This 20mm cube is a more challenging test to verify the deviation from the nominal dimension of the cad model and the printed part, that is 20mm between all parallel faces and the diagonal distance between chamfers is 28,87mm.
Great to see if there there is layer inconsistencies like in the prusa i3 MK3 and MK3S (602 issue)
IT has Diagonal paths
More changes in directions, could show some ghosting effect
A way to measure the distance between the combination of axis on the chamfered faces
Simulation of the print process layers
