Click “Engrave” on the third line on the right side of the interface (the figure on the left) and switch to the following interface (the following figure on the right):
Neje Dk-8-kz Mac Software Downloads
There is a “Pic Type” option in the “Engrave” mode, under which there are two another options: “gray” and “White Black”. What do they mean?
The “White Black” mode refers to display images in black and white. For example, when engraving name, the entered text will be displayed in black. The “gray” mode refers to display images in color or gray. In this mode, the engraved images will show changes in color. The application scenarios of these two modes can be compared through the following figures. It is strongly recommended to engrave black-and-white (colorless) images in the black and white mode; otherwise some image details will be lost.
Select “White Black” mode and then click “Start” to start engraving. The result is as shown below:
Select “gray mode” and click “Start” to start engraving. The result is as shown below:

2) Select a photo from your computer
3) click “Open” to access an interface as shown below:
Neje Dk 8 Kz 1000mw
3) Click “Engrave” on the third line on the right side of the interface. There is an “Pic Type” option in this mode, under which there are two another options: “gray” and “White Black”. As the photo to be engraved is a full-color photo, the “gray“ mode should be selected.
4) Click “Preview Engraving Area” to allow the laser to move along a rectangular trajectory which indicates the area for engraving photos.
5) Click “Start” to allow LaserBot to engrave the photo.
Simple principle of image processing:
It can be seen in the figure above that the gray mode is recommended to engrave images with rich details and the “White Black” mode is recommended to engrave the black-and-white images. In addition, the user should know that images in SVG and DXF are vector graphics and can’t be engraved in the gray mode.
6. Becoming a DIY Geek, Master Your Own LaserBot
To better use LaserBot, you should have some knowledge of the parameters in mLaser. The parameters to be set in the process of using mLaser are introduced in this chapter to allow you to use it more flexibly. There are two working modes in mLaser : “Cut” and “Engrave”. As we have learnt the difference between these two modes, their parameters are introduced in details in this chapter.
1) Cut
The engraving work is completed at a power level. The parameters are as follows:
– Material: the program will automatically set appropriate parameters for different materials, without the need to set other parameters by the user.
– Repetition Times: thick materials may need to be repeatedly cut.
– Laser Power: light power during laser cutting in percentage with the maximum value being 100%.
– Speed over Pixels: the movement speed in the engraving process when the laser is turned on, with a movement of 300 mm per minute by default.
– Travel Speed: the movement speed in the engraving process when the laser is turned off, with a movement of 2,000 mm per minute by default.
2) Engrave
Parameters can be modified according to different situations in “Engrave” mode. Default parameters are shown as follows in mLaser:
– Pic Type: images can be processed in the “gray” mode and the“White Black”mode. The way to select these two modes has been introduced above.
– Print Speed: movement speed refers to the speed to engrave the blanks in the “Engrave” mode. As the laser will move in the form as a laser spot, the depth of a pixel point will be controlled through controlling the light intensity and irradiation time of the laser to achieve the effect of grayscale engraving.
– Laser Power: the power when the laser is turned on, with a maximum value of 100%.
– Engraving Time: the time for burning a pixel point in mm. The shorter the time is, the less obvious the effect will be.
– Pixel Interval: whether the engraving work should be carried out at intervals. When the value is 1, each pixel will be engraved, thus producing the best effect. When the value is 2, the engraving work will be carried out every other pixel. When the value is 3, the engraving work will be carried out every two pixels, and so on.
FAQ
Q1: Why does my PC fail to install the makeblock MegaPi Driver?
A：For MegaPi, the main control chip is Mega2560 and driver chip is CH340. For some computers, the driver may not be automatically installed, so you have to install the Driver manually.
The complete installation process of Arduino and driver is as below. (Note: You may skip the steps for installing Arduino, and only install CH340 driver)
Arduino is an open-source platform based on easy-to-use hardware and software. It includes a development environment (IDE) and library. The IDE is written in Java and based on processing environment. We provide a complete Arduino development environment for users.
Step 1: Download Arduino IDE and install Arduino driver
- Arduino IDE installation package: Windows / Mac OSX / Linux ( 32Bit | 64Bit )
- Arduino driver:
Windows : Download
Mac OSX : Me Baseboard / Makeblock Orion（CH340 driver, compatible with MegaPi mainboard） / Arduino Uno
Neje Dk 8 Kz Setup
Step2: Install Makeblock Library for Arduino
(Note: The Arduino installation package for windows has integrated the Makeblock library.)
