Test print for CoreXY printers

thingiverse

A diagnostic pattern designed to assist in pinpointing printing imperfections on a CoreXY Two Trees Sapphire-S printer. I had begun to suspect that the source of my subpar prints might be related to their placement on the bed, as well as the direction in which the walls were printed - counterclockwise for outer walls and clockwise for inner ones. Printing this pattern helped me determine that it was actually more about the orientation of the walls rather than their position. In my case, walls oriented along the X and Y axes produced poor results, while those with a diagonal orientation fared significantly better.
