yes Mark, with the 115.200 it runs really fine but now i have a other issue.
It looks that the endposition switch for the z axes is defect, because actually i could not print because the first layer will not stay on bett.

"the first layer will not stay on bett."
you mean it will not stick to the bed, right? If so, try to adjust the distance between the nozzle and bed, if it's too high the filament will not stick to the bed well.
