Hello,
when i generate a cnc file with fusion360 and the linuxcnc turning post processor, the result is also not matching my work piece, It looks like its taking the diameter instead of the radios somehow, in all case when i touch off my work piece in this way(perhaps here the problem is situated):
going to the start of the work piece outer right side and  outside corner and set x and z to zero, when i start now the file, its always starting around the  radius towards me in the air in stead of the work pieces surface.

Generally you would set X to the diameter and Z to zero at that corner.

The (0,0) point for the tool tip should match the origin of the setup, the red-green-blue XYZ triad:

do you mean to the diameter of the work piece or the resulting diameter of the finished part?
