Flow Rate Calibration Calculator
Calculate the correct flow rate multiplier from measured versus expected extrusion width.
How We Calculate This
Formula
- Corrected flow = (Expected width / Measured width) x Current flow rate
- Over-extrusion = ((Measured - Expected) / Expected) x 100%
If your measured width is wider than expected, you are over-extruding and need to reduce flow. If narrower, increase flow. The goal is to match the slicer's expected line width.
