how can someone do a timelapse like that
it’s impossible to trigger the cam at that location
I’m guessing here, but, long before BL even existed, people would add custom gcode to each layer that simply moved the print head and bed to a fixed location so that the Timelapse looked this smooth.
They would normally also need to move the head to a fixed position so its movement would press a Bluetooth shutter switch though.
I suspect this one is benefiting from something like Octoprint that can observe the printer as it’s processing the actual job and it is the one either moving the head and bed and then triggering the shutter or it watching out for the custom gcode to be triggered and hits the shutter itself.
Again, all guesses.
very cheap with low cost off-the-shelf electronics, ir laser and photocell - trigger each frame on rising edge, say,
