i constructed a body for blenderCAM -> milling. However, the surface is not respected (the tool follows not the surface but drops down to final Z-height).
I think this is not cam specific, but some error in my geometry, which I can not find. Any ideas?
This is a body (bezierCurve.002 in the blend file) for which it works as expected:
You see the toolpath travelling on Z=0 (top) and then going down to the surface and following the surface.
For another body modeled using the same sequence of steps ‘c1FullCurveBeforeArray.001’ (explained below) the probelmatic behavior occurs:
Here you can see that the cutter drops down to final Z, not following the surface - as if it would not be there.
How are the bodies modeled:
- I make a bezierCurve (it actually is a cross section of a surfboard and I need to match certain locations exactly, therefore bezier and not nurbs).
- convert it to a mesh
- remove duplicate vertices
- make a face
- duplicate and shift it
- select both and bridge edge loops
- recalculate outside (I checked normals in both cases everything looks fine)
As a result I have the two bodies.
I can find no difference and it’s not clear to me why in one case everything works as expected, and in the second not.
Any ideas how to debug this?
