Cura Slicer Adding Width to Wall

Recommended Posts

Posted (edited) · Cura Slicer Adding Width to Wall

I am using Cura 5.0 (but the results seem the same with 4.11.0).  The Cura slicer appears to be adding width to a wall once the wall reached layer 167.  At 166 and below, the layer is fine.


I have verified that the original model in FreeCad has a constant width of 2mm.  The STL file also seems correct.  


I have added another piece of information.  The new attached image shows that Cura is actually changing the inner wall width.  It seems to increase the inner wall width for walls that are not connected at both ends.


Any ideas why Cura would be adding width when sliced?  Thank you in advance.

    I have figured it out.  I had a setting of .1mm for Horizontal Hole Expansion and it was expanding the interior outer wall by .1mm.
