Cura 14.03 combing fail?

Recommended Posts

Hi,

I wanted to print this model (link) at 0.5 scale with combing enabled. Looking at the layer preview there are travle moves which do not respect the layer boundaries.

Isn't combing supposed to travel only inside the model? The "inappropriate" travel moves correspond with ugly bumps on the printed model (even when printed at 20mm/s and 200°).

Actually, these results are expected. The areas where no combing happens are so thin that combing would have a bad effect on the outside skin quality, as the nozzle would be traveling too close to it. So it retracts and travels. (You can see the retraction marks on the preview)

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
