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 a 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 using, 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 a 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 a 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 technique 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, drawing 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 continuously 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 lightweight, 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. The 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.

    The cutter is absolutely cool. The truth is written that it is not engraved very much and it is true. I must say that rubber it cuts not in the best way. But the rest is quite good. And the software is good and the cutter itself is convenient.
