Timelapses, are they possible?

see

It's exactly what I've read but I can't find a Wiki to understand how to use it...I'm not a Raspberry expert so for me the issue are:

Raspberry Pi / Single-Board Computer on the same network as your Duet
with Python 3 and the requests package
Webcam that returns snapshot pictures (still image) via an URL
mjpg-streamer or similiar: http://127.0.0.1:8080/?action=snapshot

I think that I had to "throw away" motion eye, right? Or is it possible to use it feature to have an URL fort he still images?

In case not should I install only Python 3 and mjpg-streamer to my Raspy?

Thanks
Andrea

p.s.
as you can see I'm not a Raspberry/Linux expert....sorry

if it can produce single images then no, otherwise yes.

It produces single images

But I can't undesrstand how the command M118 P4 S"LAYER CHANGE" ; take a picture could trigger the shooting of a pic....where do I have to put the URL given? In the web control? I am missing something...

the python script enables a telnet connection to the duet and listens for the "LAYER CHANGE" info
the webcam url is an option for the python script

Generating timelapse videos is quiet an opinionated topic in 3D-printing - everybody has a slightly different setup and preferred way of doing it. This is how I currently run my printer setup:

There are two things needed to make print-synced timelapses:

your slicer needs to insert the M118 commands on every layer change
your raspberry pi needs to run the timelapse.py script

You need to enable Telnet support in your Duet board with M586 P2 S1.
You can start the timelapse script on your RaspberryPi like this:
./timelapse.py some-folder-for-all-images/ 192.168.1.42 http://127.0.0.1:8080/?action=snapshot
(with the IP address of the Duet printer, and the URL is in my case mjpg-streamer returning a single jpg image)

ok, now the fog starts to raise a little....so, in order:

I can keep motion eye on my Raspy and install Python 3 and then copy timelapse.py on the Raspy SD
I have to insert the M118 in the layer change as you wrote on github:
M400 ; wait for all movement to complete
M118 P4 S"LAYER CHANGE" ; take a picture
G4 P500 ; wait a bit
does this work on IdeaMaker too (I think so)
Do I have to execute manually each time the launch of the script and the timelapse rendering? Isn't it possible to execute them automatically in some way?
Least and last I didn't understand where the final timelapse MP4 will be stored...

Thanks for your help

I'm not familiar with motioneye - if you find a URL that you can call and it returns a single still frame as jpg or png, then yes.
I'm not familiar with IdeaMaker - most slicers have some "on layer change" script section were you can enter a few g-code commands
with a bit of Linux knowledge it should be easy to do - with varying levels of complexity. I would recommend searching the web for "crontab" or "systemd" in this context
All the still frames and the final rendered movie will be in the folder path you passed to the timelapse script as first argument

ok, thanks! I'll do some searching and testing!

Hi, I've installed everything but it doesn't work (of course I've missed something).

If can help when the I connect with putty I get this error message:

this is what I've inserted in etc/profile:
sudo python /home/pi/timelapse.py timelapses/ 192.168.1.7 http://192.1.168.13:8080/?action=snapshot

resam

try with sudo python3 ....

python is the old version - python3 is the new one (which you need).

resam

go and run: python -V and then python3 -V

You will probably see that the first one returns 2.7.something and the other one 3.something.else.
We need 3.something for the timelapse script to work.

You can also avoid this monkey dance by simply calling the timelapse script itself:
sudo /home/pi/timelapse.py timelapses/ 192.168.1.7 http://192.1.168.13:8080/?action=snapshot

uh ok....I'm not a Linux expert....I've change from python to python3 and now no error appear logging into....I've started a trial print to see if all works...I'll let you know in few minutes!

it's printing but I don't see images going into the folder as long as layers changes

just start the script in the interactive console (putty) directly. It should print a few log lines so we can see what is happening.

Did you enable Telnet in your printer config?

yes

resam

ok - that looks right. However it is failing to send commands to the printer...
Does the error message repeat after 15-20 seconds?
