How to prevent combing for first layer and top surfaces only?

Recommended Posts

Hi all,

I've been trying to find the right setting for this since forever.

I'm using the latest cura (2.1.3), and I am looking for a way to use retraction on the first layer and for top surfaces, and use combing for everything in between.

The main reason is to prevent the strings as seen in the attached picture on the first layer, and scratches on top surfaces where the print head combs over the surface.

Any help would be much appreciated!

Thanks

Björn

Hi there,

Turning off combing resolves the issue, at the cost of more time and more retractions. Cura 15 has a Combing: No Skin option that I think also solves the issue. I also heard there is a plugin that will do z hop on combing on the top surface, or something like that.

Cura 2.1.3 does not have the Combing: No Skin option, but the new 2.3 beta does get it back. But it is still beta.

Anyway, that is what I have read and what I have experienced. I too have been wondering about this forever and only recently started finding answers. :)

Anyway, good luck! Hope this helps.

Disabling combing is not a real option I think. Since retractions always leave marks on your print, I always want to avoid them.

I installed Cura 2.3, and indeed I get good results, although I do not understand all of its behavior.

Retraction = yes

Z-hop = 1mm

Avoid printed parts

Combing = no skin

This gives me the result I want, but it disables combing for more than just the first layer. I think it disables combing on all the solid bottom layers maybe, while just disabling combing on the first layer should be enough.

Anyhow, thanks for your help :)

    • "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.
