Error 1: The laser heats the cloth as it attempts to melt it.
The first step to prevent burning the cloth with laser engraving and cutting equipment is to learn which fabrics will withstand the process and at what temperatures. The thicker materials, such as cotton, canvas and leather, will tolerate more powerful engraving conditions. But when it comes to fragile fabrics, it is critical to start with high-speed (100 percent or close to that value) and low-power changes (around 5 percent to 10 percent ). Test with these initial modifications on every scrap item, and if the fabric can handle it, raise the power steadily before you get the results you're looking for.
If you need to record directly on a garment, it is advisable to reduce the number of dots per inch (PPP) you use to record. The higher the number of PPPs, the greater the quantity of substance to be removed. If you record with a lower PPP configuration, the laser just marginally vaporizes the top layer and does not flame the cloth until it is transferred. Most of the cloth prints fit well with settings between 150 and 300 PPP.
Error 2: Acrylic does not yield glossy white engraving
This is more likely to be when the acrylic that you are using is not right for the sample. Normally, two grades of acrylic are used in laser engraving and are suitable for various applications.
The molded acrylic plates and pieces are made of liquid acrylic, which is poured into molds to solidify them in different sizes and shapes. This kind of acrylic is suitable for printing because it makes the perfect white frosting for awards and plates. It can be laser cut, but it does not yield polished edges of flame.
The other kind of acrylic used in laser engraving extruded acrylic, and the shape of plates in the machine. Extruded acrylic is normally cheaper than molded acrylic because its processing process enables it to be produced in larger quantities. However, the laser engraving equipment responds very differently. This sort of acrylic cut cleanly and evenly and creates a flame-polished edge; however, when photographed, it does not produce a frosty look, but rather a clear engraving. Therefore, if you wish to get a frosty white look, make sure you use acrylic molded finish.
Error 3: Irregular engraving of glass
Frequently, as the laser strikes the glass, it fractures the surface but does not fully engrave or strip the substance required to absolutely etch. The broken glass surface provides a frosty look, but it can be rough and split, depending on the kind of glass you are using. While the frosty look is somewhat attractive, the same cannot be said of a rough or split base.In order to achieve a uniform frosty finish, attempt one or more of the following tips:
Use a lower resolution of around 300 PPP, which will yield a stronger outcome in the glass as it improves the separation between the registered points. Change the black setting of your picture to 80% black. Run the Jarvis Blur laser engraver (this blur pattern can be found in the Epilog Print Controller) to help ensure a consistent finish. Often, placing a sheet of paper or a wet paper towel in the etching region helps dissipate heat and increases the etching operation. Just make sure that when you put it on, you don't leave wrinkles on the page. A thin layer of liquid soap is applied to the region that has been etched in some way to dissipate heat.
Either with a thumbnail or a paper towel. Finally, if there are glass chips after engraving, polish the region with a scrubbing sponge that doesn't itch.
Error 4: Wood engraving yields inconsistent effects in the same setup. Similar woods have different reactions when they are engraved with a laser and yield different effects. Lighter trees, such as cherry or maple, provide a good contrast in the region where the laser burns, when cutting or engraving denser woods, need more laser power.
Here are few tips for wooden engraving:
Maple and alder are some of the most common wood for carving, since they provide a strong contrast.
Natural wood engraving creates smoke and debris during the process that may be trapped in the grain of wood. To reduce this impact, often record from the bottom up, as this helps to keep the smoke away from the engraving. When you fire stained wood, after burning, you clean excess smoke and ashes from the soil with a damp cloth.
Error 5: The laser engraver is no longer working as quickly as before.
Clean up your tools! As for most construction equipment, the system achieves greater performance than one that is not adequately managed. Maintenance specifications stated in the user manual for your laser devices. If output has decreased rapidly, testing and cleaning the optical components can be the first step in correcting the problem.
It is recommended that the optical components (lenses and mirrors) of the laser be checked every week and, if possible, cleaned. If you cut products that contain a larger volume of waste, such as timber or acrylic. These elements need to be cleaned more regularly. Usually, the optical components are light golden in color and shine. If they're opaque or have streaks and debris, it's time to patch them up.
