Application Version

5.3

Platform

windows 11

Printer

ender 3

Reproduction steps

while uncheking "drop down model" and rising it slightly from the bed, the following happens.

blue line is where the model should be printed, but preview clearly shows it being printed from the bed instead. happens with either tree and normal support types.

Actual results

cura is generating a preview (not tested in a actual printer) that is far from the user input.

Expected results

it should rise the model and place supports below.

I believe this is a change made with 5.3.0, but I'm not sure if it's a deliberate change. It certainly doesn't seem like it.

If you'll humour me, try disabling Generate Supports and then disable the Remove Empty First Layers setting under Mesh Fixes. Note that this setting is completely absent in the event supports are present (generated or user-specified), however it is still being applied despite its status. Restore the supports afterwards and try slicing again, and let me know if that's made it behave more in line with what you expect.

Apologies for the delay in response.

It worked like it should with your guidance. but those two options contradicting each other, and being very stashed away is something that still should be adressed.

That's pretty much what I expected.

I'll flag this for investigation. It's an undocumented change from 5.2 and feels like it shouldn't be happening, but ultimately it's the main dev team who has the final say.
