Calibration Cube Z-Height

Hello All,

After some searching online and on this forum i can't seem to find a topic related to this issue. Here it goes:

When i print a Calibration Cube https://www.thingiverse.com/thing:1278865 the Z height doesn't seem accurate compared to the X and Y.

Printed in PLA, 0.2 layerheigt, 20% infill, 45mm/s. Extruder 210C, Bed 60C

X Meassure's 20mm dead on
Y messures's 20mm dead on.
Z measurres 20.2mm

1. Did Z Calibration
2. I started with checking Live Z adjust on my first layer, i ran the "Z Adjust my way" and got it nice smooth surface. Seems good.
3. I checked forum's and found out i need to calibrate Extruder; Measure software distance G1 E100 F100 vs filament distance. Got it dead on again
after some adjustments.
4. Lastly i printed the extrusion multipier Calibration Cube (40x40x40) to measure the average wall thickness, it was a little off. However i measured the
Z height of the Cube and it was 40mm dead on, X 40mm, and Y 40mm..

the Miltiplier Calibration cube however is a Prusa generated Gcode file. The XYZ Calibration Cube's i sliced myself with Slic3r. I got a feeling it has to do with the Slicing or the fact the XYZ-Calibration cube has a thicker layerthickness then 1 and thus has something to do with the Z-Height.

How can i get my calibration Cube Z height to 20mm? The Extrusion multipier cube is however only 1 layer thick. does this have something to do with the accuracy?

Thanks in advance.

.1 or so really isn't anything to write home about with fdm printers, but there are plenty things that could affect your dimensions.
