Hi,
I did the cube test to see what is the printing accuracy in X, Y, Z axis. According to the Ultimaker 2 specs, they should be 12,5 micron for X, Y axis and 5 micron for Z axis.
I printed a 10 mm cube in regular PLA at the highest quality possible in Cura. I then measure with a high precision digital caliper the distance between two faces of the cube (measured in the middle of the faces) in all three axis.
I got the measurements : 9.94, 10.02, 9.94
So that is a 60 micron difference with the baseline, or 5x worse than the published specs.
I knew manufacturers were often lying on their published performance specs but I did not imagine it was 5x !
Has anyone tried this test and compared it to specs ?
