Calibration or slicing Errors please help
I calibrated my steps/mm and using Thingiverse 20mm test cube thing 943755 (thanks to deBaer for this one). The result was a 20mm cube with actual dimensions X=20.05mm, Y=20.01mm & Z=20.14mm. My issue is that whilst the holes on Z-Z were spot on those through X-X were flattened top and bottom slightly and even more so on Y-Y. Printer is an Aetet A8, Repetier Host V2.1.3, using Cura slicer built in. Am I missing something in the calibration or some other setting in the slicer?
