BBL P1S

How to reproduce

• Download the 3mf from this model: https://makerworld.com/en/models/732468?from=search#profileId-664135 or open attached (see below)
• Open the 3mf both in Orca as BS
• Compare support settings, note they are basically the same

Actual results

• Orca adds 5.78gr of support

• BS adds 1.64gr of support

Expected results

I expected that just opening a 3mf in either Orca or BS would result in a more or less similar amount of support to be added, not a 3x difference

Using BambuStudio v1.9.7.52

Basically the same support settings can still effect it specifically the support threshold angle. My apologies if they are the same.

[pimlie]

Thanks, all support settings including threshold angle are the same in both UI's indeed.

Make sure the tree styles are the same between the two. Note: the default style of Orca and Bambu are different.

[pimlie]

Hmm thanks. Sorry for asking but which settings should be similar? The help popup for support style in OrcaSlicer points to https://github.com/SoftFever/OrcaSlicer/wiki/#support-styles but that doesnt show any info about support styles.

It seems that only Tree Slim/Hybrid/Strong are somewhat similar, although the calculated filament used for Support differs by a factor of up to 2 still between Orca & BS.
