Scaling issue in Cura?

[twofoot 0]

Hello all.

I did a quick test by importing a known-working STL file of 6" diameter. When it was placed in the display of Cura, it came in at less than 1", and needed to be scaled by approx. 10x to reach the proper size. The drawing scale was inches, and I had not seen this issue in other program before.

Thoughts? Will I have to create a generic 1x1x1 cube to set my machine's "scaling default"?

Thanks

Chris

Check your export settings in the program that created the STL. cura is metric so that's the first thing to check, and I know some programs work in 10:1, 100:1 scale etc as well.

STL files have stateless dimensions. They are not mm, cm, inches, feet, or furlongs but could be anything.

Cura assumes mm.

If you had to scale 10x then I'd guess your model is in cm.

You probably want to scale by 25.4 exactly. Cura expects everything in mm.

Now that makes sense. I will set the STL up in mm prior to importing into Cura. Mercifully, it is a simple case of maths to get the correct dimensions to the machine.

Thank you!

Cheers,
