Timelapses, are they possible?

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

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

resam

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?

yes it does

resam

do you have the timelapse python script running multiple times?
reboot the pi and make sure to not start it more than once.
it's probably easier for debugging to remove the autostart and enter the command into putty directly.

yes you're right it's running twice I'm afraid, once for the autostart and maybe the second when I log in?

resam

if you used /etc/profile or .bashrc, then yes - this will likely cause multiple starts.

ok, I leaved from profile ad rebooted pi

as before

Have you got an idea about the problem?

Good morning....I've tried to understand what could be the problem reading the script but Phyton is over my knowledge...could you help me? Thanks!

I've tried to use this as well: https://dr-b.io/post/Duet-3D-Printer-TimeLapse

But it doesn't work for me because of a parsing error with the JSON given by the Duet webserver I suppose...I can't contact the author of the procedure (my questions haven't been moderated yet)....does anyone use this? In case not does anyone know if in the latest version of the Duet webserver somehing has been changed in the JSON mentioned in the above link?

Thanks
