Hi all,please help me connect my 15w laser to CNC 3018 Sorry for my English :) My board is woodpecker 3.2 updated to 1.1f,Software laser grbl. My laser: Output wavelength: 445nm~450nm Output Power: 15W ,average 8W TTL frequency:0V(OFF) 5V(ON),PWM frequency:<9Khz Laser light:Blue Violet Light Working voltage: DC=12V Working current: I<3A 15w laser My problem is: after connect to board Laser burn if isLASER GRBL program open or close all the time is on PWM connector 7.82-9V

2 So that i changed PWM from board but orig.PWM for laser was not good for my laser. 3 My question is: 1)how change frequency for my laser (i need 9hkz) 2)after change frequency is this 9hkz on (+12v,GND) laser connector too but only spindle motor? 4 Thank you for help.
