Check whether the Axes and Limit Switches are Properly Installed

Determine whether the serial port is properly connected and whether the MegaPi is properly powered on (the fan does not work if the board is not properly powered on)

1) Click “Control Panel” on the right side of the interface:


2) Adjust the starting position of LaserBot

Click “Home”,LaserBot will perform the reset action and all axes will move to the initial positions of limit switches. In the case that axes do not move towards the direction of limit switches, the power should be turned off immediately. Furthermore, in the case that X axis or Y axis keeps moving after reaching the limit switch, the power should be turned off as well. In the case of a failure in reset, please check whether the wiring is correct again.


If you don’t want LaserBot carve in the default starting point but in the location you specify, you can click Y+ (shortcut key: “W”), Y- (shortcut key: “S”), X- (shortcut key: “A”), X+ (shortcut key: “D”) to adjust the location of LaserBot.

Start your First Laser Engraving

Please ensure that MegaPi is powered on and connected with the computer’s USB before engraving.

Engrave your name

After properly connecting to the serial port, turning on the power, properly resetting and placing the engraving wooden board, you can start your creation. The first task is to engrave your name by LaserBot. You can follow the procedures below:

1) Click “Text”



2) Select the font and font size


3) Enter text


4) Click “Preview Engraving Area” , the laser will move to show a rectangular frame which indicates the area that will be engraved text by LaserBot. If the material is beyond this area, the material should be moved or the initial point for engraving should be adjusted.


5) Click “Start” to engrave your name by LaserBot!


You have successfully engraved your name, but the name only appears outlined, as shown in the following figure:



5.Further steps

To engrave solid words, you need to select another working mode of mLaser, that is, the “Engrave” mode.
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):


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:



Engrave your photos:

You have learnt the way to engrave your name. Then how to engrave photos?

1) Click the “Open” button on the top left corner to access the interface as shown below:


2) Select a photo from your computer


3) click “Open” to access an interface as shown below:


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.



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

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:

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]\libraries\makeblock\src
    [arduino installation directory]\libraries\makeblock\example
  • or like this (on Mac):
    [arduino directory]\Contents\Java\libraries\makeblock\src
    [arduino directory]\Contents\Javalibraries\makeblock\example
  • 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.

4. Set the laser parameters and the engraving starting point. Use frame preview function to adjust position. Then click “start” to start engraving. The comparison of normal and abnormal cases is as below. The abnormal case has such problems as deformation, parralellagram and incorrect length-width ratio.
5. Generation of abnormal engraving images is mainly due to failure of LaserBot to strictly comply with video course in the building process, thus causing X axis and Y axis to be not vertical, and timing belt drive to be loosening and not be synchronous. The troubleshooting is as below:

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.

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 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?

A:The standard G-code instructions used in LaserBot

The standard G-code instructions used in LaserBot, show on table below:

Instruction Name Instruction Parameter Illustrate
G0 X100  Y100 F200 Movement when laser head turns off, movement coordinates of XY back street (depending on whether it is absolute or relative movement), F followed by the speed, in mm / min
G1 Same with G0 Same with G0
G28 X Y F X Y represents the reset axis, F represents the reset speed
G90 \ Set to absolute positioning
G91 \ Set to relative positioning
G92 X  Y Set the current position to the specified position
M92 X Y Set the angle of rotation per mm
M114 \ Get the current position

Customized Gcode instructions set in LaserBot

Instruction Name Instruction Parameter Illustrate
M4 P P followed by a range of numbers from 0 to 256, represents the pwm given by laser head
M800 P P followed by the rotation angle of the servo

Q9: If LaserBot built in accordance with LaserBot Builing Video is found not to be consistent with the right running direction of the software, how can I solve this problem?

A: It is a rare situation. It is generally a result of incorrect factory default direction of stepping motor. Please find out the stepping motor which runs in opposite direction and whose default wiring order is black, green, red and blue. Then you may change the wiring order to change the running direction of stepping motor to be green, black, red and blue, for instance.

  1. The software is great!Compared to my XY Plotter,Laserbot is really easier to use but is also very precise.

  2. After assembly the test “M” is distorted along the Y axis, coming out at 200mm tall but 50mm wide. This ought to be around 120mm square I believe so could you advise next steps on diagnosis and correction?

