source laser equipment the right equipment for you?-Bunny

In the laser market, you will notice that there has been a large increase in the number of dual source laser system options. The reason? The demand exists! It is very attractive to have more options with a single laser system. The reason? The demand exists! It is very attractive to have more options with a single laser system. With the dual source system, you can choose the best laser source for your application, easily and quickly.

For people who have just started with laser systems, the double source systems we are referring to include both CO2 and fiber laser sources in a single system. The CO2 laser system has a very versatile laser frequency and works well with wood, acrylic, plastic, glass, marble and much more. However, what CO2 systems do not do is to engrave in-depth metals, which is where the additional feature of fiber laser source comes into play. Depending on the system, you can exchange sources or operate them alternately; You should only select when you want to use each of the sources.

The benefit of a double laser source system is its versatility. But in what other situations would a dual source system be the right choice for your application?

1. Do you plan on mainly using only one source?

Will the CO2 laser operate 85% of the time since it only occasionally needs the fiber laser? So the double source is a good way to add additional material processing capabilities without adding a second equipment to the floor of your workshop.

It is important to remember that you can only use one laser source at the same time in the dual source system, so you will not be able to run CO2 and fiber jobs simultaneously. If you plan to have both the CO2 laser systems occupied and 100% of the time, then it may be a better option for you to purchase a CO2 system and a fiber system independently.

2. Do you have a limited amount of space?

If you have limited space on the floor of the workshop, a double source system can be a very attractive option. If you only have space for one team, then a dual source system is an excellent way to maximize the capabilities of your machinery without the need to expand your physical work space.

3. Does your product contain both metal and other material?

Do you have a product that contains both metallic and wooden areas that you would like to customize? Or plastic and steel? And chrome and leather? Then a dual source system may be the right option for your application. A dual source system allows you to record with both the CO2 laser (wood, acrylic, leather, etc.) and with the fiber (metal) laser in a single job sent to the laser system.

So, now you can better decide if a dual source system is right for you. When you start the purchase process having asked the right questions, you will be better prepared to decide if a double source system or two independent CO2 and fiber laser systems are suitable for your situation.

Five tips to maximize your laser production-Bunny

One of the best things about laser cutting and engraving systems is how quickly. They are able to engrave a pattern or cut the most intricate designs. However, operators are always looking for ways to increase their productivity. Are you operating your laser equipment in the most efficient way possible? Here are some tips and tricks to make sure your laser equipment is operating according to its full potential.

1. Record multiple items in a single batch

Printing multiple items will reduce your production time. If you have a project that requires recording more than one item with the same or similar designs, such as plates or coasters, print multiple pieces simultaneously, instead of one by one. We have found that recording in batches will save users up to 37% of the time. The amount you record each time will depend on the size of the table, and to do this, you must expand the page size in your graphic design program to match the maximum table size of your laser system. Then you can fill the table with pieces and record them all at the same time. You may also find it practical to use a pattern to properly space the items.

2. Adjust the resolution

Resolution is another factor that you should consider when you want to increase productivity. A clear image is important in any engraving job, but the more PPP you want, the longer the article will take to be recorded. PPP refers to points per inch and the higher the PPP value, the closer the recorded points will be. This results in a recorded image with a high level of detail, but it may take longer than you would like. By lowering the resolution a bit, you can increase the time savings by up to 33% or more. To compensate for a lower resolution, you can use different blur patterns that you will find in the Epilog print driver. Blurring eliminates visual patterns of points that can be seen in a low PPP and randomizes them, which in turn hides the lower resolution. By finding the right combination of resolution and blur pattern, you can achieve a result that looks good and takes less time to produce.

3. Use the color assignment

You can also use color mapping to save engraving time. Let’s say you have a design with three columns, each with about 20 names. By default, the laser equipment displays it as a single image and the laser head will be moved over the blank space between the columns to record the complete design you have sent to print. The color assignment allows you to skip all that blank space by assigning each column a different color and a specific engraving order. With this method, the laser will record one column at a time, only moving over the blank space between the columns when it is time to advance to the next group of names. This approach can save you time on 43%, depending on the items you are recording.

