Calibration problems with Rostock

Hello,
i built a Rostock Delta Printer over the last few weeks but now i have a few problems at calibration.

My first problem is the height at the Z tower.
When i calibrate the Rostock properly and then adjust the Home Position in x or y (not z) the calibration screws totally up.

My second problem is the alignment of the effector platform, when i move the head in one of the corners the whole platform tilts.

I have a RepRap Rostock with Traxxas Rods and i use Marlin Firmware.

Kind Regrads,
Marcus

you should only home with g28, and homez.

different software gui interface differently for homing. repetier host for example moves beyond zero then homes from e-stop for the axis, which is an issue for the delta bot. i think pronterface just issues a command of g28,
g28 x0 for example.
