E-Steps Calculator
Calculate the correct extruder steps/mm (e-steps) for your 3D printer. Fix under-extrusion and over-extrusion in seconds.
E-Steps / mm Calculator
Find in your firmware: M503, or Marlin Configuration.h
Mark 100mm from extruder entry and command: G1 E100 F100
Measure how much filament actually moved from your mark
How to Calibrate E-Steps on Your 3D Printer
- 01
Mark your filament
Make two marks on the filament: one at the extruder entry and another 120mm above it. Use a marker or tape.
- 02
Record current e-steps
Connect to your printer via USB and send M503. Note the E value (e.g., M92 E93.00). Enter this in the calculator above.
- 03
Heat and command extrusion
Heat your hotend to printing temperature. Send: G92 E0 then G1 E100 F100. Wait for the extrusion to complete.
- 04
Measure what extruded
Measure from the extruder entry to your remaining upper mark. Subtract from 120mm to find what actually extruded.
- 05
Calculate and set
Enter the value in the calculator above. Copy the result and send: M92 E[result] then M500 to save to EEPROM.
