"enable combing" lost in Cura 15.2 (causing extreme retractions)

Recommended Posts

When I load a profile made with earlier versions into Cura 15.2, with "enable combing" checked, it is translated to "combing OFF", which causes zillions of retractions....

Took a little bit of cursing to find the problem. Please change it so that when in old profile "enable combing" is checked this translates to "combing ALL", that solves it.

These retractions happen mainly in the extra "zigzag" that is added to the inside of sloping walls. It would be nice if this "zigzag" was optional, as it is not always necessary and can ruin prints in transparent PLA because it is added for walls which have more slope but not for walls that are (almost) vertical. With "spiralized" printing this zigzag is never there, which causes much nicer transparent prints, but of course many objects can not be printed spiralized so I would like to be able to switch off those zigzags in some cases.

On the up side: some great new options in 15.2, thanks !

    • "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.
