        @adhanabal the PWM and ground connections are as you have shown them but you will need to leave the 5V pin on the Duet not connected. Connect the laser 12V and ground pins to a 12V power supply.

          @dc42 if I connect with 12v and ground I'm getting under voltage ⚡ warning. Should I use separate 12v power supply?

            @adhanabal That's what he said:
            Connect the laser 12V and ground pins to a 12V power supply.

            People with such a short attention span shouldn't play with lasers... just my 2 cent
