The difference between NEJE 3 PLUS and NEJE 2S PLUS
- Compared with NEJE 2S PLUS , the operating experience is greatly optimized, the low-light display of laserGRBL and lightburn in GRBL mode is increased, and the low-light intensity.
- More abundant functions are: added M8, M7, Door functions, and all are compatible with NEJE software, laserGRBL, Lightburn
- The top 32-bit processor has replaced the NEJE 2S PLUS two The chip processing solution is more reliable, support OTA upgrade in NEJE mode, NEJE continuously upgrades software and firmware Provide.
- 【Top engraving speed】Just fit on a desktop with a width of 600mm, and the left side of the machine is not limited by the size of the material. It is suitable for processing large area materials. Under the protection of the MEMS vibration protection sensor, the engraving and cutting processes can be completed at the same time. The X-axis motion module is only 120g and is driven by a 40mm thick high-performance stepper motor, bringing a faster engraving experience than the gantry structure, 3400 x 5600 pixels, engraving accuracy: 0.075 mm dot pitch, 339 dots/inch. The whole machine function test requires only 4 screws to complete the installation.
- 【Top engraving capabilities】 The laser beam is formed by combining two high-power laser diodes distinctive technology. The minimum focus point reaches 0.04×0.06mm(A40640 module). 12w pulse real pulse output. It can directly engrave clear grayscale on the stainless steel surface. Support NEJE advanced laser module, Built-in fast intelligent drive, temperature feedback can be timely, and intelligently adjust fan heat dissipation. Safe and quiet to use.
- 【More materials, clearer】 Wood, MDF, leather, paper, cotton, etc. are all supported. 8mm plywood only needs air-assisted cutting once (A40640), and the cutting is very clean. Can directly engrave stainless steel, glass, transparent acrylic and so on.
- 【Portable professional control software]】32-bit control system, the fastest speed can reach 200,000mm/min, supports LaserGRBL, Lightburn, NEJE Win software, NEJE APP (Android phone, iphone, iPAD, macbook), you can change it by taking photos with your mobile phone or selecting images from the album To complete the work quickly, NEJE provides free software OTA upgrade services.
- 【Perfect after-sales service]】The whole machine is guaranteed for free for 2 years (laser module: 2 years and 20,000 hours warranty), and vulnerable parts are shipped worldwide within 24 hours.

M7 relay expansion accessories, can be used to control AC or DC power supply smoke exhaust system, can also be used to control other circuits, used as M8, there are safety risks when operating high-voltage circuits, requiring professional operation; M8 valve expansion accessories, can be used To control the air compressor switch, neje 3 supports accessories expansion, but the relay module, air valve module and Door need to be purchased separately,not included in the product list.
About air assist
When do you need air assist
Air-assisted engraving or cutting can only be used for engraving or cutting that produces more carbonized substances. Generally, the depth of engraving is less than 1mm, and the cutting of plywood less than 2mm does not require air assist. A small fan can be used to blow off the smoke generated by the engraving. Air assist is not recommended when engraving images, and adding air assist at this time will destroy image details.
What kind of air pump is suitable for cutting
The main meaning of air assist is to blow off the carbonized material produced by cutting, and the general oxygener and electromagnetic inflator have almost no meaning. only the pressure of the oil pump and air compressor (0.4-1.5mPa) has the effect of blowing away the carbonized material. but it should be noted that the air of the oil pump contains oil and cannot be directly used for the air-assisted module of the closed cavity, otherwise the oil will contaminate the lens, resulting in power drop or damage to the lens. The air pressure of the air compressor can be used for a short time with the closed cavity, but When used for a long time, the water-containing gas will contaminate the lens, cause the power to drop, and even damage the lens.
How to add air assist on the A40640 laser module
The NEJE A40640 module is an adjustable focus module. For the consistency of testing, the NEJE factory adjusts the module to 55mm focal length by default. This focal length is suitable for cutting thicker materials. This focal length is generally not commonly used. When you are suitable for the first use of the product, it is recommended to use a flat-head screw to adjust the focal length to about 30mm, which is 1-2mm away from the light baffle. This focal length has a very high focal power density and can directly engrave grayscale stainless steel images gray-black stone and other hard materials, NEJE A40640 can directly engrave 3D hardwood and other materials, and does not require air assistance, due to the high energy density design, A40640 can directly vaporize general wooden materials during the engraving and cutting process, so it is also unecessary to add air assist.
