Hi im new here having a bit of trouble with Cura 4.4 its a little hard t o explain
but when i go to preview a sliced model all that is in view is support and the model  its self
 does not load in as sliced. does anyone know how to solve the issue

there is an image attached of the issue i have a couple of model 
that have done this to me and would like to know to sort them out

    It's probably a non-manifold model. Could you run it though an online checker (or download the mesh tools plugin from the marketplace)

    any pointers as to what checker i should use sounds really stupid i know

    What software are you using for cad?  If it's sketchup or blender I can help you with fixing the model.


    You can look at the model in cura in xray mode - if you see any red then that's the issue - you can zoom in and pan around until you understand it better.


    You can fix any model with the netfab free service online.  You have to create an account but it's free.


    I'm not sure where there are mesh tools to check your model.  Try googling around a bit.  Meshmixer is free and has some features for fixing non-manifold models but I haven't tried that feature yet.


    It could be that your model is fine (manifold) and you simply have model walls thinner than 0.8mm.  This is common with architectural models where there are lots of very thin walls.  If that's the problem then it's easily fixed with certain cura settings.  You could test for this by setting line width to 0.1mm just briefly to see if that fixes your issue.

      • 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.
