Cura's adding material that shouldn't exist


Recommended Posts

Posted · Cura's adding material that shouldn't exist

Hello, new here and have finally had it with this print. At layer 6 and 8 are where the problems are. Layer 8 generates 2 triangles a square and a rectangle out of the blue. I've tried re editing the file and this and that but it still adds those shapes. 

 

Second issue is with infill. I can't get any infill to show up in the hinges or in the lid with the latch piece. Last time I made something similar, infill worked and random shapes didn't pop up. Any help would be appreciated ty!

 

Using sketchup and cura 5.0

 

File and pic attatched.

    Matter of fact, I cannot get any infill to show up on any of my models now. That spiralize setting is off btw.

     

    Update.

     

    Got infill back when I went back to cura 4.13.0 although I'm still getting those shapes.

    This is from MS 3D Builder and it is the "U" shaped hole in the middle wall.  You can see that something isn't right.  SketchUp is notorious for things like this.  You need to take a close look at your model to make sure the surfaces aren't flipped inside-out, and other errors.

    After repairing the file at an on-line service I get this...it's still wrong, but at least it's different.

    This needs to be fixed in SketchUp.

    The good news is that the Infill is there.  Are you sure you have "Infill" turned on in the linetype settings?  You can see it in the above image (but I use the sidebar GUI so my screen might be different).

    You are 100% right on this one. It was a problem in sketchup. Between the bottom layer and the bottom layer of the "compartments" was set to a gap of 1.5mm. I increased the gap to 1.55mm, exported again and bam it works, no more weird shapes. Also tried going shorter to 1mm and it worked normally again. I can't understand for the life of me why it's upset with 1.5 but hey.

     

    As for my problem with no infill. I've narrowed that down to version 5.0 of cura. Like I said I went back to version 4.13.0 and then infill works.

     

    What version of cura do you use? Also thank you for your help, I appreciate it!

     

    I added the fixed version if anyone wants.

    I moved to 5.0.  I wasn't much of a fan of the Arachne beta's but the full implementation of the variable line width in 5.0 is much better.  The dialog boxes and controls are funky though.  If it's because of simple unfamiliarity of the developers with QT6 then that problem will go away.  It may be that QT6 just isn't complete enough (or something) to allow controls as most people are used to.

     

    If you open one of those "no infill" gcode files in a text editor like Notepad and search for TYPE:FILL does it find the sections of the infill code or is it missing from the gcode file as well.

     

    This is your new model is MS 3D Builder.  That "U" shaped hole still has issues.  There are extra "infinitely thin" surfaces that intrude across the hole.  Because the triangles that make up those error surfaces extend to the floor I still get the extra material on the floor as well.

    The 3mf file below has a model that I cleaned up (Me_box) in MS 3D Builder, and your model.  Look at the differences in the Prepare screen both in regular view and in X-Ray view and then slice and inspect the preview.

      • 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.
