The maximum engraving area from edge to edge is 36.76mm, of which: 36.76mm / 500pix = 0.0735mm / pix. The font size of 14pt is at the limit of legibility and its real size is 1 mm. The font size of 24pt real size 1.8mm is still readable. The font size is in, but the engraved size is different from the inkjet printer.Įngraved picture of different font sizes. I have prepared Arial font in various sizes to find out what the smallest font is still legible. This value can be increased in settings, but the total engraving time is then considerably increased due to the wait for each single point. This is probably due to an incorrect synchronization of the retention time before shifting to the next point. The vertical line has weak points on the left side as 'spirits'. The vertical line is interrupted because only one sub-frame was drawn, and then the laser continued to the end of the line. The horizontal line appears to be coarser because it was rendered continuously when the individual points are burnt in line x. The picture shows the intersection of two lines that have both the same thickness of 1 pixel. I plotted the image in paper and then watched under the microscope the size and quality of the engraved pattern. I created a calibration image to fill the entire engraving surface.

The diode can be unscrewed and shifted higher to give you a few more inches of height.Įven the smallest QR code is sufficiently legible. As for the height of the engraved article, the laser beam can be focused by turning the lens on the diode, but the engraved item should not exceed 2cm. This is the first limitation, and that the engraved article can not be too large or heavy to enter the machine and to move the table at all.

It takes a few minutes for the entire area to be rendered.Īttaching the engraved item to a table is resolved using rubber bands. The resulting image then consists of many small black dots. This is how the entire surface is sculpted. When it comes to the end of the row x, the tables move in one yo-yo direction and the next line is plotted. Where there is a black pixel in the image, the laser stops for a while and burns a black dot to the surface of the material. The laser then rake the area by the x-axis rows. The engraving process itself starts with the 'Start' button.

By clicking on 'Preview', the laser renders the square of the square to which the image will be engraved. Click 'Send to machine' to transfer the image to the engraving machine. The program automatically converts the image to black and white to a size of 500 x 500 pixels. Only raster formats are supported: JPG, BMP, and PNG. The image you want to engrave will be dragged into the program window. The program itself is then run as an EXE file. Sometimes antivirus reports a threat, but everything is fine. The current version can be downloaded online. The engraving software is included on the micro-USB card. The maximum engraving area is 37 x 37 mm. At the top there is a red button that can start or stop the engraving process. The second cable with the mini-USB terminal is connected to the computer. The entire device is powered on 5V with an extension USB cable. The horizontal rails are attached to a small table that moves in the y-axis direction. The diode is vertically mounted on the rails, and the servo motor moves in the x-axis direction. The source of laser radiation is an LED with a power of 1W and a wavelength of 405nm. The entire device has an external dimension of 16 x 14 x 19 cm. Built-in 6000mAh polymer li-ion battery, Provide 4A output.

Recently, several generations of mini laser engravers appeared on the market. But I was deterred by hardware reprogramming. Already I wanted to build a laser engraving machine from old napkins. By computer control of this laser beam it is possible to engrave images or cut material. Laser is a source of monochrome light that, thanks to stimulated emission, concentrates high energy into a narrow beam.
