Bambu Studio Issue: One of the Merged Object Lifted After Slicing

I’m experiencing a problem in Bambu Studio where one of the two merged objects is lifted 2-3 layers above the print bed after slicing. I’m trying to print a two-color name card (with the front face of the card facing down on the Bamboo PEI Textured Plate.

Here’s my process:

  1. Design and export two separate STL files (logo/letters and rectangle shape as the card itself) from TinkerCad.
  2. Import both into Bambu Studio (tried both versions 01.08.02.56 and 01.09.01.66 and none of them worked as I was hoping too).
  3. Color each object using the paint tool.
  4. Ensure both objects are “Lay on Face,” then merge/assemble them (CTRL+A, right-click, merge/assemble, arrange all objects).
  5. Slicing the Plate raises the name and logo about 2-3 layers above the plate, showing only the card on the first layer.

I’ve tried splitting and re-assembling the objects, re-exporting the STL files, but the issue persists.

Could this be a software bug? Am I missing a step? Any assistance would be greatly appreciated. Thank you in advance for your responses and help.

Hi
the same issue for me.
It drove me crazy, because it started happening just after I have installed the new version of BambuStudio (mine is 1.9.1.67)
With the previous versions this merging process it was smooth and ok: now it seems not anymore possibile, because I tried to recreate the same project I successfully did before updating the Bambu version (a week ago or so), but now I am not anymore able to get the final slicing result

I hope someone could fix this

Thanks for sharing the experience and glad I’m not the only one that is experiencing this after the upgrade.

I’ll see if i can report this somehow to the Bambu Support Team.

I have opened a ticket, in GitHub, and I have used also part of your details (they ask for the steps, and you did a clear job).
Let’s see.
Anyway, I have found that if you manually move down your logo, in a very precise way, finally you get the result you need, even though at that point the main object is “floating” and Studio asks for supports (just a layer).
If you add them, after slicing you will see kind of supports appearing (not very useful for the print, I guess)
I haven’t print anything yet, because luckily I have done a lot of these jobs before updating

Thanks Paolo. I might have to give that a try and see what happens. It would be nice if it was back to the way it was before the update. Please keep us posted here. Much appreciate it.

Hi
finally I got the answer from the developers:

"When two parts have different colors and overlap, we give priority to displaying the color later in the object list.

You can drag the blue part behind the white part in the object list"

It works, actually. It means that if you have an object and a logo, when merging, assure that the logo is the last in the assembly list.

have a nice day

Thank you very much Paolo! Very much appreciate the follow-up. I’ll give that a try and reply to the thread in case it helps others not aware of this as well.
