The kinematics may not be wrong. It depends on what the gcode is telling the machine to do.
Just saying the kinematics is wrong doesn't lead anyone to be able to understand where your problem is. A simple post processor will generate gcode that needs the kinematics in the machine to run a part. A complex post processor will generate gcode that will run the machine with simple kinematics. My guess is the kinematics is not in the post processor and the kinematics is not in the machine control software. If you have the machine axes tuned then a proper gcode program will move the machine to cut the part you want. You do not need to use anything more than trivkins to run your 5 axis machine if the kinematics is incorporated in the gcode program by the post processor. If you want to be able to program complex parts my hand then you will need complex kinematics in the machine control. My cinci 5 axis machine runs the post processed gcode with trivkins. The machine has some geometry errors I corrected with a kinematics. I had a choice of putting the geometry compensation values in the post processor or in the machine control kinematics. I chose to put the compensation in the machine control kinematics. Hope this helps you decide where you apply the machine kinematics - in the post processor or the control software.
