Ok - what I want is a flow that can look at the image from my Centauri Carbon webcam and determine if there is a previous print still sittng on the bed. In my mind, this would seem to be a useful job for an Awful Idiot piece of image recognition software. I view whats going on via an IP address h…

As Bambu already has this feature, the best flow recommendation would be to buy a Bambu.

Perhaps you could use Teachable Machine for this? watch this : https://youtu.be/-kBCq-M3gSA?si=DvZk3sfspl5hJnKW

[image] bakman2: Why would you print something and not remove it from the bed once finished...? Because it may take 3 hours to print. One does not sit around waiting for it to finish. I suspect that anyone with a 3D printer will have done this at least once.

But very few of us have done it twice in the same day :slight_smile:

True. I think I have done it only once.

Are you running headless? Then you may need to provide the arguments for a headless browser, i have a working flow somewhere, can provide it later.

We have wormsign :slight_smile: [image] Got a few errors to start with and then worked out I needed to cd to my .node-red/ folder and run npm i puppeteer and then it worked :slight_smile:

Having set width to be bigger I'm now getting enough image to display webcam window [image] Unfortunately, as you can see, I get a connection failed message This is exactly what happens if I open a real browser tab on the ip address but after about 5 secs - the webcam image appears [image]

I'm failing at the 1st hurdle - using puppeteer to try and get a screenshot of the webpage is crashing NR

Never had a lot of success with pupetteer in NR. I think the last time I did this I had to use an exec node and use puppeteer natively
