Hello I have some 405nm Sony and Nichia laser diodes ranging from 400mW to 7 W.
I want to make some greyscale engravings or markings onto paper using a small desktop CNC using GRBL.
Curious if anyone knows how to make a PWM/TTL laser driver circuit, how can I make one?
Would be using a micro controller such as an Arduino or ESP32.
Thanks for any advice.
