Visual Delta3 controller

Dear, I really like your application. I also implement the same code whose reference you have given. I have a problem in cross checking the forward and inverse kinematics of the Delta Robots. I implement the given code in the MATLAB to find the forward and Inverse Kinematics. When I did the cross check then I get the wrong results. First I put the dummy angle in the forward kinematics and get the position, after that I put that position in the Inverse Kinematics but at that time I get the different angles as I put in the forward kinematics before. In your files, the code is not gicen. Can you send me the code of forward and inverse Kinematics ? Canyou explain this deviation in the cross check ? ? Thanks in Advance Zeeshan
