How to set the K-factor for Pressure Advance

The K-factor is a 3D printing calibration parameter that adjusts extrusion during acceleration and deceleration. It prevents over- or under-extrusion in corners and details. This article shows how to configure it to improve print quality.

BCN3D materials come with a pre-configured K-factor to ensure optimal print quality. However, when using custom materials, you need to set this parameter correctly to achieve the best results.

After configuring the temperature and alias for your custom material, you will be able to enter its K-factor value. The printer will always display a recommended standard K-factor for these materials, so you can try this value first before making any adjustments. Here you can find an STL file to test the value.

Omega I60 uses a specific conversion system for the K-factor. Therefore, standard Marlin values should not be entered directly.

If the results with the preset value (0.0007) are not ideal for the loaded material, you can always adjust the values in ±0.0001 increments until you achieve the desired result.

Bear in mind that the pre-configured K-factor values for BCN3D materials cannot be modified; this option is only available for custom materials.
