Klipper Pressure Advance

For an in-depth guide, visit the official Klipper documentation: https://www.klipper3d.org/Pressure_Advance.html

*Pressure advance is only supported for filament based printers

*Semi-auto calibrations are supported in re:3D Klipper OS as of v1.3.0

1. Start off by entering global parameters based on your printer type and material. Make sure to click 'Set Parameters' to activate the profile. 

   

2. Scroll down to the Pressure Advance section. 

   

3. Click 'Start Calibration' to begin printing the test artifact based on the global parameters. You can navigate back to 'Printer Control' to check progress.
4. Wait for the print to finish. It's also okay to cancel the print if quality starts to get worse. 

5. The corners of each wall is what we are interested in measuring. A finished print will look something like this:

    

6. Inspect the print and use digital calipers to measure (mm) the height that has the best quality corners. When in doubt, prefer a lower height. 

   

7. When you've obtained a measurement, multiply that number by 0.005 (measurement in mm * 0.005). This will give you the pressure advance value. 
8. Input this value into the 'Pressure Advance' calibration section and submit results.
