thanks guys,

So, you use the fan output to control laser power and on - off

my fan are 24V, so i need a resistance…

@cgcafer that laser looks nice...it's a 15W.... but it's the real power? It's a lot for that price. Do you have some videos?

Hello,

I would buy a laser diode 6W for engraving, to mount on the head of my 3d printer selfmade with duet Wifi.

But I'm not very sure if I can connect it.
I'm using 24v on duetwifi and this is ok for the laser, but it need a 0-5V input for power regulation (I can use an external potentiometer ) and I don't understand how to connect other cables to turn on and off the laser.

I think to need to use the laser at minimum power to simulate and center the figure, and at high power to engrave.

the laser and instructions are in this link : https://optlasers.com/en/jmsblog/aktualnosci/51_plh3d-6w-xf-laser-head

could someone help me to do this?

thanks a lot…

bed levelling option is very nice.....

Hello all,

I'm thinking to drive 3 motors Nema17 to lift Z using 3 screws. How I can wire them? I see onboard (duet Wifi only) I have 2 connector for 2 motors, but how I can connect the third?

Motors are 2.1A each…maybe i need reduce the power?

thanks for asnwering.
