• Fixture, tool installation and Set the working coordinate origin
  The fixture in the product kit is not assembled. There are four sets in total. The appearance and usage of the assembled fixture are shown in the right figures.

Before running the G code program, you need to find the position of the engraving figure relative to the overall engraving plate. There is a three- axis coordinate system in the visual graphics. The origin of the three-axis coordinate system is the tool setting point of the actual processing graphic.
You can move the tool to determine the position of the engraving graphic relative to the overall engraving plate based on the position of this origin. The engraving figure in the figure below is taken as an example.

After the selected tool position is started, the X/Y and Z axes are reset to zero (the are zeroing and Z axes buttons). Before returning to zero, make sure that the tool approaches the distance of one sheet of paper for engraving, and then return the X/Y and Z axes to zero (please use a flat-bottom sharp knife when engraving, and use a cylindrical milling cutter when machining planes, slots, and holes) The effect is that the sculpted figure will be carved with the blade tip as the origin.
The ER11 collet on the spindle motor should be clamped into the fixed head first, and it must be clamped in place. When installing the cutter, please do not extend the collet too much, as shown in the first figure below.

• Start carving
  After finding the engraving position, click the send button below and the device will automatically start engraving. The status bar at the top right shows running. The visualization window shows that the tool is moving along the tool path. You can choose the pause and stop buttons below when engraving.

About Engraving effect

In general, the use of relatively high power, the engraving depth is relatively deep, but due to the focal length, it will be less detailed than the low power. Small power engraving is shallow but very fine. When engraving, you can adjust the power, engraving speed, and moving speed for better results. In addition, when the speed is slow, it can be cut, but if the edge is not fine and the degree of burning is obvious, you can try to adjust the speed and repeat the engraving several times to achieve better results. If it is cutting, please adjust the speed as appropriate to achieve the cutting effect. If it is engraving, please adjust the parameters such as power and speed according to the depth of engraving.

FAQ

Q: What’s the difference between different power levels?
The higher the power, the greater the luminous energy of the laser head, the higher the temperature of the material hit, the harder the material of the material that can be engraved, and even the full cutting can achieve the cutting effect. If cutting, it is recommended to choose high power; if it is required to engrave shallower, more delicate, it is recommended to choose low power.

Q: Which formats are supported?
Support all formats of images, support GCODE, NC files and so on. If you want to engrave .DXF file, we recommend the LightBurn software.

Q: Does it support the grayscale engraving function?
Supports the grayscale engraving function, which can engrave pictures and photos of different shades of color by controlling the intensity of the laser according to the color depth of the image.

Q: What is the reason that the engraved picture is very light?
Quality: ** line / mm, generally set to 10 lines / mm, the larger the value, the darker the color, the set according to your needs Engraving speed: the moving speed when the laser is turned on, the faster the speed is engraved the shallower. Minimum maximum power: The general minimum power is set to 0 and the maximum power is set to 1000. The greater the maximum power, the deeper the engraved color.

Q: Why does the fan of the laser module not turn?
Please confirm that the laser head is working properly. If the laser head does not work, there may be a bad contact of the power supply line of the laser head; if the laser head works normally, the fan may be broken.

Q: What is the reason for the software connection failed?
Please confirm whether the USB interface is in connect with normal. Please confirm whether the COM port is selected correctly (do not select COM1); please confirm whether the baud rate is selected correctly (select 115200).

Q: How long does it take to engrave a picture?
The length of time required for engraving depends mainly on the speed of the engraving, the speed of the idling, and the size of the picture. Users can view the total time spent on the software.
