Description：
Master engraving machine is a portable engraving machine with simple installation, safety and easy operation. It has built-in sensor accelerometer. When the machine tilts, it will automatically stop laser work and protect from laser damage. At the same time, it supports NEJE control software and GRBL software, which can not only enjoy the simple portability of NEJE software, but also support the operation fun of GRBL open source software; it supports the dynamic control laser module developed by Neje, which can support PWM power regulation, low light brightness regulation, laser temperature induction protection; it also supports different power lasers. The master 7w specializes in metal engraving and deep wood engraving and cutting.

Main Features:
Built-in sensor protection:
Dual MCU: one MCU for Support NEJE Controller ( Windows & MAC ), the other for GRBL Controller
OFF-line working:
150mm x 150mm working area, 160mm x 160mm in GRBL mode:
Limited switch design:
Compatible with laser modules ( 3500, 7W, 20W)
Z-axis, fan, safe key button support
PWM laser power adjustment
Cloud gallery service
Image and text edit
Easy position
Repeat engraving
Support BMP, NC ( G-code ), DXF ( CAD ), etc.
NEJE scanner ( photo share )

Applications:
● It supports metal engraving including alumina oxide, copper and other non-reflective materials, depth of engraving ( 0.5 – 3mm wood ), thickness of cutting ( 2mm )
● Support engraving materials: wood, gray paper, leather, bamboo, blackening plastics, rubber, alumina oxide, copper, etc.
● It is not possible to directly engrave the metal with strong mirror reflectivity, which may cause injury to the operator or burn the laser

Items can be carved including: alumina oxide, copper, mahogany, bamboo, paper cards, ivory, leather, flammable plastic, PCBA, etc. Please take notice that the laser head is easily-consumed products, so we promise to supply again within three month if the laser head is inhuman damage. So if you laser head is inhuman damage, please do not give negative comment, thanks for your support.

Notes:
1.When the machine is working, it is recommended not to look directly at the laser head, and not to operate the laser head directly by hand
2.Laser diode is a sensitive component, pay attention to prevent electrostatic damage ( product includes electrostatic protection design, but there is a certain probability of damage )
3.The laser module warranty time is 1 year
4.The controller board warranty time is 3 year
5. The manual and CD-ROM are not included, software download and use help by neje wiki service
