Bambu Studio 2.7.1.62 Coplanar Object Problem

I created a Flat card 1mm thick with a cut out to hang from a rear view mirror. When I select “Lay On Face” it shows multiple planes for the bottom face which I created as coplanar. The problem is this object has multiple parts, the card which is coplanar and texts parts which are flush within the bottom surface. Since Bambu Studio doesnt see this as coplanar some of the text parts disappear. I really miss the prusa splicer version that would cut anything below the print plane. Does anybody have a good solution? I tried to use cut but that doesn’t seem to work reliably either.

When you imported into Studio, did you do it as multiple pieces to a single thing where they all move together in Studio?

If you did, then the issue may be with how the parts were exported from whatever design program you used. I know in Fusion if you move parts from their desired positions and then save the parts, they come into Studio similarly displaced.

If the card actually has protrusions in its design, you may be able to move the asssembly where the parts you don’t want are below the build plate. Below the plate they just don’t print which might leave you with the flat surface you want.

I fixed my print. I had a couple of issues:

  1. Even though it was flat art and depth was only added in blender, it was not treated as truly co-planer. I wound up modeling the card from scratch in blender and that fixed the coplaner issue.
  2. My final model consisted of 14 parts imported in as a single model into BambuStudio. Bambu had some difficulty dealing with all these parts resulting in unpredictable print results. I was able in blender to join these into a five part model I was able to successfully export from blender and import into BambuStudio,

I am not 100% convinced that BambuStudio had an issue with the 14 part object, but simplifying the model into less parts did cut down on overhead and shortened the import time.
