RepRap Calibration Matrix

thingiverse

A sizable calibration matrix (measuring 145mm x 145mm) is utilized for pinpointing issues related to backlash and other intricate print quality concerns. This tool offers valuable insights into how your print output fluctuates within the parameters of the X and Y axes limits, as well as the initial 20mm stretch of the Z axis. It was particularly advantageous in my case for detecting defects in printed components like pulleys or shafts - faults that manifest specifically at particular intervals or only in certain print bed areas. However, it is imperative to commence with a leveled printing surface; the vertical and horizontal lines are 1mm apart.
