If I understoo d correctly PWM turns on the laser only a small amount of time to get a percentag e of the power.
And the pot still determine s the max output power. Which means that I need to connect to a PWM contact shooting laser.
It is important to keep the Pulse Repetitio
n Frequency below 20kHz (to protect the laser switching electroni
cs) but I have had no problems connectin
g the 57CNC’s 5 Volt PWM signal directly to the TTL(L) input of my CO2 laser, although I did hardware invert the signal as described here;
