Time-controlled time-lapse recordings in 3D printing are popular, but technically not trivial. Anyone who has ever seen how an object is created layer by layer, seemingly without the nozzle moving, will appreciate the effect. Such recordings usually require special software solutions such as OctoPrint, including a suitable plugin – a setup that many hobby users find too complex.
With “LayerLapse”, Whopper Printing now offers a simple and cost-effective alternative in hardware form. The compact module uses a Hall-effect sensor that triggers a camera signal as soon as a magnet on the extruder moves over it. All the user has to do is attach a small magnet to the printing nozzle and insert a defined parking position at the end of each layer in the G-code. The sensor then triggers the release process at this point – a clean, repeatable method for layer-accurate images.
The LayerLapse board also offers a freely assignable GPIO pin. This allows other cameras to be synchronized or external systems to be controlled, for example. The specific benefits are currently limited, but open up scope for creative applications.
LayerLapse is currently available as a finished product. According to the developers, a kit version is in preparation. Alternatively, the required components can also be put together yourself with a little experience. The firmware is freely available under the MIT license.
LayerLapse is an interesting option for makers with DSLRs or mirrorless cameras who are looking for an uncomplicated solution for creating high-quality time-lapse recordings.
