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 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;

  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).

I have given up on using this machine. It will not allow me to translate from Chinese/Russian to English and doesn't want to connect. It was working with a lot of weird actions on my part but doesn't work at all now. What do I do?

I was able tofollow your instructions and get my engraver working again. However, at first it looked perfect, but subsequent attmepts are skewed on the item. Either on an angle or like it smaller on one end. It's probably an adjustment but I can't seem to get it to look better. thanks

All the NEJE Windows software versions (all up to year 2019) are smaller than 1.7MB, they run nicely.
All the NEJE Windows software versions (all from year 2020) are larger than 4.6MB and they give error right when trying to run.
Why is that?