1.Download the library zip package at: https://github.com/Makeblock-official/Makeblock-Libraries/archive/master.zip
2. Decompress the makeblock folder in the zip to the Arduino default library:
- Windows 7: “[arduino installation directory]libraries”Your Arduino library folder now looks like this (on Windows):
[arduino installation directory]librariesmakeblocksrc
[arduino installation directory]librariesmakeblockexample
…. - or like this (on Mac):
[arduino directory]ContentsJavalibrariesmakeblocksrc
[arduino directory]ContentsJavalibrariesmakeblockexample
… - or similarly for Linux.
3. Open Arduino IDE. If it is opened, you need to restart to see changes.
4. Click “File->Examples” to check sample code under Makeblock folder.
Q2: Why is the suite complete with video building course?
A: That is because it is Geek suite so that video display is more vivid and detailed. 3D model may be used to check assembly details, please click this hyperlink to check or download 3D model.
Q3: How can I adjust the precision if it is not sufficient in the laser-engraving image?
A: A file of standard square may be imported for test. The test method is as below.
1. Click this hyperlink to download test file
2. Start mLaser software, enter it and switch to the advanced mode. Click three-bar icon→interface selection→advanced mode at the top right of the software.
3. Open→Square Test.svg→adjust the size to be 40×40 mm.
5.1 Adjust installation of X and Y axis to make them vertical, as seen in notes at 4:40 in the building video.
5.2 Initial tensioning may be done when Y-axis timing belt is tensioned. Choose U bracket as a referrence at the time of final tensioning to make the two timing belts locked tightly and moving synchronously. Y-axis is perpendicular to X-axis. This part may need repeated adjustments to ensue precision.
5.3 The timing belt of X-axis and Y-axis shall be properly tight so that the tensioned timing belt is slightly elastic. The M3 set screws of 6 timing belt wheels are required to be locked tightly, or slip may occur, thus causing loss in machine precision. As 512 mm × 4 mm shaft on Y-axis is used for guaranteeing synchronous driving, the 2 18T timing belt wheel on it require adjustment and tight locking. (Locking shall guarantee verticality and uniformity of Y-axix and X-axis)
5.4 X-axis and Y-axis roller shall be installed to guarantee smoothness and proper tightness. Smoothness means smooth slip without any blockage, while proper tightness means tightly locked screws and that slider does not shake. All these require careful adjustment. Please make adjustment patiently.
5.5 After the above adjustments, get the laser head to manually slide within the operation range to check smoothness. If it is less smooth, adjust it again.
5.6 Repeat steps 1, 2 3, 4 under this question, until a normal square is drawn.
Q4: Normal upgrading of firmware is not possible for mLaser.
Best Free Mac Software Download
A: If firmware cannot be abnormally burnt during use, re-plug USB. If there is not any serial port, please install CH340 driver in the way as mentioned in Q1, and then burn the firmware. If the firmware remains not to be burnt, it is suggested to restart the computer or contact the customer service through tec-supprt@makeblock.com or by joining into the QQ Group, 324113572.
Q5: Why does mLaser not well support DXF format?
A: That is because DXF is complicated. The existing mLaser software makes abnormal opening of DXF format generated directly. It is suggested to use *.svg or transform into the common format *.svg.
Q6: Why does mLaser opening file have a large bounding frame and how can this problem be solved?
A: Current mLaser edition displays SVG file in a similar way that browser opens SVG files, so displaying effect is not different. Specific method for obtaining SVG file with a displaying effect of final wireframe format is as below.
1. Download and install inkscape software.
2. Reserve displaying way of wireframe only
2.1 Select files, click the button X at the lower left corner of Inkscape interface for removing the filling content.
2.2 Check→display→wireframe for changing display into wireframe mode.
2.3 Recommended saving format: file→save-as→save-as format→common SVG format (*.svg)→save
Q7: How can files of vector format such as AI.Coreldraw and CAD be converted into SVG files?
A: The Internet may be used for search of relevant introductions. The general method is to save vector format as general format, such as dxf. Then use Coreldraw software to open and save as Coreldraw format. Then open it with inkscape and convert the format in the way as mentioned in Q6.
Q8: What is G-code format of mLaser?
