When I open a model to print they always prompt me with a message that the model is too small, and is auto up-scaled 25.4 times. I save my .stl files in inches, and this conversion works perfectly well.
Until today. I opened a model (technically “larger” than any of my previous models) and it didn’t auto up-scale. The model was converted to mm, and was nearly microscopic. I manually up-scaled it the 25.4 times and everything is printing fine.
Why would some models auto up-scale and others wouldn’t? Also, is there a setting/feature where my models will just show up in inches, as my CAD files all are? I’m not really unhappy about this little quirk, now that I know how to handle it, but I just wanted to know if this is a settings issue, or just something I have to live with.
