NodeDSF : Interface nodes for Node-Red + DWC plugin (NEW V1.1).
-
I have been working on a side-project / plugin for a while called NodeDSF. There is the mandatory crappy youtube video showcasing some of what you do with it here : http://www.youtube.com/watch?v=Y6JZ-lblt5w.
In summary, it is a set of custom nodes for Node-red which interface with DSF (on SBC) and enable you to create your own event driven actions.
There is also a plugin for DWC which allows you to embed simple node-red dashboards into DWC.
The project is here : https://github.com/MintyTrebor/NodeDSF.
It's only just been made available today, so assume it has bugs etc (so far it has a test user base of 1
).I have attempted to write a wiki and included some examples on github.
I hope its of use!
**V1.1 Update - Connect to Duet boards directly **
I have enabled a new experimental Duet mode which enables a direct connection to Duet control boards (v2/3) running firmware v3+, so you can now choose to connect to DSF on an SBC, or Duet board directly. (I have only tested this on a Duet v2 ethernet board, but it should work for the other versions). Non Duet boards (eg LPC) with onboard wifi modules will not work due to session limitations; An SBC with DSF is still required for these boards.
The plugin remains an SBC only option. -

Fantastic work!
I am working on a custom filament feeder system for a large format printer and was thinking I was going to need a PLC to do the filament changing. This will work perfectly using the RPI running Node Red and integrate to the printer.
It will be a few weeks before I will be up and running but I will add it to my list of stuff to setup, but I'm sure this is going to really make a difference in my application.
Thanks!

Well, I couldn't resist trying this out. I said a few weeks and I didnt make it 24 hours. LOL Here are my observations.
This is on a fresh system sitting on my bench still. It is not connected to any hardware yet.
Duet 3 6HC mainboard connected to and powered from a 4GB RPI 4 running DuetPi-Lite. I installed node red and tested it out to work. I installed the
node-red-contrib-dsfnodemodule. No trouble so far.I went to import the example flows, thats where I had a few small stumbles. I had to install
node-red-contrib-uibuilder,node-red-dashboardandnode-red-contrib-fs-opsin order to have the flows deploy without error. While I figured it out rather quickly, this info may be useful on the readme of the examples.I tested the dashboard UI and I have the BL touch, Timelapse and my own System Control pages working.
Next, I tried to install the DWC plugin. This is where I'm stuck at currently. I upload the zip file as instructed, and it asks to install. I select yes and thats the end of it. No plugin appears in the list, and nothing else is displayed that I can see, but I'm rather new to DWC.
Im not sure where I should go from here, but I can provide logs if you tell me what to look for.

@adamj12b I suspect you may not have read the installation wiki pages
...You should review the node-red installation wiki page, it covers the additional nodes for the examples, plus also covers enabling node-red persistence which is required for some of the example flows.
Once installed the DWC plugin has to be enabled by going into the machine specific-plugins section. The plugin installation page in the wiki covers this. If the option to enable the plugin is missing then that may be an issue. Let me know. (FYI: plugins included with DWC by duet are in general settings-plugins, 3rd party plugins you add manually are in machine specific-plugins)

My apologies. I should have slowed down and RTFM... Im a little trigger happy with all this awesome new gear to play with.
Just as the instructions said, I needed to enable it under machine specific plugins. I was looking under general.
I got it all fixed up and set up my ui to match. (I cannot seem to insert a pic, so here is a link)

I will report back once I actually get some hardware connected and doing something.

@adamj12b Glad you got it working.
If you have not done so already, I would recommend enabling node-red persistence (its required for the time-lapse flow) as described in the node-red installation section of the wiki.

I have updated the nodes to V1.1 with a new experimental feature which allows connection to Duet boards directly - no SBC+DSF required! (see edited first post for details).

@MintyTrebor
would it be possible for you to make a video guide for set up? I'm a mechanical guy, and this software requirement stuff is kind of hard for me to wrap my head around. i have a duet wifi board and i uploaded the NodeDSF_Plugin folder but as far as node red goes i have no idea how to set that up. -
@Dakota - Hi. There are written instructions on setting up node-red in the NodeDSF installation wiki pages
...If you prefer video instructions for installing node-red, there are many already available on youtube, for quite a few different platforms.
The NodeDSF node-red nodes should work on any Node-Red installation regardless of platform (windows/pi/docker/linux etc).
Edit: I forgot to add. You say that you have a Duet Wifi Board - So can I infer that you are not using the Duet Board + SBC connected over GPIO configuration?... The DWC plugin does not work for stand alone Duet Boards. (please refer to the wiki).
The node-red NodeDSF nodes work for both standalone and board + SBC configurations.

@MintyTrebor
Your inference is correct, I don't currently own a R-Pi (though I would like to get one at some point). So that's where I was getting really confused in the wiki since most documentation seems to point to needing a separate host like an R-Pi. Then I've been trying to figure out how install it without since you said the v1.1 could do so.
