10 useful tips for working with a laser engraver on wood and plywood .

Hello everyone, Friends! 3DTool is with you!

CO2 laser cutting machine. 10 helpful tips for beginners on cutting and engraving plywood and wood.

Foreword. For some of the tips, it's important to understand the difference between vector files and raster files. Vector files are mathematical formulas that describe lines, circles, and so on. They are created in programs such as Adobe Illustrator, Inkscape, AutoCAD, and Corel. Raster files are collections of individual pixels, such as digital photos, Adobe Photoshop files, JPG files, etc. You can only laser cut vector files, but engrave both types. Some of the tips listed below require your file to be a vector file. nine0003

Tip #1. Preparation for laser cutting or engraving.

Before we move on to cutting and engraving tips, let's start with some helpful tips for preparing for them:

Smoke/Slag Resistant: If you are going to engrave anything, be aware that smoke/smudge from engraving can stain the edges of the engraved surface. To avoid this, stick masking tape on the surface. It won't affect the power of the laser much (you can increase the power a little if you think it's necessary), but it will protect the material around the area being engraved from smoke trails. Once engraved, simply peel off the tape. nine0003

Presets: The laser machine you are using probably has the recommended settings for cutting or engraving different materials and different thicknesses. You can download these settings to your computer or the laser cutting machine control board directly and save them as presets. Be sure to name them something meaningful so that they can be easily identified in the future. So the next time you engrave leather or cut 3mm acrylic, you can simply find and use a preset to work with that material. nine0003

Test cutting of a workpiece: Even if you have a preset for material cutting, it is recommended to perform a test cut before starting the main job. There is nothing worse than taking out a sheet of plywood material after a laser cut and discovering that it did not cut all the way to the end. We recommend creating a small circle or square (about 6 or 10 mm wide) and cutting it into the corner of the piece. In this way, you can see if you need to increase or decrease the power before starting the base job. nine0003

Tip #2: The Importance of Layers in Image Editors

Some of the tips below require the ability to engrave/cut only part of a file or design at a time. The easiest way to do this is to put different parts of your design on different layers of the same file. Most graphics programs allow you to create layers and then turn them on and off. While you can of course put everything on one layer, having multiple layers gives you several key benefits: nine0003

1 . Cut order control. Your laser machine will most likely have several options for controlling the order in which cuts occur, but the most convenient way to control the order is in one single way: set different cut lines on separate layers to turn each layer on and off in the desired order.

2 . Multiple layers in one file. Instead of saving each design or part of the design in a separate file, just put them all in one file and break them into separate layers. Then just run the desired layers. nine0003

3 . Create hints and targets. Perhaps you've created a few clues to lay out your design, or a target for placing multiple identical objects. To prevent them from being cut out on the main design, put them on a separate layer and just turn it off.

Tip #3: Laser cutting and wood engraving techniques.

Let's say you've designed a logo or image and want to carve it into solid wood. Wood is a great material for engraving, but you need to understand the difference between engraving on a solid piece of wood and a composite material like plywood or MDF. Unlike manufactured material, natural wood is not homogeneous. The fibers in wood represent different stages of growth (winter and summer) and each will burn differently. Usually the dark fibers are harder and the light parts in between are softer. As you can see from the sample photo above, you see a zebra in the engraving. If a uniform engraving is important to you, your best bet is good plywood, where the top layer is more predictable. nine0003

Another thing to keep in mind is materials with a thin veneer of good wood on top. Engraving often burns through thin veneer, exposing what lies underneath. Make sure the wood underneath the veneer looks good and that you burn all the veneer out so you don't have a mixture of veneer and surface underneath.

Tip #4: Laser cutting overlapping objects.

Often, when you need to cut several parts at the same time, it is tempting to place them next to each other so that adjacent identical lines overlap each other to save a sheet of material. It's a good idea, but it can be messed up very easily. nine0003

For example, you have a bunch of squares for cutting. If you draw two squares (four sides each) and then press them together, there will only be visually one line between them. The problem is that although it looks like one solid line to you, the computer still sees two. The end result is that the lines will be cut off one by one. This will cause that edge to be more likely to be scorched rather than clean. It will also waste time on an unnecessary cut. nine0003

The way to fix this is to remove one of the doubled lines. Draw one of the squares 3 sided, deleting one side line opposite the first square and align them.

Tip #5: The difference between bitmap and vector laser engraving.

The main difference between raster engraving and vector engraving is that for engraving, the laser moves from left to right across the engraving area and then moves down a minimum step, repeating until the image is engraved. With a vector cut, the laser simply moves along the lines. As a result, raster engraving takes much longer than vector engraving. nine0003

So, you have a drawing. For example, the Celtic knot, which is basically just lines. Of course, you can run it as a bitmap engraving. The advantage is that you can set the thickness of the lines to whatever you want, and different lines will have different thicknesses. The downside is that engraving will take much longer.

