Cura 2.3.1 and to many retractions

[Thomllama 4]

Just started playing with Cura 2.3.1 .. noticed it's adding a MESSS of retraction that aren't seem to be needed.. any ideas?

Mac OSX - 10.12.1 - Cura 2.3.1.

just a simple example.. you can see in Octoprint.. the red dots are retractions.. there is a mess for no reason along the edge that should be just a simple outer circle...

Hi Thomllama, could you share a screenshot of what settings you have enabled for retraction? Does this happen all the time, or just with this specific model?

It can be that your mesh has a lot of vertices at some locations in your mesh.

As a quick fix, you could run it through an online repair tool and see if that changes anything.

Good luck!

I would, but I actually deleted Cura 2.3. gone back to 1x.x.x cuz it just works.. I do like 2. better for options being all in one list instead of 3 locations ( basic one, advanced 2 and expert in a 3rd location/window)  

but retraction setting were all stock.. near changed a thing..

It does do it to every model I slice in 2.3  -      it's a pretty simple model right out of Fusion 360.. which again.. older Cura has zero issues with.  nothing is broken in the file as the Mac's viewer shows it fine (Mac's will black out an STL with issue when you view it in Preview)

the one in front is Cura 15.x.x. the one in the back with the lines missing here and there are Cura 2.3

Netfabb no longer works as the got bought out or some such thing.. never figured it out anyway.

Is your Combing setting is enable ?

And try with Zig Zag infil.

This two options schould fix your issue.

Combing was enabled

Not sure what Zig Zag would do as it's when printing the border.. but worth a try.

so just reloaded Cura 2.3.1. seems the combing setting does help! not enough time to print before going off to work but the display in Octoprint seems to show better movements. Guess I didn't have it on before..

OK.. it's still using WAY to many retractions with 2.3.1.  combing doesn't seem to help here.  the bottom area in the image is just supports.. seems the older Cura understands this where 2.3 doesn't?  or something?

Oh about support there is a bug in the Cura 2 version.

I'de already open a topic about that. The team said that the bug will be fixed (partially) in the next release.
