I have a problem with cutting with an engraver that starts at 0.50mm and goes up to 3.14mm but it seems like the program doesn't calculate its angle
in fact, with a flute that has a diameter of 3.14 throughout its length, the cut comes out correctly.
Can anyone tell me why? is a known bug?

Here is the result with the 2 tools:

FreeCAD does not yet respect different tool tips. You can, however, use the engraving operation or turn the compensation off, if you want the path to be spot on the edge.

Maybe I didn't understand correctly, are you telling me that all this stuff here is completely useless?:

Currently yes, perhaps opencamlib based 3D surface respects toolshapes different from a flat endmill.

Is opencamlib supported by my version of freecad with python? I have already tried this thing in the past and I had to abandon it due to various problems between the python compiler or something I don't remember.
Thanks for your help.

FreeCad 0.19 is a solution or https://www.freecadweb.org/wiki/OpenCamLib

I think in 0.18.4 it should be in the bundle by default?
