Cura 15.06.03 "Horizontal Expansion" bug?

Something interesting I noticed today while making a print.

I was printing a camera bracket, which I had previously printed except for a slight change to the length of the rail and clip, and because of the small size of the holes I decided to try -0.1mm of horizontal expansion. I noticed a few minutes in that the printer was not printing one solid piece, but rather it broke the model apart at the start of the clip. (image 1)

Here is an imgur album depicting the bug:

It appears that horizontal expansion thought that the model was two pieces put right next to each other, and that it needed to add a 0.1 mm gap on both peices resulting in a 0.2mm gap where the peice should have been solid.

(images 4&5)

I'm curious if anyone else has experienced this, or if this is an intended feature.

If anyone would like, I can post my .scad file or the .stl for this model.

Thank you,

-Ntwede

    Are you talking about the far right upstanding piece?

    My first thought was that these pieces were not merged in CAD and therefor Cura identifies these as 2 parts. You could try to merge them, or use one of the 'fix horribles' in Cura (under expert mode).

    Hope that helps (or I am interpreting your question right ;))

    Hi, thank you for your input.

    Yes, the far right piece is the separate one. It shouldn't be a problem with the way I designed the model, as the two pieces overlap and I used

    union()

    {

       piece 1

       piece 2

    }

    to make the entire model.

    Obviously I can just change the size of the holes in my model, and I don't actually have to use horizontal expansion to fix the sizing issues, but it was an interesting bug I thought I would share.
