Nothing Appears But Grey Shadow

[SEKN 0]

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.

I am having this same issue.  A student made a spherical object and when I load the stl, it is just a grey circle shadow on the buildplate.  The scale does not seem to matter.  Help!

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.

Here is the link to the document.

 

I'll try what you suggest - Thanks!

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.
