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

I triple checked the cable. Position wasnt the issue.

Cable was, seems like shop made bad connection or strands broke inside. Used my own cable and all is good!

So I just got a IR probe and I think it is doa.

I have wired to the IN, GND, 3.3v of the Duet Wifi z probe plug, Skipping the MOD pin

It never lit LED on boot.

Meter reads 1.33v across the Vcc and GND on the DC42
Meter reads 3.33v across the Vcc and GND on Duet

The Z Probe monitor in the webcontrol read 608 and moves to 609 when paper is under it. No matter how high off board it starts.

Thoughts?

Thanks, I saw that and am excited over turning with screwdriver. What I have yet to find is the formula for figuring out what mA to start with. Like other drivers have you set a Vref based on max holding current * 80% * 1.x

So I guess since this is straight current then a good start would be 80% of max holding current???

So I have searched for a formula for setting the current of these drivers but can't find any. Do people use the TMC2100 formula?
