Lithophane With Other Slicers(?)

My default slicer is Prusa since that is the machine that I am using. When I load the generated .3mf into Prusa it appears as a bunch of different pieces which I can’t figure out how to merge. I can delete all but the pane but that leaves me without a frame or support.

Is there a strategy for using other slicers? Should I just use Bambu and export the gcode?

Try opening with orcaslicer - it has profiles for prusa machines and is able to read 3mf files generated for BS.

I will probably try that too. For now I deleted the frame piece (which would be a different color/print anyway), did a select all, Merge. I am going to print that and see how it goes. I forgot that Prusa has a merge function.
