X-Y Hole & Contour Test

Introduction

Calibration Guide: Using This Model to Adjust X-Y Hole and X-Y Contour Compensation.

1. Initial Print

For your first test, print the model using the printer's default settings without any adjustments.

2. Measure Dimensions

Use a caliper to measure the following two dimensions:

• X-Y contour compensation
  The ideal measurement should be approximately 75mm x 35mm.
• X-Y hole compensation
  The diameter error should be consistently minimal across all holes.

1. Elephant foot (over-extrusion at the bottom layer) may cause measurement errors. To minimize this, perform multiple measurements and measure from the top surface of the model using the caliper.
2. Always enable Precise Z height, as it is a critical setting to ensure vertical accuracy during printing.

3. Calculate Compensation Values

• Divide the observed error by 2 and input the results into the X-Y hole compensation and X-Y contour compensation settings.
• If you can estimate the Elephant foot error during repeated measurements, you can include this adjustment in your compensation values.

4. Reprint and Verify

Reprint the model using the updated compensation values, and measure again to confirm the dimensions are close to the design specifications. Repeat the process as needed until the calibration is complete and the desired accuracy is achieved.
