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!

I am looking to try setting up my super volcano with 2x 40W heater cartridges and 2 thermistors rather then the stock single 80W heater cartridge and thermistor.

In theory this would allow me to have 2 zones of heat in the hot end, an upper zone and a lower nozzle zone. The upper zone should regulate a higher temperature than the lower zone to help heat the filament faster while the lower heater would regulate a more consistent and lower temperature at the nozzle. For example, I would want to stick to 235C on the lower heater while running 260C+ on the upper heater.

This may or may not work, but IMO, it's worth trying. The first issue that comes to mind is the 2 heaters will fight each other. The upper will run more because of the higher temperature, and cause the lower to run run less, but under load, the lower should increase power to maintain the nozzle temperature.

Second to this would be multiple hot ends in series with heat breaks separating the heat blocks slightly in order to get true multiple zones, But still requires multiple heaters on a toolhead. For example, adding a V6 after the Super Volcano.

While I understand the physical connection of this to my 6HC, Im not exactly sure how I would configure the firmware to control this. Im even less sure of how I would tune something like this as the heaters would always fight each other and both heaters would need to tune at the same time.

Im interested in hearing others thoughts on this and if Im just totally crazy.

@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.

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-dsfnode module. 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-dashboard and node-red-contrib-fs-ops in 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
You could put the URL of the first camera in the normal DWC camera configuration and the URL of the second camera in the section that says something like "URL when image clicked"

Thats a good short term work around!

@Martin1454 said in Multiple Web Cameras:

Maybe you can run OBS stream, either on another device - Or if you have a duet 3 with an RPI, then on the RPI it self - That should be able to merge the 2 streams

I have not heard of OBS, but I will look into it and see if it could do this. I dont want to run anything too heavy on the Pi, as it will already be serving the 2 camera streams as well as taking to the 6HC and running NodeRed.

@TLAS said in Duet Web Control Plug-in Development Template:

I took a stab at the update yesterday and think I’ve mostly got the hang of it, but it got me thinking - why not create an empty ‘template’ plugin with some good comments to help those who haven’t used the vue framework before? I think it would help pull more people to contribute who have other web experience.

This sounds very useful for someone like me! I can usually get something working if I have something to build off.

I have done quite a bit of searching, but Im umable to find a way to display multiple web camera streams in DWC.

My setup includes a wide view and a nozzle view and I would like to switch back and forth between them. Currently this is the only thing Octoprint doing for me.
