Incorrect slicing

Recommended Posts

I downloaded a bracelet from Thingiverse, sliced it with Cura and printed it. Strange things happen in the print, the head prints in parts where it should not.

I Cura, the bracelet looks good.

I inspected the code with Repetier host, and indeed, the things which print wrong are apparently in the gcode. Repetier Host shows exactly what the UM is printing.

See pictures.

How can I avoid this?

(Cura also has a GCode preview, so you could have seen it there)

Cura shows those little red lines after slicing, those are actual errors that the slicer sees in the model, could be holes or duplicate faces. Most likely one of those is causing the erroneous infill.

You could try running the model trough netfabb cloud, or slicing at a slightly different layer thickness (which could be why the original creator of the model never ran into this problem)

    • "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.
