Calibration Circles to Test for X-Y distortion

Print these two rings side-by-side about 3mm off of the build plate, ensuring they're oriented with the embossed "Y" facing towards the Y-axis on both sides. These are 36mm in outer diameter and can be utilized to measure X and Y distortion as well as correct it using the firmware's settings for "X Size" and "Y Size". I suggest creating a spreadsheet to track these tests. If the inner ring remains stationary within the outer ring, this indicates that the x and y axes are accurately aligned. You may need to adjust your model to account for any scaling discrepancies. It is recommended to fully cure the parts before taking measurements so that shrinkage is complete.
