Contour seems to ignore some geometry... #312

when i do roughing and contour (X axis with 1/8 bit at 0.4 stepover) on provided model, resulting g-code seems to leave unfinished geometry with just roughed finish:

Just realized it can be mitigated by lowering/changing the stepover... It's probably not even a bug. Weird thing is that roughing has same stepover, but manages to get there...

can you provide a .kmz workspace usings files --> export? contouring slices the part in a completely different way than roughing.

yeah. i think it's more like feature than bug... contour just moves in pre-defined lines given by the stepover, while roughing works with offsets of the mesh geometry, that's where the difference comes from...