      1. I just assembled mine and have the same issue. The test M is much taller than it should be so the Y axis is off.
        What next?

        1. Dear Kyle,
          We are so sorry for the trouble caused, and our tech support crew has been followed up your case via e-mail.
          Best regards,

  3. I purchased the kit from Amazon in the US and the quality of the fasteners is quite poor. I managed to strip some of the threads while screwing it in by hand. I am going to buy some quality fasteners from Home Depot and hopefully that fixes the problem.
    Some of the M4 fasteners are also missing. The size of the Guide Rail Guide seems to be smaller than the guide rail. That means that the gantry is not going to slide smoothly. I am now making new ones so they can slide easily. Luckily I have access to the equipment and materials but find that overall quality quite poor so far. I don’t even have it assembled yet. Hopefully the laser head works.

    1. Hi Zef,

      Normally, the size for the mechanical parts should match each other. When you assemble the Guide Rail to the Slid beam, make sure the roller is assembled properly on the Guide Rail slide and put it to the slot on the slide beam properly either.
      Since you mentioned the gantry is not going to slide smoothly, are you able to pull it by hand?
      For further issue, kindly send email to, it is appreciated if you can feedback with some pictures.

  4. Good day.

    Please, I made the first check for the LaserBot, by printing a text, and the results is reflected along the X axis. The text appears from right to left.

    Please, could you provide an orientation to solve this?

    Thank you very much.


    1. Hi Raul,

      Sorry that we may not understand the problem properly.
      Did you test the M,Could you please kindly take a picture for the test result?
      For further feedback, please kindly send email to, thanks!

  5. Hi makeblock team,
    I got my laserbot and already tested it. It works exact except of the x-axis. The scale of the x-axis is four times as large as it should be. For example: The M of the testcut in MLaser is 5 cm wide and 20 cm tall. I did a test printing a text with 10.5 points arial in engraving mode and it is also to tall. There is only one line each four motor steps.
    Can you help me?

    1. Hi MaMuelli,

      Could you please send the picture for the testing result?
      Besides, please exchange the places of the two MegaPi stepper motor drivers, then check if the y-axis is four times as large as it should be?
      For further feedback, please send an email to

      1. Hi Daisy,
        I did sent test pictures to your pm. After changing the two MegaPi stepper motor drivers the testprint has the right height but the wrong width. Are those stepper motor drivers broken or do they have the wrong firmware or what else?
        What can I do to get the right dimensions out of the LaserBot?

        1. Hi MaMuelli,

          Thanks for your email and we have replied you further by email, please kindly check!

  6. So far awesome. However occasionally in cut mode it will “forget” to run a line. Also, language is set to English but the submenu when I right click is still in Chinese

    1. Hi, Rory,
      If the cut mode skip to run a line, please refer to the FAQ 5.”Generation of abnormal engraving images is mainly due to failure of LaserBot to strictly comply with video course in the building process.”
      In terms of the language issue, could you please take a screenshot and send it to ?

  7. How do I get version 2.4 of mlaser in english?
    The v2.3 rar file installed in english, but all v2.4 files end up installing in chinese.
    Please help.

        1. Yes, you could customize the engraving area by using mLaser, which is the software to run Laserbot, to set engraving starting point.

          1. Hi, Ashley,
            Have you dragged the bottom right blue corner or double click the image to adjust the working area?

    1. Hi Marty,

      There is a Processable Material list on this page, please check what is the material of your round objects, then compare it with the materials in the list.

    1. Hi, Nicole,
      Yes, the LaserBot could work with leather, and you could find the leather picture with engrave works on this link.

  8. I need to make several engravings and can only make one per log-in to mlaser. It is frustrating to open the program (log in connect serial lode image set size and all and then after engraving have to closer the program and go through opening the program again, This happens every engraving and when I am making 5 to 8 of the same image it is taking a lot of time just setting the program. Is this supposed to be happening and if so Why?

    1. Dear Gene,
      Have you clicked “Stop” after each engraving? We have tested using mLaser to engrave the same image a couple times, but we don’t need to close and open the software per engraving. After finished the engraving, we clicked “Stop” on mlaser, then clicked “Start”, then Laserbot began to engrave the same image again.
      Best regards,

  9. I have received my LaserBot and assembled it however when I complete the test my LaserBot it does not make an M. The Y axis is not moving at all.

