@stuartofmt thank you! That was the missing information I needed. I have it installed and running. Now to test some gcode…

@stuartofmt Hmm, not sure if this is right but it pauses 2.7 seconds on every layer which is not going to work for me as it will ruin many prints. Got several msgqueue full pop-ups. After the print there are no images in /opt/dsf/sd/DuetLapse3/. The plug-in said deactivated, though it was working when I started. I did capture manually and the camera works. Idea where to debug?

Lets have a look at your config file.
Also - to be clear, you are running 3.5.4 SBC on Bookworm? Buster?
Also - since there are no images being collected - there is something wrong - so please include a log file that was created with -verbose.

The images are not created in that directory. See the info tab for the directory location. You should also be able to see them in the files tab.

Its best to get basic operation working correctly before adding pauses and such.

@stuartofmt I will have to try again since I just switched to 3.6. I was on 3.5.4 bookworm. I started getting odd system delays after I bumped the swap file up to 4G. So I need to investigate that first.

@jltx I would start with the Duet pi image without making changes to swap etc.

As I indicated above - the 3.6 version is not yet available. It looks like there was a change or two to the plugin framework since 3.5 - so I have to track that down.
The 3.5 version will not install on a 3.6.0-beta.4 release. If you think it has installed - then something is wrong or you are not using the plugin installation method from DWC.

The documentation has several cautions about the use of the pause capability. It has the ability to set delays and can also interact poorly with the default pause capability.
I strongly recommend you get a basic config working first.

When you report back - with the config file and logfile info I requested above. That way we can see what is going on.

Hi - attached is a version of DuetLapse3 for 3.6.0-beta.4
If you want to try it be sure to remove the .txt extension

@stuartofmt Thank you for the update. I was able to install in 3.6 beta.

I am still seeing the same behavior. I removed the -verbose switch and still seeing message queue full. I am getting the long (~2 second) pauses at each layer which damages the print.

Here is how I am using: First I call M3291 B"DuetLapse3.start" in my start gcode. Then for each layer change I call M3291 B"DuetLapse3.snapshot". Finally in end gcode I call M3291 B"DuetLapse3.completed".

I don't think I understand how this plugin works. I'm not clear why I need to start anything. Isn't the snapshot command on each layer change sufficient to grab a frame? the final command I assume assembles all the frames into a video and cleans up. That's how I imagine it works (and what I want). But then other things don't make any sense to me. For example, there should be no need for anything like pause, resume, etc. because if you pause the print you will not advance any layers and thus the Timelapse, so that concept is automatic, no? I think my mental model is so different I can't figure out what I am supposed to do with all the available options.

@jltx

Your mental model is orthogonal to the intended use

Lets get something simple started and take it from there...

The usual approach is to start recording images at the start of the print. At the end of the print DuetLapse will create a video (you don't need to so so). You tell DuetLapse HOW you want images recorded with the options. These options are in the configuration file. At a broad level, images can be captured by layer, by time or even a combination.

What you were doing with your approach was asking DuetLapse the create a snapshot VIDEO on every layer change. It could not do that (not enough images) so it was spinning its wheels ...

I also suspect there may be other issues with your configuration (your reported delay between layers) but lets start off simply.

Why don't you try this config file - YOU DO NOT NEED TO PRINT . When you start the DuetLapse plugin you should see something like the screenshot below (after a few seconds). It will capture a new image every 10 seconds.

I'm assuming you are using a camera that streams via http. If that's not the case then tell my what you are doing.

-duet <your duet ip address>
-port <something other than 8080 e.g. 8084> 
-basedir /opt/dsf/sd/DuetLapse3
-camera1 stream
-weburl1 <your camera stream source e.g. http://192.168.10.140:8090/stream>
-seconds 10
-dontwait
-keepfiles
-restart
-verbose

Make sure you have a working installation. Something like this after about 15 seconds.

Wait until you have over 51 images (Status tab keeps count) - this will take about 8 minutes. You can wave your hand in front of the camera or something to while away the time
Then:
[1] From the DWC interface send M3291 B"DuetLapse3.completed"
[2] Wait 15 seconds or so - video creation can take 10s of minutes with a large number of images.
[3] In DuetLapse UI -- Go to the Files tab - you should see a video has been created. You can click on it.

If there are issues with the above then before I can help - I will need a copy of the log file and configuration file.
You can click on the logfile from the Files Tab and it will download via your browser.

When you have this verified - come back here and I can give you a couple of changes to config and let you loose on a print job.

ALSO _ PLEASE USE THIS VERSION OF THE PLUGIN. I have been making some minor changes and introduced a bug. I am not sure what I had done / not done with the version I posted a few days ago.
