I still have a PI3 running Octoprint with camera. I do this for the camera and some Octoprint plugins I like for LED and heater control of my enclosure. Works fine.

I am using this https://www.amazon.com/gp/product/B00E0NTPP4/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

Wired like you have it strips and it works great!

Looking cool. Is there documentation out there on the file structure controlling the interface? I would love to play with customizing it but can't invest the time in figuring out what is controlling what.

Why two Pi's? It would only be one Pi3 handling it all.

I will be working on learning the RR_STATUS capability and look into creating a script that posts those queries and manages LED's upon results.

Nice work on the Push; But I agree the API would be sweet and open up a bunch of capability.

@kraegar:

Personally, rather than support for a single notification service, I'd rather see an API for pulling data from DWC. So we could poll the data its already displaying without generating more gcode for the duet itself to worry about. (Temps, file progress, etc)

Then it'd be trivial to use a PI or similar to do stuff with that data - push notifications, light up LEDs, turn on/off a webcam, whatever by reacting to data pulled from the API.

(If such an API already exists, I haven't found it referenced yet)

Might be better to just offer triggers to another board. Which is then tasked with the LED control. Addressable LEDs can use a lot of resources.

I would like this since I run a Pi3 with camera on it to serve the Duet Wifi, video. I am also setting it up for the LEDs, enclosure heater and filament dryer controls.

Steppers are not defined 12v or 24v so good to go in both.

@dc42:

You can connect VCC of that relay module to +5V and IN1 to PS_ON.

Thanks! Thats what I thought. Should I gnd it to Duet WiFi also?

So this looks good to go then?

What about mechanical relay like this one? https://www.amazon.com/gp/product/B00E0NTPP4/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1
