Ender 3 V2 Separates the Print's Walls

Posted (edited) · Ender 3 V2 Separates the Print's Walls

I don't really know how to describe it, but I'm experiencing an issue where on opposing ends of the print, the walls are being printed further away from each other than normal. I'm a bit new to printing, so please help!

In the inner circle, you can see at the top right and bottom left, the walls separate. The blob is caused by me stopping the print. I'm using an Ender 3 V2 and Cura 5.2.2.

    @Schmordan that's still a mechanical issue.  Are you sure the X trolley doesn't wiggle and that the hot end is tight?

     

    This project file is with my printer active.  If you open it in Cura be sure to select "Create New" rather than "update".  (You don't want to over-write your own printer.)

    My settings aren't a lot different than yours other than being somewhat slower.  Your speed settings don't matter much on small models like this because the "minimum layer time" comes into play.

    I don't know how to describe it, but before a print starts, the printer extrudes some filament on the right side of the printer and then starts printing. I assume that it's to get the filament going through the nozzle, but when I printed with your settings, it dragged some filament over to the print as well, as you can see in the image above.

     

    I'm really confused. 🫤

    You might get better support reaching out to the Creality Ender users communities.

    But from what I can see from the picture...
    Your nozzle offset from the bed is wrong (its too close)
    You might be having hardware issues with your XY&Z axis as well.


    Your nozzle is so close to the bed when printing the brim its barely printed, but this is also causing build up pressure in your hotend.. when it moves to print the model it appears to be starting too high in the air, while also over extruding its built up pressure.

    You walls not touching (and being obround) points to motion issues in the XY..

    None of the above can be addressed by settings in Cura...

    Alright, thanks for all the help thus far! I'll try to find a Creality forum and see if they can help me solve the issue. Thanks for replying though. 🙂

    I think I've found the issue! For some reason, I've only been checking the y axis belt left and right, but I lifted it up and there was a lot of slack. I'll try printing and update you if it works.

    Yep.  Mechanical issue.

    BTW You've fallen behind so you'll be expected to work OT tonight.

      • 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.
