Retraction

Noob question.

Printing with MakerGeeks Maker Series PLA. Duplicated the pre canned Cura PLA profiles. Printer is a new UM3. Things look great but getting extra material oozing when making larger moves. I have tried a wide range of temperatures and it doesn't seem to make a difference. So assuming I need to move to retraction settings next. It appears that there is no retraction values set under the material profiles in Cura.

Question is if this is the next logical step to combat the oozing, and any recommendation on some starting values to input on the material profile for a UM3?

    Good luck. I came here searching for the same answer. I'm honestly not too impressed with Makergeeks Maker Series PLA. The Black HD Glass filament was a giant pain in the butt and was string city. I am testing a Makergeeks silver at  6.5mm at 45mm/s retraction, and it still hasn't improved much.

    Whilst you temp. is not making a difference for you, you must try and print as cool as possible. Reduce you temp until you get under extrusion then back off 5 degrees.

     

    My retraction settings (for PLA) are 

    Distance 5.5mm

    Speed 50 mm/s

    Minimum travel 1.0mm

    Maximum count 90

    Min. extrusion distance 0.2mm

     

    This is not to say they will be the best for you, you should do some tuning but maybe they give you a start.

     

    Important to realise that filament impacts this; i.e. your settings which work well for one filament may need some tuning for another filament (even sometimes the same filament type e.g. PLA from the same manufacturer) - not usual but can happen). In my limited experience I would say that different filament types, e.g. PLA vs Nylon may well need tuning.

    Different colors from the same manufacturer most definitely often require different settings. I've found the more clear/glass filaments tend to require more retraction.

      • 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 5.3.0-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.
