E-Steps Calculator

Calibrate your extruder steps per mm to fix under-extrusion or over-extrusion.

E-Steps Calibration
Your current firmware value (M92 E value). Default for most Creality printers is 93.
How much filament you commanded to extrude (usually 100mm).
Measured amount of filament actually extruded.

G-Code Command

Send the G-Code command to your printer, then run M500 to save to EEPROM.

How to Calibrate E-Steps (Step-by-Step)

E-Steps calibration ensures your extruder pushes exactly the right amount of filament. This is one of the most important calibrations for print quality.

Step 1: Check Current E-Steps

Connect to your printer via terminal (OctoPrint, Pronterface, etc.) and send M503. Look for the line starting with M92 — the E value is your current E-Steps.

Step 2: Mark the Filament

With filament loaded, measure and mark 120mm from where filament enters the extruder (measure from the top of the extruder body).

Step 3: Extrude 100mm

Heat your hotend to printing temperature. Then send:

Step 4: Measure

Measure from the extruder body to your mark. Subtract from 120mm to get your actual extrusion length. If it extruded perfectly, 20mm should remain.

Step 5: Calculate & Apply

Enter your values above. Send the resulting M92 E[value] command, then M500 to save.

Formula

New E-Steps = Current E-Steps × (Requested Length ÷ Actual Length)
