@alankilian @rjenkinsgb @Phaedrux :
the solution is ultra stupid 
it is my mismatch between radius and diameter... 
Orignal line:
M665 R717.765 L682 B500 H600 ; Set delta radius, diagonal rod length, printable radius and homed heigh
the length of the rod does not fit to the printer radius!
the correct config line is:
M665 R358.883 L682 B250 H600 ; Set delta radius, diagonal rod length, printable radius and homed heigh
Here is an error message quite helpful - from check perspective quiet easy to calculate.
Maybe this is possible to include while interpreting the config.g.
Many thanks to all for helping in this forum
