UM2 - Problem with Z-Axis

[jtschichold 0]

Hi,

I have received my UM2 couple of weeks ago and I have started doing some experiments to better understand this "3d printing" stuff.

Today I have printed a calibration object (https://www.youmagine.com/designs/5mm-calibration-steps) using default Cura (14.06.1) parameters. All the resulting cubes have perfect X- and Y- dimensions, but they are all 5.5mm tall.

What should I adjust to get rid of this distortion ?

Thanks and sorry for the lame question.

Very strange. Usually Z is most accurate direction. And usually PLA and ABS shrink. They don't grow!

I am happy I am experiencing something unusual :-)

I am using Colorfabb PLA/PHA filament at 200C with heated bed at 60C.
