Over Extruding with an AnyCubic Mega S and Cura 4.4

Recommended Posts

Posted · Over Extruding with an AnyCubic Mega S and Cura 4.4

Hello forum.

I am new to 3D printing and have had reasonable success with printing small miniatures (something with not much surface area).


However, I have been trying to print something with a bit more width and I have an issue (that was also present with my earlier prints, but did not cause so much of an issue as they has a small surface area).


The issue is that I seem to be extruding when the print-head is moving to its next position. I have spent a lot of time ensuring that the print bed is level and clean. I have adjusted the 'Retraction' flow, Hot-end temperature, Bed temperature within the Cura configurations but to no avail.


The printer is an AnyCubic Mega S with the supplied 1.75mm filament.


Any help or pointers will be gratefully received...

Harold Clements

    Hi and welcome!


    You can try if it is better when you turn off combing (search for the setting in Cura)

    For me it seems it is a normal travel move inside the object and therefore no retract happens, because it doesn't matter. With combing off, the printer should retract also when traveling inside the object. 


    I am not sure if there are more settings with an effect on the retract, I normally don't care about it.


    To avoid just the line on your first picture you can set combing to not in skin, that you don't have such lines on the top surface for example.

    set combing to be "everywhere but skin".  something like that.


    Also in layer view, turn on movements (check the box).  You can see which moves are retraction versus non-retracting (different shades of blue).


    You want to make sure these moves are retracting moves (by default they are non-retracting and leave that line you don't like).

    Thank you very much... This has fixed my issue.


    I am very grateful for your help and so will my grandson whose xmas present I am trying to print. I know I am cutting it fine to be ready for the day, but the printer was an early present for me 🙂


    Kind Regards,

      • 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.
