How to choose professional laser equipment for engraving, cutting and drawing

When you are looking for an engraving machine, we recommend that you consider your needs: cutting, drawing, engraving?

a cheap laser engraver & cutter?

Many users only pay attention to laser power and area, as well as price and video when purchasing products; however, they often purchase unsatisfactory products. At present, more than 90% of the engraving machines in the market are products developed based on the GRBL open source solution. The origin of grbl is CNC, which is used for CNC control of motors. Many businesses avoid the development process and directly use grbl for laser control. It can bring very low cost because it is no need to develop a control system. Although GRBL is a well-known control system, it has many disadvantages in controlling lasers. For example, the laser power is constant during the acceleration and deceleration of the motor, but different speed may Causes different burning ”denseness“; slow speed when sculpting application, although the video can speed up so that you can not see the problem; cannot reset and sensor protection automatically, can not ensure the safety protection during laser work; Adopting acrylic structure, it is easy to be damaged during transportation and when use, and easy to deform over time, resulting in poor mechanical accuracy and short life. They use a second-hand cheap laser that is exposed and simple to assemble, without reliable cooling system, process standards, expertise and technology; What’s more important is after-sale accessory support and Warranty;

Is the larger area better? (T-shaped structure)

The T-shaped structure is supported by 4 bearings. At present, some companies can support 20cm wide area. This is of course attractive, but for the T-shaped structure, the larger area will cause mechanical instability. When the laser moves at high speed, it will cause the mechanical structure to be very unstable. It is not a difficult technical to make a large area and does not require any cost, but it will greatly reduce the engraving effect. The system cannot make the laser move stably at high speed.

About NEJE Master Laser Engraving,Cutting, Drawing Machine!

NEJE Master machine is a full-featured engraving, drowing and cutting machine, with comprehensive craftsmanship and capabilities, and extremely portable desktop use.

In the key structure, we have eliminated the acrylic structure, using CNC composite materials to improve mechanical accuracy and durability;

The laser uses key diode capping technology, passes standard process and aging tests, ensuring that you receive long-term use without failure and a lifetime of 10000-20000 hours.

The control system NEJE uses a dual MCU architecture to support NEJE’s own development and continuous updated control system. The characteristics of the NEJE control system are simple operation and safe use, a lot of process optimizations have been made specifically for laser control; New ways of use are continuously created, such as NEJE scanner, cloud material library, supporting sensor protection IC, GRBL open source software and Z-axis extension driver IC, also executing G-CODE for professional users.

Based on the NEJE control software, the NEJE laboratory team continuously develops algorithm technology for laser processes, bringing more value to users.

The laser module power is not the higher the better

The NEJE laser module is developed according to the actual process requirements. When you choose a laser, it is not necessary to use more power. For example, the NEJE 405nm 3500 module has a high power of 405nm and a very small focus. The short wavelength of 405nm is easier to Material absorption, all effects and precision are the highest. Its process features are high-precision engraving, gray-scale engraving and high-precision drawing images. The disadvantage is the average speed; 7W modules are good at high speed because of their light weight, small focal length, small focal point, and high power. Deep engraving, suitable for engraving logos and patterns; 20W module has a small focal point and high power, but is relatively heavy. It is good at slow depth engraving and cutting wood and paper pieces less than 5mm thick; you need to consider this according to your actual needs Several modules.

About NEJE Master Mechanical

The actual mechanical area of the NEJE Master engraving machine is 170mm * 170mm. Software will be upgraded later to adapt.

NEJE machinery uses composite materials and CNC technology, the pads are designed with silicone, and the 4 feet have fixed hole design, which guarantees accuracy and stability. The technology of other manufacturers’ acrylic materials is laser cutting, the accuracy is poor, and over time, the acrylic will bend and deform, and the accuracy of the machine becomes worse and worse.

NEJE 12V LaserModule Tester.

NEJE 12V LaserModule Tester V1.0 will be released. It can display the laser working temperature, you can set the PWM signal manually, you can receive 2Pin 3.3-12v TTL signal and display the PWM.

  4. AliExpress Shopper

    Good, But I need more powerful laser machine.
    If you(seller) can make more powerful laser machine, please do it.

  5. G***o

    Good afternoon! Everything came and works, I’m happy. Seller recommend

  6. H***k

    Great ~ really favorite dish

  7. AliExpress Shopper

    Items arrived surprisingly quickly! The product was super easy to use.

  8. A***v

    I think it’s one of the best machines. I think how to remake under a large field. + I ordered another lens I will check.

  9. C***s

    A good desktop computer to start. The laser output is not really 20w but cuts thin wood. The package arrived well and quickly to Mexico.

  10. AliExpress Shopper

    Goods have been well packed and received well. Power controll in the important lower range is a bit too coarse, and the rapid movement of the head makes the whole machine jump around. Need to hold it down during operation or find other means to fix it more stable than it comes originally. Data in enclosed manual are totally wrong, with these mSec times all material gets destroyed. Instead of e.g. 25 I need to use only 2.5 but the setting allows only a straight number 1,2,3 4 etc, what is a bit difficult, as have to work also with reducing the Power to come to workable figures.
    With some modifications it is a good thing 😉

  11. d***i

    Rapide super produits

  12. D***n

    All as in the description! It was a little less than a month. Immediately began to grow, a tree, the skin burns with a bang. Metal does not take, no, even with a marker, even with thermal paste. Painted metals paint purely burns. Cutting did not try again, later I will add a review. The toy is cool, but not for commerce. I took myself as an additional machine for engraving on leather and wood, as I am engaged in engraving in general, sometimes such orders are received. With all discounts and coupons cost almost 11680r.

  13. P***S

    Perfect. Conform to the description. Works very well.

  14. AliExpress Shopper

    working good till now, but 20W lens can’t focus enough.

  15. i***r
