nanoDLP

I now changed controlling of the shutter from Ramps to GPIO of RPi.
With Ramps-Board I had lot vibrations.
But NanoDLP ignores the "Servo Signal Length".
The Projector begins to exposure at the same time when the shutter begins to open.
The shutter need about 500ms for complete opening.
In "Projector Calibration"->"Shutter Open" / "Shutter Close" I can recognize this "Servo Signal Length", but not during printing.
