Cura ignoring certain settings when slicing?

Recommended Posts



I've come back to 3D printing after a break of a few years and I've started using Cura 3.4.1. I'm having a problem whereby it seems the slicer is ignoring certain settings I choose. The ones I noticed were secifically: Top/Bottom Line Direction and Bottom Layers. Regardless what I set them to, Cura seems to just use the defaults. Check out the attached pictures. Am I misunderstanding some feature of the interface?


Thanks for any help.

Yeah - it's every model. I've just upgraded to 3.4.1 and on my previous version - 2.7 - it also worked fine. I've noticed other settings don't work either: Infill Density, Infill Pattern, Wall Thickness, Wall Line Count. The list of settings that work is shorter than those that don't. Changing profiles doesn't help. Even when I switch to recommended settings, I can't change infill density, only layer height and build plate adhesion. I re-installed Cura and it hasn't helped.

    • "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.
