This one is a bit unusual, but I’ve recently seen a few time lapses made by 3D printers with some kind of camera control software integrated into them, such that the print head seems not to move, and the part just kind of rises up. Very cool.
They are obviously just taking the pictures when the print head returns to its start point.
It got me wondering if such a thing might be possible with a CNC.
Two not very good possibilities occur to me. One is that you add retractions after every path, and then somehow setup a camera to take a photo at the top of each retraction. Perhaps with just a mechanical trigger or something.
The other idea would be to do some fancy image processing to remove the spindle, probably by cropping and merging photos together. I could create an action in photoshop to do it, but I still expect many hours of tedium, fixing all the ones it misses.
Both of these methods seem daunting and inefficient in their own ways.
Anyone have a clever idea to achieve this? I don’t suppose GRBL can control a camera…
