I wanted to use the Mint Null Points inscribed lines to align the styli in my other arms after I had set up the correct Spindle to Pivot distances and Overhang adjustments using the other templates and I asked Yip if the null points were in the same positions and he did not know!!??...a bit worrying?
Is it possible that he said that simply because he didn't know which geometry these other tools uses? Löfgren A and B for example have null points in different places.
