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
Andrea

have you tried Danal's version?

no, not yet

That handles both versions of responses from RRF

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)

Hi, I've seen that you have updated the scripts and I've installed them....following the instruction nothing works, tho enly way to make it take snapshot is, on putty, to insert manually the command:
python3 /usr/local/bin/duet_timelapse.py /home/pi/timelapse_tmp 192.168.1.7 "http://192.168.1.13:8081?action=snapshot"
but in this way it captures the snapshot but doesn't produce the final rendering...without python3 it doesn't work at all, so I've changed duet_timelapse.service in this way:

[Unit]
Description=Duet Printer Timelapse
Wants=network-online.target
After=network-online.target
StartLimitIntervalSec=0

[Service]
ExecStart=python3 /usr/local/bin/duet_timelapse.py /home/pi/timelapse_tmp 192.168.1.7 "http://192.168.1.13:8081?action=snapshot"
User=pi
Group=pi
Restart=always
RestartSec=1s
Environment=PYTHONUNBUFFERED=1

[Install]
WantedBy=multi-user.target

but it doesn't work, I've tried to insert python3 /usr/local/bin/duet_timelapse.py /home/pi/timelapse_tmp 192.168.1.7 even in crontab but it doesn't work....what am I missing?

You should not need the python3 ... prefix.
What does systemctl status duet_timelapse.service say?

@resam said in Timelapses, are they possible?:

systemctl status duet_timelapse.service

it looks ok

[resam]

Nope - "auto-restart" means it crashed somewhere...

What does journalctl -t duet_timelapse.service say?

journalctl -t duet_timelapse.service

Whats your current ExecStart line? I think you might have messed around with it a bit too much
