dc42, Thanks for your help. Z max feed rate of 3 mm/sec, solved the problem.
I found a Marlin verion especially for Prusa i3, and there also the default steps were 8.000/unit. and there the speed was reduced to only 1 mm/sec.
George, I think you are completely right, but I do not know where to adjust the driver settings.
Really nice how things are solved here, within 12 hours!!! Thanks again.
