I'll look it up when I get home! Thanks
The 12v is the fan pwm controller from the 3d printer. The laser stats say 9khz for the frequency
Specification parameter:
Body size: long 50mm* wide 50mm* high 100mm
Output wavelength: 450nm
Output power: 2.5W
Modulation frequency: TTL can be modulated ,0v- off 5V open ,PWM frequency <9Khz
Working voltage: DC=12V
Working current: I<2A
Focal length: adjustable
Operating temperature: 15 degrees to 45 degrees C
It's "working" straight off the 12v signal but the laser won't 100% turn off which is leaving traces from movement
