3. Set the port
After installing the driver, open the device manager of the computer and click on the port option to see the content
inside the red box on the screen shown in the figure below (the port information is in brackets).
Remember the port information queried above, switch to the Candle software interface and click the "Settings" option
in the upper left corner. Selecting the setting will bring up the interface. Under "Connection", select the port name you
queried, select the baud rate 115200, and then click below The icon "Finish" ends the setting
Candle software
14
4. Connection is complete
After setting the port and baud rate, click Finish. The status bar at the top right of the Candle interface will show Idle,
and at the same time, the console at the bottom right will display the information shown below, indicating that the
connection has been successfully established.
15
5. Processing documents
The "File" option at the top, click "New" to create a G code in the command bar at the bottom of the interface, and
click "Open" to select a G code file that has been made, and then you can import the file. After importing, the middle
of the interface will display a visual graph composed of tool paths (the position of the pen-shaped graph in the graph
is the current tool position). In the visualization window, hold down the left mouse button to move to rotate the graph,
and hold down the right button to move. Graphics, scrolling the middle wheel can zoom in and out of the graphics.
At the same time, the content of the G code will be displayed in the lower command bar. During processing, the
machine will run one by one according to the G code commands.
16
6. Set the working coordinate origin
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 axis is reset to zero, and the Z axis is reset to zero 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.
17
7.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. (After pausing, click again to continue the
previous engraving. After termination, click Send to start processing from the beginning).
8.Finished processing
After the processing is completed, the visualization window prompts that the engraving is completed and the time
required for engraving.

Engraving material list
Problem summary
The data listed in this list are all reference values. Because each material has different characteristics and differences,
there is a certain error. In general, the use of relatively high power (1600MW is relatively high power compared to
500MW), 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.
Q : What materials can the laser engraving machine engrave or cut?
Please refer to the "Carving Material List"
Q : What is the difference in power size?
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.
However, the pattern carved out by high power is not small enough for fine power. If it is 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: How long does the laser head last?
In theory it is 8,000 hours. (The life of the laser varies depending on the environment and usage of each user. This
issue is for reference only)
Q: How high can the engraving precision be achieved?
The power is different and the precision of the engraving is different. In general, the larger the power, the larger the
laser spot (the spot on the material), so it cannot be engraved fine. In general, low power (300MW 500MW) engrav-
ing accuracy can be achieved.
Q : Which formats or formats are supported?
Support all formats of images, support GCODE, NC files
Q: Is the laser head focal length adjustable?
Adjustable. Click the “Weak Light On” button on the touch screen interface, then rotate the knob under the laser head
to make the spot on the material as small as possible. The smaller the spot, the greater the energy.
Q : Whether to 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 : Is there a positioning function? How to locate?
When using online engraving, you can turn on the low light, move the laser head to the place to be engraved, click
the “Position” button to set the point to zero.
When using offline engraving, turn on the low light, move the laser head to the place to be engraved, click the “Posi-
tion” button to set the point to zero, select the file to be engraved, and confirm the range of the photo to be engraved
by walking the border. For accurate positioning.
22
Q: What is the reason why 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?
Please confirm whether the USB interface is in contact 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). If you still
can't solve it, please contact our customer service or technical staff.
Q: What should I do to engrave something taller?
Since the model is a desktop model, the laser head and the object to be carved must reach a certain distance to
engrave. If it is necessary to engrave a higher object, it is necessary to raise the height of the whole machine and the
object to be carved. For example, take the appropriate plane to raise the 4 feet of the machine, but the adjusted
engraving effect cannot be guaranteed. (After adjustment, remember to refocus)
Q : Can the laser head be replaced by itself?
The laser head is self-replaceable. The L-type M3 Allen key can be used to unscrew the locking laser head, remove
the laser head, replace the laser head, and retighten the screws.
Q: Can you emboss wood?
No. Laser engraving can only be planar engraving. Relief needs high and low float
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 or on the progress bar on the touch screen.
Q : Do I need to brush the motherboard and touch screen?
The motherboard and touch screen factory are already update firmware, no need to re-flash the firmware. If you need
to change the firmware, you can use the Grbl →Grbl configuration →Value on the software,double-click the option
you want to modify to modify it, and then click "Write" to write it.
Q : Where is the motor drive plugged in?
The small drive is 4988 green board (rated current is 1A, the maximum current is 2A), the X-axis motor drive is
inserted in the X-axis motor in-line drive interface below the X-axis motor line interface; the Y-axis motor drive is
connected to the Y-axis The Y-axis motor is directly inserted into the drive interface below the motor line interface,
and the Y1 and Y2 axes share a Y-axis drive. (Note: the direction of the drive is not reversed, and the insertion will
be burned)
There are two ways to distinguish the direction of the drive: 1. Look at the color of the drive and drive interface termi-
nals.(black and green), the corresponding color can be inserted. 2. Check the words on the back of the motherboard
driver interface (such as EN DIR GND, etc.), and insert the words on the corresponding drive (such as EN DIR GND,
etc.).
