after Homing my Axes it shows an error "KinematicsInverse failed".
I think my D-H Parameters are wrong or?
I don't know if incorrect DH parameters can cause the calculation to fail. I can imagine that it might if the DG params are set up such that the effector position is not in a position that a robot described by your parameters could reach.
Unfortunately there are at least two definitions of the DH params, and I am not sure you you tell which one any particular description is describing.
I have observed that some descriptions use "a" for the arm length and some use "d" and I think that that might correlate to which version is being used.
The Wikiepdia page describes both formats. Genserkins uses "Modified DH parameters"
