Variables and placeholders for layer time
is there a variable for layer time?
Id like to do something along the lines of (IF layer_time > 60 seconds, move to location) ELSE move to another location
to explain what im trying to do further, every layer change i have my prusa move to a location, to press a button on a remote for a camera, to take a picture.. problem is, if that layer time is longer than 60 seconds, i need to press the button twice, first time to wake the camera back up, and second time to actually take the picture. its a cheap gopro knock off, with no control over when it goes to sleep.
this is all for doing timelapses

This is all I know of ... maybe someone else has deeper knowledge of specific Prusa placeholders.
RE: Variables and placeholders for layer time
There are other ways to get timelapse photos without having the physically press a button. Take a look at Octoprint and the various plugins that monitor the gcode stream.
Meanwhile, if you really want to move the head around on a fixed interval, you could insert some custom gcode on layer changes. The only problem is that the printer doesn't remember where it was before a move, and there's no easy variable (that I'm aware of) you can reference to return to your starting position. Some firmware seems to support a feature to store positions, but I don't know if Prusa supports this.
I'd also worry about nozzle ooze, bumping the print and other problems. I believe you can insert commands to set unused GPIO pins that could be wired to your camera, but again I haven't researched this thoroughly.
