Raw beginner so treat me gently if being stupid!
I have a couple of downloaded freeware .stl files that have invisible items in Blender. I cannot make these visible, they just do not seem to exist, but they appear when in Repetier-Host Object Placement.
If slicing the file (with CuraEngine) for printing is attempted it runs OK until the process reaches printing the layer height where these item(s) are and slicing/print then stops, way incomplete.
The phantom item is a small circular disc with a triangle emerging to one side. Have run file repair to no effect, the file reports as manifold, and normals OK.
All I need to do to use this file for what I want is to rescale (which I have done OK), and print, yet it will not print all of it!
I thought I’d Import the .stl file into Blender and delete, but Blender does not display them!
Is it me?? :eyebrowlift2:
