liyu running flexi 8.6 not cutting to contour line

[plugy 0]

I have updated for flexi 8.1 to 8.6 because my liyu cutter inst cutting to the contour line,

But it is still the same, i have calibrated my plotter so the cutter sits over the optical eye mark.

The optical eye follows the contour line instead of the cutter so is of the distance between the the cutter and optical eye.

How do i rectify this pulling hair out

try putting the cutter over the mark and see what happens

From what I have read you are better off lining up with the knife point.... Skeeter just posted a good link about how all that works... They even have a name for it and I forgot already....