4. Prerecorded items

Personalization is very popular, and therefore a great business opportunity, but exclusive jobs can be very inefficient. Loading the same design over and over again to record the same item multiple times can consume a good part of your production time. We suggest prerecording an inventory of popular items before orders are entered. Take this cutting board as an example. You can easily pre-engrave the main design on a batch of cutting boards. Once you receive the order, locate one of the cutting boards on the device and add a last name or other personalized phrase at the point of the “order here” section. This additional step will take very little time compared to printing the entire design. By making part of the effort at the beginning, you can avoid bottlenecks in your daily workflow.

5. Use center engraving

Another tip is to use center engraving to quickly organize personalized works on items such as phones, awards or any item that requires focused text or designs. Center engraving makes it easy to work with elements of different sizes without seeing the need to create a custom template for each one. This feature allows the user to move the laser manually to the center of the object being engraved. Set the center point as the new starting position and the laser will use that point to properly locate the design. Compared to custom file settings, this method will save you a lot of time!

We hope that these tips and tricks help you shorten the time needed to implement these cutting. And engraving adventures, and make it more productive. Happy laser work!

Focal distances of CO2 Laser Lenses-Bunny

The lenses use to concentrate the laser beam in CO2 laser machines. There are many lens options and these depend on the laser wavelength, power, focal length, etc … . That is why there is so much variety of optical elements. We will find several types of lenses that can use: concave convex, flat-convex . Normally in our machines, we use the flat-convex.

What is the focal length?

Focal length is one of the parameters that define the lens. When the laser beam concentrate, an inverted double cone effect occurs, where the center point between the 2 cones (junction point) becomes the focal point or spot. The size of the focal point is directly proportional to the focal length of the lens. And inversely proportional to the diameter of the beam at the lens inlet.

The distance between the underside of the lens and the focal point is called the focal length and is measured in inches. The greater the focal length, the greater the depth of field. In this way, a short focal lens is ideal for cutting fine materials or making engraving. Since the point is smaller, there is more energy concentration. And we can achieve a greater definition of marking / engraving.

On the other hand, a lens with a greater focal length (from 2.5 ″) will be perfect for cutting thick materials. The cut will be straight due to a smaller divergence of the laser beam. If we try to cut fine materials, we will find that it has a lower concentration of energy and low resolution in the marking, so it will not be adequate.

For the wavy material, on the other hand, a long focal lens will go very well because, having greater depth of field, in the highest and lowest areas you can cut evenly, however with a short focal lens, the cut will not be uniform.

5 common mistakes in laser engraving and how to avoid them-Bunny

Error 1: The laser burns the fabric when it tries to burn it

The first step to avoid burning the fabric with laser engraving and cutting equipment understand which fabrics can resist the process and at what temperatures. Thicker fabrics, such as denim, canvas and leather, can withstand more powerful settings during engraving. But when it comes to delicate fabrics, it is important to start with the adjustments in high speed (at 100% or near that value) and low power (around 5% to 10%). Perform tests with these initial adjustments on any scrap piece and if the fabric can withstand them, increase the power gradually until you get the results you are looking for.

If you need to record directly on a garment, it is advisable to decrease the amount of dots per inch (PPP) that you use to record. The higher the number of PPP, the greater the amount of material that remove. If you record with a lower PPP setting, the laser only slightly vaporizes the top layer and does not burn the fabric until it transferre. Most fabric prints work well with settings of 150 to 300 PPP.

Error 2: Acrylic does not produce frosty white engraving

This is most likely to happen because the acrylic you are using is not correct for the application. Normally two types of acrylic are used in laser engraving and both are suitable for different applications.

Molded acrylic plates and objects are made with a liquid acrylic that is poured into molds to solidify it in various sizes and shapes. This type of acrylic is ideal for making prints because it produces a white frosting perfect for awards and plates. It can be laser cut, but does not produce flame polished edges.

The other type of acrylic used in laser engraving call extruded acrylic, and form from plates in a machine. Extruded acrylic is usually less expensive than molded acrylic because its manufacturing technique allows it to create in larger volumes. However, it reacts very differently in laser engraving equipment. This type of acrylic cut cleanly and uniformly and produces a flame-polished edge; however, when it recorded, it does not produce a frosty appearance, but rather a transparent engraving. Therefore, if you want to get a frosty white finish, you should make sure to use molded acrylic.

