LaserGRBL Software – first launch

LaserGRBL Software - first launch

To start using your laser machine you need to connect to it your computer via a USB cable. Once connected, we run LaserGrbl, select the COM port, to which our laser is connected, and click the “Connect” icon.

LaserGRBL checking firmware

If the connection is successful you will see the info about your machine and its firmware.

LaserGRBL - connect

For the correct operation of all the machine elements and correct sizing, you need to adjust the configuration of your machine. To do this, select GRBL Configuration in the GRBL tab.

GRBL configuration

Here you can configure the GRBL firmware or import the existing one. For this we select and import the file with the configuration of our machine. It is also possible to enter the speed, acceleration, steps and other parameters manually.

In the left bottom corner we set the laser movement speed. The right runner adjusts the step size of the laser head when you click the movement buttons.

LaserGRBL movement

Next, we test the carriage movement using the arrows in the left bottom corner. For resetting we click the Home icon (this function is activated if you have end switches installed).

The next step is to prepare the work field. For this we place a piece of wood on the work table and check if the machine responds to the ON and OFF commands.

LaserGRBL - worktop For this there are several buttons on the bottom bar tool.

«Focus» turns on the laser for focusing (3%).
«Blink» is a short pulse (10%).

It is important that you follow the safety rules when operating a laser. Wear your safety goggles!

Let’s laser our first image.

LaserGRBL open file

Having placed the workpiece on the work table, we import an image (let it be the ENDURANCE logo). We click the Open File icon in the left (левом??) upper corner.

LaserGRBL importing file

LaserGRBL - vectorize the image To speed up engraving we convert the image to a vector file. As a result we get an outline image of the logo. Now in the Vectorize options we check Smoothing and enter 10. We do it to remove unevenness in small-sized images.

LaserGRBL - image processing

In the same window we can select a filling mode. There is a wide choice of options. So you can choose those you like most.

Now we click Next and set the maximum engraving speed 700 mm/min. The maximum speed value depends on the engraver type. You might have a different one.

In «Laser options» we change the laser start command М3 for М4. You do it only once. The program will remember this parameter.

LaserGRBL -laser speed

Next we choose an image size to our liking. Our choice here is  94 by 94. Further on, we create an image. The logo image we have selected before is displayed in our work field.

LaserGRBL - run

The next step is to position the workpiece for engraving in one corner of the work field (table?). After this we run the programe (by clicking the button in the upper left corner). Устанавливаем материал, на котором хотим получить гравировку, в угол рабочего поля (или рабочего стола???) и нажимаем на «пуск», в левом верхнем углу.

LaserGRBL Endurance lasers

After the start of the engraving process, you can watch its progress and stop it on an emergency basis if needed.

While using the LaserGRBL software, we have not noticed any bugs or fails. So, we can tell that the program is highly reliable. All its functions and options are user-friendly and trouble-free.


That’s about all. In this article we’ve reviewed only part of the program features. If you are interested in more information, please, comment. We can give more details if needed.


Here we stop and wish you successful experiments and tests!

And one more important thing: don’t forget about the safety rules when working with the laser!
