Hello everyone!

Maybe some of you have already tried yet, so I will ask. I would like to connect some kind of Laser module (eg https://ae01.alicdn.com/kf/H6f3913cf...b104d0059y.jpg) to MK3/4 + Rpi + TNGv2. There is only information, that can be controlled via "Interface Parameter: Support TTL signal controls power ". From the picture I can see, +12V, GND and PWM signal. I guess, that PWM is used for controlling, but without any info about parameters, like voltage or min-max duty cycle.

So, is to possible to somehow connect this laser to board? I mean, something like button/ Gcode Mx to really control the "power" via Gcode.

Thanks,
Andy