Error 3: Irregular Glass Engraving

Frequently, when the laser touches the glass, it cracks the surface but does not engrave deeply or remove the material needed to completely etch. The cracked glass surface produces a frosty appearance, but it can be rough and splintered, depending on the type of glass you are using. While the frosty appearance somewhat desirable, the same cannot said of a rough or splintered surface.

To obtain a uniform frosty finish, try one or more of the following tips:

  • Use a lower resolution of about 300 PPP, which will produce a better result in the glass as it increases the separation between the points that are recorded.
  • Change the black setting of your image to 80% black.
  • Run the laser engraver with Jarvis Blur (this blur pattern can found in the Epilog print controller), which will help provide a uniform finish.
  • Sometimes, putting a sheet of newspaper or a wet paper towel in the etching area helps dissipate heat and improves the etching process. Just make sure you don’t leave wrinkles on the paper when you put it on.
  • Another way to dissipate heat apply a thin layer of liquid soap to the area that etched. Either with your finger or with a paper towel.
  • Finally, if there are glass chips after engraving, polish the area with a scrubbing sponge that does not scratch.

Error 4: Wood engraving produces different results with the same configuration

Different woods have different reactions when etched with laser and produce different results. Lighter woods, such as cherry or maple, produce a pleasant contrast in the area that the laser burns, while cut or engrave denser woods, more laser power required

Here are some tips for wood engraving:

  • Maple and alder are some of the most popular wood for engraving, because they provide a sharp contrast.
  • Natural wood engraving produces smoke and debris during the process that can embedded in the wood grain. To reduce this effect, always record from the bottom up, as this helps keep smoke away from engraving.
  • When you burn stained wood, you remove excess smoke and debris from the surface with a damp cloth after burning.

Error 5: The laser engraver no longer works as fast as before

Clean your equipment! As with other types of design equipment, a machine produces better results than one that not properly maintained. The maintenance requirements indicated in the user manual of your laser equipment. If performance has declined rapidly, checking and cleaning the optical components may be the first step in correcting the problem.

We recommend inspecting the laser’s optical components (lenses and mirrors) every week and cleaning them when necessary. If you cut materials that produce a greater amount of waste, such as wood or acrylic. It need to clean these components more frequently. Typically, the optical elements are light golden in color and shine. If they are opaque or have stains and dirt, it is time to clean them.

 

WHEN IS THE RIGHT TIME TO CHANGE YOUR LASER CUTTER-Bunny

Production level

The demands of the market increasingly demand. So your production must maintain and increasingly more efficient to be able to give the width that your customers expect. Your machine must know how to respond to the current situation of your production. But it must also be able to give the width when the production of your company increases. There may be greater needs to cover and important and unforeseen opportunities that cannot be missed. Therefore, it is vital to have a team that can respond to a production increase.

Reprocesses

When you are thinking about the effectiveness of your processes, reducing waste is the solution to avoid reprocessing your products. This is why if you currently have to put your raw material into several reprocesses. It is necessary to consider acquiring a laser cutter. Since this will only take time and make you spend important resources that you could invest in other needs. In this way you can occupy only one machine instead of several and thus save time and money.

Maquila

When you send a large part of your production to make up. It is very likely that you are not only wasting your time and money, remember that only you know the quality that your product should have. And when you send make up you leave the quality of your products in the hands of third parties who do not know The value of the product. That is why it is necessary to take control of your production to ensure the quality that you offer to your customers, a goal that you will achieve by acquiring a laser cutter.

Explore new industries.

It is possible that you are looking to expand your company, which means that it is necessary to have a machine that not only can give you the quality for your current processes. But is able to respond if you need to work new materials. This can be achieved with a laser cutter, which is capable of opening the doors to the versatility you require.

Search for better finishes.

It is not new that the quality of your products is always looking for the best. So your finishes have to reflect this. If your machine is not giving you the precision in the finishes it is time to consider a change to a laser cutter since with this machine you will achieve precise. And millimeter processes, leaving behind errors and cutting failures.

Improve response times.

