I bet as a hobbyist to reach 4000hrs can take ages.

Just wonder how to make laser to cut under mach3 with different power. laser power supply adjusts the power by PWM modulation of ttl signal.
So if I understand correctly, if I set up different spindle speeds for different paths there is a way to control laser power output. As I never controlled spindle speed under mach3 I have very vague idea about it.
