Orca Slicer V-Shape Mode Pressure Advance Calibration Guide

This guide explains how to calibrate the pressure advance setting using V-Shape Mode in Orca Slicer. You will need to adjust settings in printer.cfg, print a calibration pattern, and fine-tune the pressure advance value based on the print results.

Preparation

1. Update printer.cfg:

   • Before starting the calibration, set pressure_advance to 0 in your printer.cfg file to ensure no pressure advance effect during the test.

     [extruder]
     pressure_advance = 0

Calibration Process

1. Slice the Model:

   • Slice the model with V-Shape Mode enabled. Review the complete calibration pattern in the preview interface to confirm it’s correctly set up.

1. Print the Calibration Model:

   • Print the calibration model with pressure_advance set to 0.

   • Examine the printed V-Shape pattern, especially the corners, for any signs of uneven extrusion or other issues.

Evaluation and Adjustment

1. Evaluate Print Results:

   • Assess the V-Shape pattern, focusing on the clarity and consistency of the corners.

   • Identify the pressure advance value that yields the best print quality.

1. Adjust pressure_advance:

   • Update the pressure_advance value in your printer.cfg based on the results:

     [extruder]
     pressure_advance = 0.03

2. Restart the Printer:

   • After updating the configuration, restart your printer to apply the new pressure_advance settings.

3. Reprint and Verify:

   • Reprint the calibration model to confirm that the new pressure_advance value has improved the print quality.

Finalizing Calibration

1. Confirm Results:

   • You can test the adjusted pressure_advance value by printing a VORON cube to check the sharpness and consistency of the corners.

2. Save Settings:

   • Once the calibration is satisfactory, save the settings for future prints.

By following these steps, you’ll effectively calibrate the pressure advance setting in Orca Slicer using V-Shape Mode, leading to improved print accuracy and quality.
