Problem with pronterface and endstop


I have a problem with pronterface. I created a gcode using a estlcam and loaded into pronterface. It shows something like this in the console and there is no model showed.

The print goes:

from 0.00 mm to 0.00 mm in X and is 0.00 mm wide
from 0.00 mm to 0.00 mm in Y and is 0.00 mm deep
from 0.00 mm to 0.00 mm in Z and is 0.00 mm high
Estimated duration: 0 layers, 0:00:00

After I start, it shows endless echo:endstops hit: and moves a bit in x, y then z like trying to home. I cant solve a problem.
I dont have endstops, used firmware from this site

Did you try repetier or showing travel moves like I put on Thingiverse?

Did you try my test gcode to verify things are correct or only your own gcode?

Thanks, I will try it. Btw I recognized that in pronterface i can move manually only in one direction, for example x+, but not x-, like it be endstop triggered. It should be like that?

Not with my firmware.

Try repetier so you can use all my tutorials, it will make things much easier for you.
