Floating/Hovering Object when brought into cure

[the5jfam 0]

Hi everyone, very new to 3 d printing. I have only printed pre-made objects on the SD Card that came with my Ultimaker 2 Extended+. The problem I am having is that after slicing my object to fit on the print bed in meshmixer, I export to Cura and the bottom half of what I sliced lays flat on the printer bed. However the top half is floating. When I put the file on the SD card, my Ultimaker immediately starts printing about 10mm above the print bed just like it shows me in Cura. So how do I get the top half of the file to lay on the printing bed?

Please somebody help me solve the mystery of the floating 3D Object so i can start printing things.

The quick answer is: go to advanced tab, then quality section and in "cut off object bottom" enter 10mm.

The better answer is to figure out what went wrong in meshmixer such that it left something 10mm below your part and delete that.

Also keep in mind you should always look at your part in slice view also before printing it as this shows up lots of potential problems - make sure you scroll through EVERY layer at least briefly - you can use shift+up arrow and down arrow to go through layers quickly.

Also look at your object in X-Ray View Mode in Cura for any Red areas. Those would be problems with your object that Cura can't resolve: holes in the mesh, stray lines, non-solid areas, etc.

Couldn't you just lower the model [-(a few)mm]?
