Slicing holes, seem to be about a nozzle width small

[Livermore-Dad 0]

I started a discussion in another location regarding some weirdness that I was having when attempting to create a 6.4mm hole and the hole was coming out to be 5.3/5.4 instead of the requested 6.4mm.. I enlarged the hole to be 7.4mm and it gave me roughly 6.4mm

 

It seems that others have found this also to be the case "as one member cited "it seems that a hole is always nozzle width smaller than requested".

 

This sounds like some slicing math or other, or that it starts in the middle vs the tangent..

 

Just be interested in hearing what the Cura programmers think about this and is there something that can be adjusted to get the holes to be requested size, when one is running larger nozzles.

 

Now note, the rest of the object was to spec, it was only the hole and obviously the top bottom (the sides of the hole, grew as the hole was made smaller than the stl required.

 

Would be very interested in if there is some computational changes or other to remedy this?
