Cura 2.3 How to reduce useless retraction with support

Recommended Posts

Hello,

I've got an issue with Cura 2.3 (I havn't this trouble with 1.15, and I have the same useless retractin with Simplify 3D that's why I stopped to used it to Cura 2).

When I print a part with support (dual extrusion) I have a lot of useless retraction on the support.

I tried different support Zig Zag, Grid, etc... but I have the same useless retraction. I tried with combing Off, All, No Skin... Same results. I tried to increse the minimum travel to 2mm... Nothing change.

The modele I tried to print : http://www.thingiverse.com/thing:39751

And bellow the gcode result in Simplify 3D (each dot is a retraction) :

No it will be fixed in cura 2.4... and then still not fully, because to fully reduce retractions to a minimum would require write a bit more slicing time.

Inheritance issues are about how settings relate to each other. The bug resulted in some PVA settings being applied to the print you did with PLA if u would have them both selected, but printed with PLA only - I think..

I'll take some extra slicing time over failed prints any day. And even if excessive retractions don't lead to failure, they still take time during printing, a lot more time than extra slicing time (unless you're talking about going back to Skeinforge slicing times that is).
