Better Understanding NanoDLP Log

In an effort to better understand what is happening in NanoDLP, so I can maybe tune my printer better I have started looking at the log files.

My first question is are the log entries perhaps generated asynchronously and thus possibly the times are log times vs when an event actually happened?

It seems like things like shutter opening and image
display are out of order (I would assume the image would be displayed then the shutter opens then the shutter closes after
the cure time then the image is cleared) but from the log it doesn't appear that way....maybe shutter speed and delays cause some
out of sync issue?  It clearly works as is but I am trying to understand what I am seeing in the logs.

Below is a log snippet.... from shutter open to shutter open so it should be a full layer.

I'd love to know what the "Unknown command: ' '" is but it doesn't seem to hurt anything.
I print with an exposure time of 12 seconds I am trying to find where that exact time is in the log....
I assumed it was between shutter open and shutter close but that seems wrong, maybe it is between
display image and clear image but that too is not 12 seconds...close but not really at computer speeds.
The one second delay between the logging of the delay and the Shutter Open, seems about right on..

TIA

Re: Better Understanding NanoDLP Log

The most of actions and loggings are async. So no guarantee log orders are correct.  Unknown command being passed from RAMPS so something could not recognized by RAMPS.
Curetime looks a bit more than what actually should be as it count time which gpu acknowledge displaying layer but logging happens as soon as nanodlp try displaying a layer.
So actual cure time is less that what recorded here.
