Getting started problem: Print not starting



i have a self builded LCD UV-LED printer, a raspi with the actual image and a ramps 1.4 board. After setting up the printer, i have made some tests, z-axis is working properly and the UV Led is switched on by shutter G-Code. I can see the calibration image after opening the shutter. The display is connected by HDMI. After Slicing a model, the z-axis moves up some millimeters and that’s it. The elapsed time is not starting. I have attached the log, perhaps someone could help me to make the machine work.

thanks in advance!
