I chose the 'External Camera - Script' Camera Type, and provided the path to the trigger script ( /home/pi/scripts/trigger-snapshot.sh), as well as the path to the initialization script ( /home/pi/scripts/initialize-camera-save-to-sd.sh) in the 'Before Print Start Script' option. Configuring OctolapseĪt this point, I created a new camera profile for my D700 following the Configure Octolapse instructions. The camera will store photos on its card as if you hit the shutter button yourself. Make both scripts executable: chmod +x initialize-camera-save-to-sd.sh trigger-snapshot.shĪnd then test both scripts and make sure they work. # trigger the camera and exit immediately # Requires a camera initialization script with the following command: gphoto2 -capture-image -set-config capturetarget=1

# Camera Capture Script - Leave on Camera, Don't download Gphoto2 -auto-detect -set-config capturetarget=1 Run 'gphoto2 -auto-detect -get-config capturetarget' to determine the appropriate setting # IMPORTANT: The capturetarget setting may vary.
# Set camera to save images to flash memory # Put the arguments sent by Octolapse into variables for easy use # File: ~/scripts/initialize-camera-save-to-sd.sh I created two scripts for my D700 following the guide, both inside ~/scripts: #!/bin/sh due to oozing filament while the camera captures an image), and for overall workflow for most cameras is to not transfer the captured image back to the computer, and to do that properly, you should follow the guide for Configuring a DSLR With No Download. But the best option for print speed, to prevent print errors (e.g. Second to that is the guide I linked earlier. The easiest (and the recommended way to do it the first time, so you can make sure things work like you'd expect!) is to plug in a USB webcam, and use it. There are a few different ways you can capture and process time-lapse sequences with Octoprint.

It's a lot faster to transfer and process JPEGs for a time-lapse, though for normal photography I'm shooting RAW all the time! Automating the Shutter Release Make sure to configure the camera to store JPEGs unless you need to be able to do more post-processing on them as RAW files. You can also snap a picture and have it downloaded to the Pi: $ gphoto2 -capture-image-and-download Then I rebooted my Pi, and made sure the Pi saw the camera: :~ $ gphoto2 -auto-detectĪnd then I told GPhoto 2 to snap a picture: $ gphoto2 -capture-imageĪfter this completes, it will store an image file named something like capt0000.nef on the camera's memory card (in my case, an SD card in an SD to CF adapter). Pi ALL = (root) NOPASSWD: /usr/bin/gphoto2

Then, because gphoto2 needs sudo privileges to run (since it's working through USB), and it's annoying to deal with the sudo password that's required by default if you install the OctoPi image on your Pi, I followed the instructions to add the following line to the end of my sudoers file using sudo visudo: # allow 'sudo gphoto2' to run without supplying a password

What's Octolapse? It's a plugin for the free and open source OctoPrint 3D printer web interface, and it allows extremely customizable control over time-lapse creation for 3D prints.Īfter plugging the D700 into the Pi and turning it on, I logged into the Pi, which is always running headless on my network, using SSH, then I installed GPhoto 2 using: sudo apt-get install gphoto2 I followed FormerLurker's excellent (and official!) guide, Configuring an External Camera with Octolapse, but I'll review the important parts here. So how did I get it working with my old but trusty Nikon D700? Read on. What I wanted was a stable and sharp timelapse of the entire process with high enough resolution to use in HD videos I produce for my YouTube channel.

I had already tried using my pi-timelapse script with a Pi Zero W and the Camera Module v1 and v2, but the quality is just so-so, plus it's not synchronized with the 3D printer, therefore at least on the Ender 3 V2, the printed object goes all over the place: After seeing GreatScott's video on creating great 3D Printing timelapses, I knew I had to make better 3D Print timelapses using one of my DSLRs.
