Cura 4.3 not scaling properly

Recommended Posts

Posted · Cura 4.3 not scaling properly

Hi

 

I have a model to scale, but not the same ratio between X / Z and Y.

X and Z should be scaled 99,6 % and Y 98,8 %.

 

So I have first rescale uniformly the model to 99,6 %.

Then unchecked the uniform scaling

Then changed the Y ratio to 98,8 but not clicking

Then after clicking, the result is

Looks like the X and Y are not properly taken into account.

 

I've redone the following test, starting from a full scale model, unchecking the uniform scaling

Then setting the X to 90 % and press enter. Both X and Y ratio are changed to 90%

 

There is a new bug in 4.3....

did you rotate the model, something goes wrong (bug) if the model is rotated and scaled.

Yes I did rotate the model 90° along the Z Axis in order to fit on the build plate.

 

I haven't noticed the bug before, as it's pretty rare to have to rescale not uniformly a model before printing

I find if I use file type .OBJ instead of .STL and make sure the 3D model was exported in MM, then it's all good. If I don't then it get's whacky.
