Ortur Laser Master 2 S2 LU2-4 SF Engraving Machine


-Specialized Motherboard with 32Bits MCU

It could preprocess 32 instructions, support baud rate as high as 921600, more powerful!

-The Most Advanced 32Bits Laser Engraver Firmware
Ortur laser master firmware, smarter, faster, higher precision and easier to use.


-Laser power range could be S0 - S1000, compared to 8bits desktop laser engravers, which only has S0 - S255, Ortur Laser Master could control laser beam more accurately, could even use the high power laser unit to "draw" a picture on paper , that the 8bits high power laser engravers could not do.

-Engraving speed could be as high as 5000MM/Min.

-Active Position Protection
There is a G-sensor on the motherboard, if the machine detects unauthorized movement, the laser beam will stop.

-Laser Beam Safety Guard
If your computer system halted or USB cable disconnected, led to that the laser engraver stops moving, the laser beam will stop, to prevent fire.

-Exposure Duration Detection and Limitation
If laser engraver is under control, but users forget to operate and keep the laser beam working, extra safety will cut off in case the motor stopped moving, to prevent fire.

-LaserGRBL ( free software ) supports Windows XP, 7, 8, 10. LaserGRBL is the most popular carving software in the world, could import different format images, you could editing in PhotoShop, Inkscape, CAD, etc. and then connect to the engraver via laser LaserGRBL for engraving and cutting.

-LightBurn ( not free software, ) supports Windows, Mac OS, and Linux. It's the most popular paid carving software in the world, very easy to use.
This laser engraver supports PWM mode.

-Pre-assembled parts, just need 10 - 20 minutes to install the machine.

-390 x390mm large engraving area.

-Aluminum profile frame + structured cabling, solid structure, smooth operation, attractive appearance

-Synchronizing shaft mechanical structure, avoid out-sync on two Y rails, during full speed engraving.
