Control by Computer

Before you can use a computer and laser facility for engraving, you need to install a facility driver which allows the facility to communicate with the computer, furthermore, you need to install application software on your computer so that you can start your engraving. The same situation applies to the Laser Engraver, you need to install the USB-Serial driver which allows the Laser Engraver to talk to the computer, and you need to install the engraver software to control the Laser Engraver. NEJE DK-8-KZ, DK-8 PRO-5, DK-6 PRO-5, JZ-5, JZ-5-T, DK-5 Pro-5 engraver comes with a 1GB micro SD card, the files on the SD card are including the USB-Serial driver, engraver software and few JPG photos as shown in the figure below. The software is compatible with Win XP, Win 7, Win 8, Win 10, system.


We will use the gray cardboard to carve as an example to explain, please follow the instructions to do your operation.
>> Obtain a desktop computer or laptop computer (computer operating system requirements is WinXP, window 7, win8, win10);
>> Obtain a USB rechargeable head (5V1A) (Apple, Samsung, Huawei mobile phone head can be, Support 5V1A or more);
>> Open the packaging, remove the fixed tape and pearl cotton on the machine;
>> Adjust the focal length of the laser, factory default settings the focal length of the gray cardboard, there is no need to do any adjustment. If you need to carve the object in different thickness, you need to place the object in the engraving platform and adjust the focus manually, when in the first operation, it is recommended to use gray cardboard (in the package list) to carve;

The method of adjusting the focal length as follow:
1: Fixed the surface of the carved objects at the level of the bearing table, put on the focusing glasses( sent in random) (maybe will not adapt it at the beginning, just to be used as the focus), rotate the focus head manually, shown in the figure:
Adjust laser lens NEJE

2: Observe the light down to the surface in the smallest point of the object, when the rotation to the smallest point, indicating that the focal length has been adjusted, note that the smaller the focus adjustment, the image engraving effect is finer, if the focal length is not adjusted, there may be no image to be carve;

Safety precautions:
1. Our machine certified to CE and FDA certification, the radiation values far below the EU and the United States standards, please rest assured that use;

What materials can be carved, how to fix materials?

Objective engraving material: “Smooth, Organic, opaque, Non- flame- retardant material For example Wood, Gray cardboard, bamboo, Leather, etc.

Unsuitable engraving material: ” Those materials unable to burn &focus“ For example Pure metal(without coating), transparent plastic, White paper(Astigmatic), PP plastic, etc.

Fix the object to be carved with a silicone pad and rubber band or other auxiliary tools.

All downloadable files are mirrored from neje.tool


  1. Do not engrave on a reflective surface.
  2. Neje comes with a board marker if you want to engrave on a white surface.
  3. Suggestion: Try using a non-transparent tape. You`ll like the print more.
  4. Don`t be like a cat. You will never catch the laser dot. Machine laser energy is not that huge enough to damage you if a hand or other part of the body stays in the curving scope accidentally during curving, but, you’d better be careful since it’s an abnormal operation of the machine.
  5. Keep away from children
  6. Keep away from dust. Avoid prolonged exposure to dusty environments. Put it in a safe place to avoid dropping. Is fragile. Add a little lubricant on the moving parts if you don`t use the machine for a long time (Lubrication is good for many reasons. But do not lubricate it too much).

Nekem az a gondom, hogy nem tud kommunikálni a laptopommal a neje, mert az egyik program azt írja ki, hogy nincs csatlakozva, a másik meg becsukódik mielőtt csatlakozna....amúgy, minden oké, beveszi a képeket is, és a betűket is, csak épp a komunikáció hiányzik a számítógéppel :( . Ilyenkor mi a tehendő és a probléma hogy orvosolható ? (laptop frissítés után csinálja ezt a neje :( ) . Köszönöm a választ, üdv: Zsé.

You can`t simply connect the engraver via Bluetooth with direct connection. You need an app. But this can happen only with Android or iOS. For PC you must use cable.

(YYYY-MM-DD) dd 2020-01-14 03:22:41

I have the Master 7w and 20w that I use for a craft company I own. Other than the predownloaded G-code files, I cannot get this software to accept .dxf files from Inkscape or adobe illustrator. I cut custom shapes and do custom engravings so I kind of need to figure out why it will not work. And I was a little disappointed when I noticed I cannot find anything online about increasing the cutting area. Any help would be better than none. Thanks.

I noticed in the latest couple pf updates for the NEJE DK-8-KZ, that it was stated that the area that could be engraved was 100 x 100mm but version 4.7.1 still only engraves approx 37 x 37mm.
When will the software be updated to engrave up to 100 x 100mm??

when sending gcode to neje master 7w laser via neje 4.7.2. how do you turn the laser on and off?
it ignores M3 and M5 as well as M4
when controlled through any other software, it accepts M3 and M5. but not when you use the NEJE 4.7.2. software. how silly.

It's more portable than you think it is. The drivers, although I thought it would be a pain in the butt, was not! It solves all your engraving and DIY needs.
