Calibration Cubes

thingiverse

Made these to get a better tune than the 20mm calibration cube. Use the short and wide one for the X & Y calibration and the tall one for Z calibration. The larger sizes should help you achieve better accuracy, I got to less than .01 mm difference on my printer (around +/- .005mm difference). The larger size will help you measure a larger difference between expected and actual dimensions. This will make the calculation <code style="color:blue">newStepsmm = (expectedSize*currentStepsmm)/measuredSize</code> more meaningful as the difference between expected and measured size is more pronounced, and printing larger objects will (hopefully) be more accurate. DO NOT measure near the bottom of the print if it has elephant's foot, will throw off your calibration.
