NEJE Laser Duet 3 wiring
-
so am i supposed to wire the laser to the 12v and Ground also or just the out9, 5v ext and ground connection by the micro sd card? Or can I wire the laser to the out9, 5v, ground and use the 12v power supply that came with the laser.

@thechainring Have you seen this post?

yeah i read that and wired the laser to out9 5v ext and ground but the laser didnt work near is strong as when I powered the laser by it self with the power supply and adapter board. Am is supposed to power the laser from a 12v power supply or get the 12 volts from the duet board.

here are the boards included with the laser. I guess i am going to test it while supplying the 12 volts

@thechainring From the wiki
Connect the laser GND, 5V and PWM wires to the appropriate pins on the Duet 3. The 3-pin 5V PWM output on the Duet 3 Mainboard is behind the MicroSD card holder. Connect the PWM wire to the 'out9' pin.
I'm not sure whether the Duet is providing enough current via the onboard 12V. Probably best to just use the Duet to control PWM and get your power from the external adapter
