OXlasers 4W 450nm Focusable Engraving Blue Laser Module for CNC 3018 3018pro with PWM (4W)
19 Consomer Reviews
OXlasers 4W 450nm Focusable Engraving Blue Laser Module for CNC 3018 3018pro with PWM (4W)
  • ORANGE HEATSINK, focusable, can cut max 3mm plywood in a very slow speed and 3-4 passes, can cut 0.1-0.2MM copper wires and stainless steel wires
  • Output: 4W, Wavelength: 450nm, PWM: 0-5V , <18Khz.
  • Please pay attention when connecting wires : RED wire=12V+ , BLACK wire=GND -, Yellow Wire= PWM,PWM: 0-5V <18khz
  • Wrong connection of the wires may damage the driver board and the diode
  • This laser has rectangular dot, not a round dot, so when you focus it to the smallest pinpoint, there will be a small line across the dot, so when you see it , dont worry, its normal, it won't affect engraving.
