Cura & Ultimaker Orig. prints 25% smaller! in Cura + plugins Posted June 20, 2015 Hi Everyone, I have a really strange problem with STL that I generated from my Solidworks package. When I import the STL into Cura, I have to rotate the model 90 deg. to have it positioned in a printable fashion. Looking at the model using the "Scale" settings panel, all of the dimentions look right. However, upon printing the model, the actual physical dimensions are about 25% smaller than the STL itself. (eg: If I have a 20mm tube bring printed, it actually prints at 15mm.) Can anyone make a suggestion as to why this might be happening? I am building a tube that is using a 1mm shell, 30% infill, with the latest version of Cura and firmware. (Cur 15.04, with the latest firmware uploaded.) Thanks in advance! bob.
