The flushing volume setting is one of the settings that requires the most attention. If the models you will print have contrasting colors (such as too light and too dark), you should increase the flushing. If you do not increase it, color transitions will be seen in your model. You can adjust the color cleansing by increasing the multiplier or entering it manually.
Flushing volume has no special settings. The user must create his own flushing data.
