Calibration Estep Objects

Calibration cubes are useless due to proportion of printable dimensions your machine has. A 20mm cube on an Ender 3 is 1/10th of the bed and therefore can easily create errors of at least 1/10 in a full bed print. ie a 20mm cube with 0.01mm inaccuracy is actually over 0.1mm inaccurate over the entire bed of an Ender 3.

So all calibration objects for Esteps should take up as much bed as possible but remember the object must fit your calipers too. As calibration of XY and Z should be done separately due to the order of recalibration I have separate objects to save on filament.

Remember when doing Z Esteps you must calibrate initial layer height with a object gcode that you have modified to have only one layer.

Do remember to calibrate the extruder you must use vase mode or spiralise contour mode dependent on slicer.

P.S. The orientation is wrong because each way i try ends up wrong so I've given up
