printing stops before completed

Printing keep stops just before complete.

I'm doing calibration and fine tuning for my first DIY printer.
Whenever I try printing some test files, print process stops like it finishes all job, but it isn't.
It stops just some steps before finishing final layer.
You can see the white circled area in the attached file.
And also unfinished FPS status bar in the screenshot.

I'm using Marlin and Repetier-host.
And test file generated by sketchup, is validated at 'netfab cloud service'.

I have no idea what's wrong with current settings.

Any help will be appreciated!
Thanks.
