Cura 3.4.1 adding large bottom plane


Recommended Posts

Posted · Cura 3.4.1 adding large bottom plane

Beginning yesterday, when I import a file into Cura 3.4.1, a large plane is being shown underneath the drawing, causing the drawing to be too large for the printer. I tried raising the piece up from the bottom surface of Sketchup (17.2.2555) but it didn't help.  I removed a line in the drawing so that the bottom surface was erased, and then redrew it.  That worked & allowed a normal import into Cura. However, I made a modification to the drawing today, & I'm unable to prevent that bottom plane from appearing. I attached pics of the drawing in Skype (showing it raised above the bottom surface of Skype), and then showing it in Cura. When the drawing is on the bottom Skype surface, the bottom plane is connected to the drawing in Cura. Any ideas? Thanks.

    Hmmm. I just thought to look for an online STL file viewer, and that showed the bottom plane as well. It seems my Skype STL export extension is the problem. When I started Skype yesterday it told me there were extension updates, and that must have broken it. Thanks anyway. ?

    For anyone else having the same problem, I solved it in Sketchup by having the piece selected (which it should be anyway when making the group), checking the "Export only current selection" box in the STL export dialog. I never did that before, and never had any problem until yesterday -- but that took care of the problem.

    Your problem is using Sketchup, which is ill-suited for 3D printing.





    In general that is true, but I have found that Sketchup is good for editing some STL files that have problems or are otherwise unprintable.  You need to know what you are doing, however, and use plugins that check for watertightness.  Also Meshmixer is good for fixing more complex STL files.  That extraneous plane could have been easily removed using Meshmixer.

      • 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!
          • Thanks

      • 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.
