Flow Rate Calibration

 · Besides this, flow rate calibration can also improve retraction values a bit, and help with bulging corners and layer seam. If the extruder steps are properly calibrated, the flow rate value should be really close to a single digit value (1.00). Flow Rate Calibration Prerequisites. In order to do an accurate flow rate calibration, the Extruder ...
