    I too am in need of a trunion Based XYZAC configuration. Any chance Rab or someone else is working on that? Dan mauch

      Are you talking about where both A and C axes rotate the workpiece? I know there s an xyzac where the A rotates the workpiece. You may have to go into the

        Are you talking about where both A and C axes rotate the workpiece? I know there's an xyzac where the A rotates the workpiece. You may have to go into the code, save-as another file version & change it so the C rotates the toolpath like the A. But have you run all of the versions to check, because there may be one already. Just run it in Gmax, create a simple toolpath (5 axis) & run the animation to see if it rotates the workpiece.

          Yes A and C axes rotate the workpiece. When you ask have you run all of the versions are you referring to the menu choices for machine configurations? For my test I made a hemisphere and projected some concentric circles down onto it, I chose the xyzac configuration and generated the gcoge for it. If the xyzac configuration was configured for a table table style setup what I would expect to see happen is the hemisphere tip to the side on the A axis and then the C axis cut the circular path, the Y and Z axis would have to move to compensate for A axis movements, but there should be no reason for the X axis to move. What I saw was both X and Y axis moving. If the cnctoolkit script needs to be edited to make it work for a table table style setup I think I may need some help understanding where in the script I need to hake changes.

            If you fast forward to about 2 minutes you can ship the part about my controls.
            My machine operates like Bill's post describes the motion and the need for a trunion script.

              Here is a better trunnion video of my 5 axis setup. http://www.youtube.com/watch?v=wD0zMushHRc

              The narrative was directed to a friend that wrote the code but he did not use the cnc_tool_kit. The problem with the tool kit is that the plugin was written for a heaqd mounted 4/5th axis and wouldn't work with a trunnion type system as in the video. Here is hoping someone would be willing to modify the plugin for use with a trunnion.

                  It would be easier for the original programmer as HE understands what it is that is required to make it work.
