01 / METHOD
How to use this e-steps calibration tool
- Mark and measure filament using your printer’s documented cold or hot extrusion procedure.
- Enter current E-steps, commanded extrusion, and actual filament movement.
- Apply the calculated value using the correct firmware procedure, then repeat the measurement.
02 / APPLICATIONS
When it is useful
- Calibrate a replaced extruder
- Verify steps after gearing changes
- Diagnose consistent under- or over-extrusion mechanics
03 / MODEL
Assumptions and limitations
Assumptions
- Actual movement is measured accurately.
- The extruder does not slip and the command completes.
- Firmware uses a steps-per-millimeter calibration value.
Limitations
- This does not calibrate slicer extrusion multiplier, pressure advance, temperature, or filament diameter.
- Incorrect firmware commands or saving procedures can cause unsafe motion; consult your printer documentation.
04 / FAQ
Common questions
What formula is used?
New E-steps = current E-steps × commanded distance ÷ actual distance.
Should I extrude through the hotend?
Follow your manufacturer’s method. Measuring through a hotend includes back-pressure effects; a disconnected path isolates extruder mechanics.
Do I need to repeat the test?
Yes. Re-measure after applying the value and avoid changing several calibration variables at once.
