X-Y hole compensation

1-Print: Create a model with six circles (10mm, 15mm, 20mm,25mm,30mm and 35mm). Print it using your usual settings.2-Measure: Precisely measure the inner diameter of each circle in both X and Y directions.3-Error Calculation: Subtract the measured diameter from the designed diameter for each circle (ex: 30 - 29.95 = 0.05). This gives you the error.4-Average Error: Add all errors together and divide them by 6 (this gives you the average error).5-Radius Correction: Divide the average error by 2 to get the radius error.6-Compensation: Add this radius error to your printer's X-Y hole compensation setting (consult your printer's documentation for how to do this).