    1. Hi, Nicole,
      You may switch the stepper motor driver for X-axis motor and Y-axis motor have a try. If the X axis moves okay but Y axis still not, I think the drivers are okay, the problem may be on the motors or motor wires. Then please refer to the suggestions in FAQ 4 posted in this link to check it.

  10. mLaser software v 2.4 is shown in Chinese language after installation, how can I change this?
    when downgrading to V 2.3 English language is shown.

    1. Dear Tom,
      We are so sorry to hear the trouble caused, please visit this link for instruction to Switch Chinese to English on mLaser.

  11. Hello,
    Did get the laser as xmas present, love it.
    Testing the laser gives a error, no serial port connected.
    And this is after a successfull update of the firmware on Mac.
    Firmware is Bluetooth updated , USB is connected on request after update.

    1. Hi Jan,

      What is the operating system of your Computer?
      I suspect that you may haven’t installed the Arduino driver on the Computer. So when you do upgrade firmware, you may have chosen the wrong serial port.
      Could you please take a picture to show the serial port in the drop down list detected by the mLaser software?

      For further feedback, please kindly send email to, thanks!

  12. The laser engraver works great. Easy to put together and fun to use. However it is only engraving on certain types of wood and not at all on others. Am i doing something wrong????

    1. Hi Anthony,

      What are the other wood you use but can’t be engraved with the Laser? Have you tried focus the Laser?
      Besides, on the mLaser software under engrave option, did you choose the Wood?

      1. It works really well on Alder but having trouble on poplar. It is on wood. How do you focus?

        1. Hi, Anthony,
          You could adjust the focal length of laser through rotating the knob on the laser head until obtain the minimum laser spot size. You could refer to the video tutorial “161018 Software toturial of laserBot(English)” on 01:29 for more reference.

  13. Hi

    How about cutting with the laser wood, plexi, acryl, leather, alu, ?

    thanks for answer!


    1. Hi, T T,
      Please find the chart of Processable Material on this page for all the material which has been tested by LaserBot. Users could engrave the leather, but cannot cut it. For other material which doesn’t show on the chart, which means we haven’t tested them so we cannot provide related information for you.
      Best regards,

    1. Dear Anthony,
      Sorry it is beyond our supporting abilities to provide supports for software non-developed by Makeblock. We are afraid that you may have to figure out if CoralDRAW meets your needs, or you could visit our forum to check if there is any similar concerns like yours.
      Best regards,

  14. Love My Laser!! A little bit of a pain to assemble, but WELL worth it! Quality construction and easy to use.

    Thank You for a great product

  15. Can LaserBot cut multiple sheets of paper at the same time? If so, what are the settings.



    1. Dear Sukumar,
      It really depends on how thick of the multiple sheets of paper, and we are sorry that we don’t have this kinds of information.
      Best regards,

  16. I got the laserbot and couldn’t wait to put it together. I did and tested it and it seemed good. Then I noticed spots missing from my designs. I downloaded the square svg file to test it and it burns an acute angle instead of a square. I retighted the belts several times and can’t see how I can tighten them any more. It still burns an angle. What is going on?

  17. Hello. I have a problem with the mLaser software. Every time i close it and try to run/open it again, it starts in chinese. I have to uninstall and install the program every time i try to laser cut something. It’s really getting annoying after a few days, what’s going on?
    I have all the newest drivers, windows updates done etc. the computier on itself is fine.

    Ty for helping in advance. Greetings, Anže

    1. Also is there a program that i can use besides mLaser? I hate when companies try to develop their own software but is so poor it destroys the joy of being a diy guy. If you cant make a good software just use what’s alrerady on the market!!

      1. Dear Anze,
        We are so sorry to hear the trouble caused. It used to be bug that the opening page of mLaser is Chinese, but we have already fixed it. If you download the latest version of mLaser, the opening page will be in English. We will send you the instruction of how to change language setting in mLaser for your reference. Please kindly check your e-mail.
        We are sorry that there is no alternative software to use besides mLaser.
        Best regards,
