Distortion Calibration (Delta)

Hi guys!
I had a problem with my delta printer. I'm trying to calibrate the distortion that takes place on the z axes. Below an explanatory image when printing a cube. There is a tool or a command in Repetier-host/firmware that corrects this issues?

    This distortion should not be possible at all. z moves run on all stepps the same number of steps so all distortions in xy plane stay the same over z height. 

    The only way to print in that direction is having the rotation matrix tilt print direction, but then the bottom/top would also have the same rotation, so it would still be a cube.

    One thing I could imagine is that one motor belt has a different resolution maybe just due to different tenson. Then you might get something like that, bit with tension the error normally is very small so I hope your example is exaggerated.

    Thank you for your support. Maybe it's about the mechanical. I'll check it out.
