      Hi,

      I have recently ordered a CO2 laser engraver and looking to convert it to DuetWifi. However the recommended 74HCT02D is quite a challenge to get where I am now.
      The power supply is similar to K40 with pins as follow:

      I am wondering if I can use a fast Optocoupler such as TLP521 (Data) to convert DUET2 5V fan PWM to the 5V PWM for the laser. Then some 24V relay to pull L to GND for activation?

      Thanks.
