Bug caused by printing holes? - (missing layers)

(hopefully the images uploaded)

So I was printing a part which has a horizontally positioned hole in it and discovered that layers would be missing right about where the hole starts (refer to pic).

As a result, I did some tests by printing cubes with a hole going right through the centre (and one solid cube). Strangely, only the cube with the horizontally positioned hole would fail. The other two cubed were fine (solid and one with a vertical hole) - indicating that the printer is performing fine.

Is this an issue that can be fixed? If so please can you help me?

First of all you need to learn about layer view in cura. This would have shown you the problem before you started printing. When viewing your model in cura there are 3 modes - find layer view.

Nextly the problem is in your cad model. If you switch to xray view you can usually see the problem - if you see anything in red then that is the problem.

Most likely you have overlapping volumes of extra walls somewhere in your cad model. Was this sketchup? Sketchup isn't the best for making real things but I used it for a year so it can be done. Here is a guide to making manifold parts with sketchup:

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
