5-axis TCP / RTCP setting

Hello,

I am looking for a method, a calculation to set my TCP / RTCP exactly and precisely. Can anyone help me .

Thanks for your help

Renishaw Axiset software works well for this. But there is no LinuxCNC support. They probe a sphere around the b rotation and measure error of calculated point to actual point. Than they use the same setup to track the sphere through the arc. This should give you the true centers compared to calculated centers. It is fast and accurate.
