Cura 2.3.1 and to many retractions

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?   5a33242704612_ScreenShot2016-11-25at6_01_56PM.thumb.png.54f92a169c67bb9101033b3001935f9c.png5a3324272b6db_ScreenShot2016-11-25at6_02_13PM.thumb.png.c22d0c314c6e82dab66210092b679d14.png

    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.

      • UltiMaker Cura 5.3 stable released
        In this stable release, Cura 5.3 achieves yet another huge leap forward in 3D printing thanks to material interlocking! As well as introducing an expanded recommended print settings menu and lots of print quality improvements. Not to mention, a whole bunch of new printer profiles for non-UltiMaker printers!

      • Here it is. The new UltiMaker S7
        The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
         
         
        So what’s new?
        The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
         
        The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
         
        The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.
         

         
        The UltiMaker S7 also includes quality of life improvements:
        Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more  
        Curious to see the S7 in action?
        We’re hosting a free tech demo on February 7.
        It will be live and you can ask any questions to our CTO, Miguel Calvo.

      • UltiMaker Cura Alpha 🎄 Tree Support Spotlight 🎄
        Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
         
        We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
