Cura missing large support area

Posted · Cura missing large support area

Another strange problem:

I successfully printed a large oblong tray, about 180 x 70mm and 19mm tall.

Using Win-7-64, Cura 15.02-RC2 and the Ulti-controller. For appearance the convex side was printed up so it needs a lot of support. Zero problems with Cura.

On the same tray I added four small mounting studs and a 3mm hole.

The CAD model looks perfect.

The view in Cura looks perfect.

But----

When slicing it in Cura a very large 60x60x60 triangular area inside the upside-down tray is missing the support. One node of the triangle is near the 3mm hole.

I have spent way too many hours trying too many things without success.

 

  • I tried Cura 14.09 on another computer.
  • I tried a repair in an old NetFab.
  • I exported the SolidEdge file as STEP and then imported it back to SolidEdge and then again converted to STL. I was hoping that the conversion process would throw out some artifact that might be causing the problem.
  • I exported the SolidEdge file as IGES and then imported it back to SolidEdge and then again converted to STL. The IGES importing has options for healing STL files and I enabled all of them.
  • I turned it the concave side up.
  • I rotated it 45 degrees on the UM table
  • Many more tries and variations of the above.
  • I removed the hole in the CAD file. The support structure changed but is still way wrong.

 

The 3D rendering looks perfect. It is just the support structure that is wrong. It is hard to fix the CAD file if it is that is wrong when it visually looks perfect.

It is difficult to explain and visualize the error so I linked some pictures.

Here is the SolidEdge original file, STL, STEP, IGES

Hopefully someone can figure out what is wrong and how to avoid it in the future.

I am out of ideas how to fix it. I can always use the old version without the hole and mounting studs and glue in studs and drill the hole but that is not learning what is wrong.

Please take a look and let me know your suggestions.

      • 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.
