Nothing Appears But Grey Shadow

Hi All. Does anyone have any insight as to why some of my files open as only a grey shadow in Cura?. The software seems to know the model parameters, because it will slice it, but nothing appears in any view aside from the shadow at the base layer, and nothing prints. Just confused as this happens maybe 5% of the time. I've attempted to go back trough several different software packages to adjust, but thus far no solution. Any thoughts? Please and thank you. Cheers!

    There are many reasons this can happen. The model can be too big. The model can have walls that are too thin (thinner than nozzle). The model can have holes in the walls (so cura doesn't know inside from outside of any point in the model).

    A picture of your model would really help.

    it seems to go grey when a model is rotated 180deg.

    Mine cleared in 2 ways:

    1. by reselecting "no skin" as the combing mode

    2. by rotating it back its original position again

     

    It did this each time I reloaded the model.

     

    It also lost the additional combing settings I had enabled so I had to reselect them in the settings menu.

    There have been enough of these now that I'm starting to think "Glitch".  This is the second sphere that has caused it.  The model is there as witnessed by the shadow but it's way above the build plate.  At any rate maybe this will work...

     

    Right click on the build plate.

    Choose "Select all Models"

    Click on the "Move" button on top of the toolbar on the left (below the file open button).

    The "Z" should be zero.  If it isn't then make it zero and hit tab or enter.  The model should show up on the build plate.

     

    If you could post the STL files that are causing this then the Cura Team could take a look.

    That was the problem - reset the z to 0 and it's there!

     

    Thanks

    I'm sorry.  I meant the STL file that you are actually slicing in Cura.

    (When I open your link I get a CAD site and it is read only.)

    I had the same problem but fixed mine a different way in case someone else might need this info.  I started out like GregValiant recommended and right-click on the model name and select all models.  But then I right-clicked again and chose Center Selected Models and mine appeared right where it was supposed to be.  Hope this helps someone.

    I had the same issue, seeing a shadow instead of the STL. The solutions above did not work for me. I ran the inspector tool in meshmixer but it found no problems. I then used the Make Solid tool under Edit in meshmixer. In the object browser, you'll see the original STL and the new object that has solid added to it.

     

    I made the original STL invisible and exported the new solid STL and, Al-hamdulillah, it worked perfectly fine.

    Just wanted to say thank you so much. Can't believe i didn't check this but you were 100% correct it was somehow using 1900.xxxx.

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
         
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
         
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
