Moment of Camera capture.

By default, camera capture takes place during exposure.
How could I instruct nanoDLP to take a shot after the lift?

Use after layer gcode or syscall input to send command to take photo manually.

[[Exec raspistill -o public/shots/[[LayerNumber]].jpg]]
I added this command in the GCODE After Each Layer box but it caused some weird behavior:
It caused the projector to expose almost half the build area at full brightness for a split second.
When I removed the command the problem went away.

If my description is not helping I can produce a short video.

It is probably caused by raspistill, but it is strange as after each layer runs after image displayed not before that.

I see.
Is there another way I can grab a shot when the platform is at the lift position and display it on the dashboard?

Use Exec with bash script and call raspistill from there.
As I remember raspistill had quite long delays before taking photo so it is possible it takes photo during layer cure. It has some switches to decrease delay, maybe it fixes the issue.
