Hey Chris does your power control work through PWM? I got the same laser and its either on or off. PWM signal doesn’t change from like 200mV until i set it at S255 then it goes full 5V.
Sorry for the late reply… I’m sure you have this working by now. For the sake of others who may have the same question, yes, when properly configured, the signal is a pwm signal that can control the laser power.
I’m just finishing up my 3rd machine and have to review this information to replicate the setup I have on my previous build.
