How to remove retraction that happens at walls?


Recommended Posts

Posted · How to remove retraction that happens at walls?

I have a 3 extended printer. So far I've tried to disable any retraction that is possible in Cura's settings, and it turns out that all the major retraction disappears. The only part I don't understand is retraction still happens at walls:

 

1. Filament is retracted a few mm back when printing an inner wall

2. After the inner wall is finished, filament is pushed forward a little before it prints the outer wall

3. After the outer wall is finished, filament is pushed forward a little again before it starts to print the infills

 

 

Note that my model has several loops of walls on the same layer, not sure if that has anything to do with the retraction. See image attached.

 

I'd rather have the filament not retracted at all despite the side effects that might cause. Any idea how I can disable it?

    Do you have combing enabled?  Combing enabled will do fewer retractions.  Combing disabled will do more.

     

    When you go to PREVIEW mode set the mode so it shows moves in blue.  Dark blue is non-retracting moves.  Light blue is retraction moves.  Are you seeing light blue moves?

    i think i find the answer, by enabling coasting that tiny bit of retraction is gone

    I was thinking of coasting but coasting doesn't retract so I didn't mention it.  It should have the dark blue line (no retraction).  It also doesn't extrude.  So instead I mentioned about the colors to see if it's really retracting (I think it wasn't retracting).

    something weird about the Preview mode is that for some reason it only shows the model in translucent grey, but not the paths of printing... it used to not be like this. paths of printing only appears if i click the "play" button at the bottom

    If you are in compatibility mode (the preview shows flat lines instead of 3D sausage shaped lines) then one of the visibility settings is "Top Layer Only".  That will leave a lot of the model gray as the slices just isn't being shown.

    found out what the issue is... the layer was not turned on lol

     

    thank you both for commenting!

      • 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.
