Posted · Blender not scaling properly

I am trying to print a wheel from blender with my ARTILLERY GENIUS printer.   On Blender, the wheel is 50mm in diameter and 20 mm thick.   After loading into Cura it displays a message "your object is too small and got scaled up to minimum print size."   The rescaled object is 12.5mm in diameter and 5mm thick, ie it has been scaled down by 25%!   what has ahppened?

    I'm sorry I don't know blender but are there options for the units you are drawing in?  If you are drawing and export the file as inches then it will come into Cura and be autoscaled.  Cura is guessing.  So you need to double check the units in Blender and the Blender export utility (if it has options).

    Once the model is in Cura, select it and use the Scale tool and adjust the Z to 20mm.  With the "Uniform Scaling" box checked you should get the X and Y for free. and they should be really close to 50mm.  After you do that check the % boxes and they may give a clue as to what scale Blender exported the model.

    A lot of Cad modeling apps don't care about units.  They only know that two lines are "1.00000000" apart.  It could be lightyears or nanometers for all the Cad app cares.
