XYZ Calibration Cube with Chamfers and Rounded Edges
Description
XYZ Calibration Cube with Chamfers and Rounded Edges ----------------------------------------------------------------------------- Additional features with respect to the original version: - Chamfers on top and bottom (45°) to prevent elephant footing to influence the result - Rounded edges to avoid acceleration/jerk settings to influence the result After printing, measure the dimensions in X, Y and Z direction. Then adjust the steps/mm settings according to the following formula: e = Expected dimension (20 mm or 40 mm) o = Observed dimension (measured with caliper) s = Current number of steps per mm (send M503 to printer) (e/o) * s = New number of steps/mm Note: -------- Adjusting the steps in X, Y and Z direction should only be done after making sure other parameters are set correctly which could also influence the dimension of the cube: - Bed Leveling - Material and bed temperature - Flow or Extrusion Multiplier - E steps - Line Width The step values for X, Y and Z are given by the geometry and motor and should usually not differ much from the settings by the manufacturer. Two versions (20 mm and 40 mm) are provided. The bigger one allows for a more accurate (smaller relative error) measurement.
