.STL file becomes miniature size upon import (PrusaControl or Slic3r)

Been having great success designing models in Fusion360; slicing and encoding with PrusaControl, to make some very nice results. Lately I've experienced this problem, after inserting a model file (.stl) onto the bed (in the program). The file shows up in micro scale.. I mean TINY.
I found re-scaling by 2500% brings the model to the 100% dimensions it was supposed to be. Does anyone have a resolution to this/Are you having the same problem? Trying Slic3r returns same result.

Thanks!

You need to set Fusion 360 to use metric mm units when exporting to STL. Lars has a video on YouTube that shows how. The correction from inches to mm is X 25.4. More here.

Or you are making prints for ants.

That worked perfectly! Mades some sense of my math; your saying 25.4 times larger equated to my scaling by 2500%... 2540 then, would have been right on; but there's no need to scale now that I have your conversion reminder!!

many thanks.

Is there no way to have Slic3r import a model in inches so you don't have to scale each part by 2540%?

I’m pretty sure there are no units in STL files, so it wouldn’t have anything to clue it in that it should convert. Best they could do is add a “Murica” button that was essentially a hard coded “scale 2540%’

For me, I just started modeling in mm and haven’t really looked back.
