ramps 1.4 3pin ttl laser connection diagram
hi 3pin ttl laser available.ramps 1.4 which pins should I connect ? I use translation
If you need 5V ttl signal to enable it any output pin will give a 5v signal. But only 1 pin gets controlled. Other pins might be gnd/12V? That is at least how my laser works.

This is my laser. this is my card ramps 1.4. to which pins should I connect? I use translation
At least same pins as for me. I have added 12V to fan so I can enable laser by enabling fan. PWM pin goes to a free pin. When I enable 12V I see a weak light I can use for optimizing focus. When I enable pwm as well I do not want to be in same room for safety. That is the pin number you need to enable the laser.