If the file is vector, there is a quick way to create lines without cutting them. Run your file as a vector cut, but turn off the power and increase the speed. For example, to cut through 3mm plywood, we set the laser power to 100% and the speed to 20%, but to draw a line on it, we reduce the power to 30% and the speed to 9five%. Trying to cut through the material, the laser simply burns a thin line on it. The advantage is that this will be much faster than vector engraving. The downside is that the line will be very thin and you won't be able to change its thickness.

Tip #6: Defocus the laser beam for thicker vector lines.

In the last tip, we looked at how to use a vector image to simply draw lines on material to create line art or designs. But the disadvantage of this method is that the line is very thin. But there is a way to get thicker lines. The laser beam has a very narrow focus point, so if you lower the material a little, the laser will lose focus and scatter. Lay a small piece of wood about 9 inches thick.5mm on the material you are using and focus the laser on that piece. Then run the laser at the vector setting (lower power and higher speed). The result is a much thicker line than if the laser were correctly focused.

There are 2 drawbacks to this method that you need to be aware of when using this working technique. One of them is that the line is a little inaccurate and not as sharp as with a raster engraving. Secondly, at the corners of the lines, the laser pauses a little as it changes direction, so the corners burn a little deeper. The corners look like they have little dots in them. nine0003

Tip #7: Adding a vector stroke to the edge of a font or engraving image

You should usually get good edges on any engraving your laser does (unless you are checking focus). But if you want to sharpen the edges of the engraving a little more, here's a good tip: add a light vector stroke around the edge of the engraved image.

You will need the image as a vector file. Select it and add a thin stroke (stroke) around the edges. When you set up the laser for stroking, turn down the laser power and increase the speed so that it burns but does not cut through the edges. After the laser has done its basic engraving, it will come back and burn a thin line around the very edge. nine0003

This effect is great for all kinds of inscriptions.

Tip #8: Laser cut wood in the target area.

Sometimes you need to accurately hit a target area that is not at the laser's start coordinates. For example, there is a piece of plastic from which you have already cut out several shapes, but there is enough space between the old cutouts to make another, new cutout. How can you neatly insert a new cut into the remaining space? nine0003

First measure the target area and get its approximate dimensions. Make sure there is enough space for what you want to cut out. Then place the workpiece on the honeycomb table of the laser machine and measure the distance from the zero coordinates of the laser to the target area. For example, a rectangle 2.5cm by 5cm, located 6cm below and 2cm to the left of the edge. Then, in your file, use markup to highlight the target area and position from the origin of the material. Place your drawing or cut in the target area. Make sure that this marking will not be used when cutting. If you measured everything correctly, your notch should be right in the target area. nine0003

Tip #9: Laser Engrave Many Objects Simultaneously and Use Templates.

Let's say you have a lot of wooden coasters that you want to engrave your logo on. You can place them one by one at the laser start coordinates and engrave one by one. But wouldn't it be better to arrange several pieces at the same time and have the laser cutter engrave the image on all the blanks at the same time? nine0003

The trick is to create a grid on which you can lay out the blanks and precisely laser engrave them. Create a new vector file the size of your laser target area. Then measure your image to be replicated on blanks. If you can get it's exact shape this is a great option, but if that's not possible then a regular circle or square will do, as long as the edges of the image fit exactly into the area of ​​the square or circle. This will be your target form. Create a template and place your design (engraving or cutout) in this area. Now copy the template and your drawing and paste as many copies as you can fit within the laser's workspace. nine0003

Tip: Leave some space between the templates so that the blanks do not lie tightly together.

Before you run the file, don't forget to move the grid and template to one layer and your image to another layer. Then turn off printing for the layer with your design on it.

Cut a piece of cardboard/plywood to fit the laser area and place it in the laser. Now make sure only the template layer is set for cutting. Engrave the template on cardstock. You will get a grid that matches the one in the file. Now place the items you are going to engrave on the template marked on the cardboard. Remember to refocus the laser on the top of what you are about to engrave. Now you can disable printing of the target layer and enable printing of the layer directly with the design. nine0003

As long as you don't move the cardboard/plywood, you can just keep laying out new pieces on it, click on the engraving, and repeat until you've done all your work.

Tip #10: Use a laser dot to simulate a job without cutting.

Some laser machines have the ability to turn on the laser pointer, which projects a red dot indicating where the laser beam will work. This is useful for determining where the laser will cut before working on the material itself. Just turn off the laser power and turn on the red dot. Then run the file and see how the red dot moves, as if we were running a task in idle mode. nine0003

One thing to keep in mind is that this method works well with vector lines where the laser/red dot follows the lines, but not so well with engravings where the laser goes back and forth across the engraving area. If you need to use a red dot to figure out where the engraving ends, you can draw a square or circle around the image you want to engrave, and then simply use the red dot to trace around that square in vector mode.
