Main Features:

[Accessories system update]

  • Specialized Motherboard with 32Bits MCU It could preprocess 32 instructions, support baud rate as high as 921600, more powerful!

[Safety protection]

  • Active Position Protection There is a G-sensor on the motherboard, if the machine detects unauthorized movement, the laser beam will stop. When the engraving machine is displaced or tilted, it will automatically stop the laser to prevent damage to the target from the laser;
  • When the engraving machine or computer crashes, the laser will stop working immediately to prevent continuous fire.
  • Exposure Duration Detection and Limitation If the laser engraver is under control, but users forget to operate and keep the laser beam working, extra safety will be cut off in case the motor stops moving, to prevent fire.
  • Flame Detector + Buzzer Alarm 5. Emergency stop switch for an emergency.    (99% of engravers on the market do not have security protection features)

[Wider power range]

  • Laser power range could be S0 - S1000, compared to 8bits desktop laser engravers, which only have 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, and the resolution of the engraved real image is clearer, that the 8bits high power laser engravers could not do.
