3D PRINTER TIMELAPSE GUIDE
Same layer.
Same frame.
A smooth layer-by-layer 3D print timelapse is mostly about repeatability.
THE IDEA
Move the printer, not the camera.
A normal interval timelapse takes pictures while the nozzle and bed are in random positions. For a cleaner layer-by-layer effect, the printer should move to a known photo position before every shot. The camera stays fixed, the model grows in the same place and the toolhead is kept out of the frame.
For bedslingers, the bed position matters as much as the nozzle. Pick a repeatable X/Y park point that is physically reachable and keeps the nozzle clear of the printed part, clips and frame.
SAFE PARK MOVE
Lift, park, settle, shoot, return.
A small Z-hop can reduce the chance of the nozzle touching the part while travelling to the photo position. After the park move, wait for motion to finish and add a short settling delay before triggering the camera. Even a fraction of a second can reduce vibration and motion blur.
Always test the chosen coordinates manually before adding them to a real print. The printer's usable travel can be smaller than the nominal bed size, and accessories can reduce clearance. Preview generated G-code in the slicer when possible.
CAMERA TRIGGER
Keep the trigger consistent too.
K-Snap uses an ESP32-C3 to coordinate the printer's park event with a phone or supported camera trigger. The important part is that the camera receives one trigger after the printer has stopped moving, not during the travel move.
Once the sequence is finished, keep the images in filename order and stitch them at a fixed frame rate. K-Snap Timelapse Studio can turn the captured sequence into an MP4 directly in the browser.
