June 15: Calibrate Your E-Steps to Ensure Correct Filament Extrusion

Introduction

Can you calibrate E-steps for 3D printer? If your prints look under-extruded or bulky, your extruder steps per mm (E-steps) might need recalibration. Proper tuning ensures consistent extrusion flow for stronger, more accurate prints.

Why This Matters

Incorrect E-steps cause over-extrusion or under-extrusion, affecting dimensional accuracy and layer adhesion. Calibration fine-tunes filament flow to match expected values.

How to Apply This Tip

✅ Measure filament movement manually—extrude 100mm and check actual distance moved.

✅ Adjust E-step values in firmware—fine-tune with precise calibration.

✅ Re-test extrusion after updates—always confirm settings.

Slicer Settings: Cura & PrusaSlicer allow flow rate tuning, but firmware calibration is most effective.
