Issue with Hinges Disappearing After Scaling in SuperSlicer 2.5.60

[NotTooOldDeveloper]

Hi everyone,

I'm facing a problem in SuperSlicer 2.5.60 and hoping someone here can help or share insights.

When I slice the original model, everything looks perfect, including the hinge. The hinge is represented correctly, with a hole and a rod, functioning as a moving part. However, when I change the scale of the model, the hinge seems to disappear. The area where the hinge should be gets fused, and it behaves like a single solid part instead of having the intended moving mechanism.

Interestingly, this issue doesn’t happen in Cura. When I scale the same model in Cura, everything scales nicely, and the hinge remains functional.

Has anyone encountered this issue before in SuperSlicer? Is there a workaround or specific setting to deal with this kind of problem?

I appreciate any advice or guidance!

Scale 100%

Scale 85%

This is intended behavior to fix issues in problematic models that have unintended small internal gaps. Print Settings > Slicing > Filtering > "Slice gap closing radius". Decrease this value by approximately half (I happen to use .049mm, though that's pushing it even on a very accurate printer) and the slicer will no longer consider that gap "false" and close it. Note that you are likely to have issues with this hinge due to the size of that gap -- wall fusing becomes difficult to avoid at a certain point.
