The power output has fast dynamic response, accurate and stable power delivery, and precise reproduction of designs in engraving and cutting.

Equipped with three types of protective heads, it ensures cleaner edges when cutting materials of different thicknesses while being convenient for maintenance.

Maintenance is convenient, and the NEJE's specially designed lens protector, rated for 1600°C and featuring a special coating for 450nm wavelength windows, includes a double fan design that is easy to replace.

The top-notch Nichia collimated light source has a power 10% higher than that of similar products and an average lifespan 40% longer.

With the sophisticated lens processing technology, it features a smaller focal point, enabling more delicate engraving and finer cutting.

It ensures uniform symmetrical cutting in both X and Y depth of field.

The red copper heat dissipation system combined with double ball bearings allows it to operate continuously at 100% power.

The built-in intelligent program in the driver can dynamically recognize the working status and adjust the fan speed to effectively control the noise.

The multi-nozzle design makes it suitable for various material thicknesses.

Equipped with temperature feedback and super electrostatic protection technology, it comes with free after-sales service for two years with global warehouse shipping.

Engraving with Z axsis

NEJE E80 is equipped with 2 high-temperature-resistant (1000°C) protective lenses, which can be replaced. Pay attention to regularly clean the surface oil and foreign matter according to the actual situation of use. Oil and foreign matter sticking to the surface may cause high temperature to soften the lens.

NEJE E80 can use 2 types of air assist. a. Conical air nozzle in the inner cavity, this method needs to use oil-free and water-free air source, (Note: ordinary oil-water filters can only filter simply, not completely, and need to be cleaned regularly built-in protective lens) b. Stainless steel pipe air nozzle, this method can use oily water air source, easy maintenance, and can quickly clean the lens, the metal pipe needs to be aligned with the focus.

When cutting mdf, leather and high-density materials, it is necessary to add air assistance with a pressure of not less than 30psi.

The air nozzle must be aligned with the cutting port to blow off the carbonized material, otherwise it will be ineffective.

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.

Connect 24V and GND pin to 24V power, ensure the power adapter is sufficient, 3A-5A is recommended.

Connect TTL/PWM pin to your control board PWM output pin.

E80 driver has very high conversion efficiency, input 65W can output 24W optical power.

NEJE Moudle Switch and Test Board

Compatible with NEJE 3 Max (the motherboard model is higher than V1.1), only need to update the 24V power supply, the relay and valve control module are compatible, the temperature will be higher than in 12V mode, and there is no problem with indirect use. It is recommended to connect other devices through the control board, and it is recommended to use the device with Z-axis control, which is conducive to the full performance of the E80.

Although this module adopts internal air-assisted design, long-term use may not prevent dust or a small amount of smoke from affecting the lens. It is recommended to clean the lens with a clean cotton swab. Dust or smoke may overheat the lens and cause the lens to burn out. Re-acquire the lens Will delay your use.