The most significant difference between an automated procedure and a traditional process is the time of production and, consequently, of delivery and response times to your customers. In order to continue offering the service that characterizes you. It is necessary to take into account the importance of having automated processes. This will only achieve by switching to a laser cutter, with which you will achieve an 80% increase in your production.

These are some situations that can occur on a daily basis, which need tangible and efficient solutions so that they do not affect your production. If you feel identified with any of these situations. It is necessary to find a machine that can give the width you are looking for. Do not waste more time and contact our experts. They have the tools and knowledge to give you the best option.

That is why in XT LASER we distinguish ourselves by having the best options for you in terms of machinery, after-sales service and financing.

How to Align a Laser Cutting Machine or Laser Cutter-Bunny

To properly align the mirrors of a laser cutter or a laser engraver you have to understand some concepts. It all comes down to knowing the components involved in the process. And understand how the laser beam is transported from the laser tube to the material we want to work.

We will define a glossary to understand each other throughout the tutorial:

Optical Components / Supplies:

Laser tube: It is the glass tube that is in the machine. Within it the laser medium (the laser beam) is generated. This component is an input that is changed when the gas inside is exhausted.

A – Mirror 1: It is the mirror that is next to the laser tube.

B – Mirror 2: It is the mirror that is at the tip of the bridge.

C – Mirror 3: It is the mirror that is at the top of the head.

D – Lens: It is located in the head, more precisely in the nozzle, near the peak. It is the component that focuses the laser beam at a point that is very small (less than 1/2 mm), it is also where the laser beam burns with greater power.

Component Stands
E – Tube supports: They are the ones that support the tube, they are below it. They can be adjustable or fixed.

F – Mirror stands: They are the ones that hold the mirrors. They are 3 different supports but the function is the same to hold the laser mirrors and also have the mirror regulators.

G – Lens support / Nozzle: It is an aluminum spout located in the head. Inside it is the focus lens, which is held by a nut.

Regulators

H – Mirror regulators: these are screws with counter nut that move the mirrors to adjust the trajectory of the laser beam. They can be two or 3 depending on the model.

I – Mirror support regulators: these are screws that adjust the supports of the mirrors to the structure of the machine. IMPORTANT: These should rarely be touched because a minimum movement of them radically changes (moves a lot) the path of the laser beam. This can incur physical damage to people and lightning can leave the machine.

J – Tube support regulators: they are used to raise or lower the tube in order to level the output of the laser beam.

The Optical Circuit, Laser Beam Transport

The optical circuit is all of the components mentioned above, through these the laser beam is transported until it reaches the material.

For proper alignment it is necessary to understand that from the laser tube to the focusing lens, the laser beam must go straight, bouncing in the center of the mirrors and passing through the center of the lens. This should be the same throughout the work area.

If the tube is uneven horizontally or vertically, the laser beam will be misaligned from the beginning and it will be very difficult to align it with the mirrors.

Between the mirror Nº 1 and the mirror Nº 2 the laser beam is aligned on the entire Y axis of the machine; that is from back to front and vice versa throughout the table.

Between the mirror Nº 2 and the mirror Nº 3 the laser beam is aligned on the entire X axis of the machine; that is from left to right and vice versa throughout the table.

Between the mirror No. 3 and the lens, the perpendicularity of the laser beam is aligned with respect to the lens and the material.

Symptoms that My Machine Needs Alignment

Although they can mean another type of damage. These 3 points are indicators that the alignment of mirrors of our laser machine need to be verified:

The laser cutting machine cuts in some parts of the work area and not in others.
The impact of the laser beam against the material leaves a shadow.
The machine does not cut with the power and speed it should.
Well now that we have more information on how the optical circuit works. And what are the parts we will start the calibration process.

We recommend using a power from medium to low, between 50% and 20% of the laser beam to do the tests. When the power is lowered to the laser beam the “diameter” of the beam is smaller. And its power too, so we will have a smaller and more accurate brand.

To verify where the laser beam impacts on the mirrors, depending on the type of mirror support your machine has. You should use paper tape. Or cut acrylic glass with paper tape attached to the mirror supports.

This is because in some media when putting tape. This is very close to the mirror and when the beam is fired the tape burns and dirties the mirror. In other cases there are supports that have a “perforated profile” that is separated from the mirrors. Thought just to put tape and not dirty the mirror.
