You can use this simple and quick to print Thing to check that your X axis is moving perfectly square (perpendicular) to the Y axis. This can be useful especially on home built printers. After printing, measure the distance from each diagonal corner of the square. If the measurements are equal then your printer is square if there is a difference then the printer's axises are not square to each other.
