Hi, please help me to solve this problem.

I have:
-Raspberry Pi 3
-A4988
-Led
-Nema 17
-5 inch screen
-endstop

Wired them all according schematic from this site.
1. When i test Projector calibration, screen and shutter works. The test images appear on the screen, shutter (LED) also works
2. Step motor is also working
3. End stop is also working
4. When i send STL file to print:
   4.1. First layer appears on the screen. LED goes on.
   4.2. Then on the secon layer "RAMPS Sync - Waiting for done message from RAMPS" and it is waiting command from RAMPS.
But there is no RAMPS, i am doing direct control.
What is the problem here ?
Thanks.
Here is the log
