Printing hollow object with no bottom layer

[MAPedersen 0]

I have a hollow stl file that i want printed with no bottom printed layer desired. Using Cura 4.8 & have 0% infil as well as "Spiralize Outer Contour" selected.

Tried to print and the bottom layer was printed. Again the stl file did not show a bottom to the part. Is there a setting i should be looking for?

NEVER PRINT something without checking the PREIVEW mode first and sliding the slider to see what will happen on all the layers.  Never.  That would have saved you a lot of time and will help you realize within seconds what each option in Cura does.

 

So I recommend you don't use "spiralize" as that has a built in "water tight" feature for vases and cups and I don't think you can disable that.

 

Then make sure "bottom thickness" and "bottom layers" is set to zero and you will get no bottom.  Also disable infill as it sounds like you want your part to be hollow (no infill).

I am trying to get the exact same outcome as the original poster (no bottom layers/0% infill/Bridged top layers). I have the latest version of Cura 4.12.0.

I am using the settings described by gr5 above.  No spriralize and bottom layers/thickness set to 0.  However Cura still adds the bottom layers! what gives??

Load the model in Cura an set up to slice.  Use the "File | Save Project" command to create a 3mf file with the model, settings, and printer and then post that 3mf file here.  It's the easiest way to remotely troubleshoot.
