Just found a paper that talks about making a post processor: "A postprocessor for table-tilting type five-axis machine tool based on generalized kinematics with variable feedrate implementation"
www.researchgate.net/publication/2573371...drate_implementation
It talks about redundancy resolution for selection of B and C axis angles and also talks about re-sampling the tool location data points from the CLData for a higher resolution output using spherical interpolation for the tool orientation vectors.

As promised the document to the XYZAB-TDR kinematics:

Can we add that document somehow to the documentation?

As far as I'm concerned sure.
But from what I understand about the build process for documentation an asciidoc format would be preferred to a PDF as that is automatically built in the LinuxCNC build process. While I can export the jupyter notebook in asciidoc format all the math is spit out as 'latexmath' which in turn does not show in the auto built documentation (I think). So looking at other mathematical documentation (like Rudys trt-kinematic docs) the math formulas seem to be cut out of the pdf as images and then pasted into the asciidoc document and that is a lot of work for which I have not had time or motivation. If there is a less time consuming way to add it to the documentation please advise.

This is the raw export as asciidoc:

Note how the math from the python output is not included as latexmath at all so that would have to be reentered manually which is real pain.

Hello, i try the source you describe sa-cnc.com but none of these are available
Maybe something is changed.

Is new information available

Thank you in advance

Sir, I think that site has not been working for more than a year. If you need old pages or PDFs, those URLs may help you.
