Bug with Cura using 0.16 layer height with a floating object causes 0 print time.

Posted · Bug with Cura using 0.16 layer height with a floating object causes 0 print time.

I'm using version 4.7.0 of Cura with a Creality Ender 3 profile, and when I try and slice a model that's not touching the bed plate, with layer height set to 0.16, Cura acts like it sliced a model, but there's no model, and the print time is zero. It only happens when the model is floating and at the 0.16 layer height.

    I used a 25mm cube.  Yes, with the object floating it doesn't slice (it didn't matter what layer height I used).  With a support block under the model, and the support block set to "Print as support", and with the model just touching the support block, it did slice.

    With the 25mm cube rotated in space so that only 1 point was touching the plate it did slice.  With the same configuration, but the model floating above the plate and touching the support cube it also sliced.  Just floating there it would not slice.

    An oddity was that with a 5mm thick support block located at Z = 0, the model cube I was using also needed to be located at Z = 0 even though it was 5mm above the build plate.

     

    For a minute there I was thinking that the Cura team had successfully debunked Sir Isaac Newton, but they must have had to back off because in Cura 4.8 beta the issue doesn't happen.  A pity really.  I'm sure that proving "gravity is a myth" would have meant Nobel Prizes all around.

      • 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.
