Creality CR-10 extrusion calibration (e-steps)

The stock Creality CR-10 e-steps is 95 steps/mm. That is the factory e-steps value — tune it once with the mark-and-measure test and the extruder tracks reality. The rotation distance & e-steps calculator does the correction math and prints the exact line to paste; the full calibration guide explains the test in detail.

The CR-10 ships with 95 steps/mm — not the 93 of its Ender cousins, a difference that trips people moving between the two families. This default comes from the manufacturer’s own firmware or config. Source.

How to calibrate on the Creality CR-10

1. Heat the hotend to normal print temperature and mark the filament exactly 120 mm above the extruder inlet with a ruler and a fine marker or tape flag.
2. Extrude 100 mm slowly. From a console send G91, then G1 E100 F60 — slow, so back-pressure does not skew the measurement.
3. Measure what actually went through. Measure from the inlet to the mark again — actual extrusion is 120 − remainder (23 mm remaining means 97 mm extruded).
4. Compute the new value. new e-steps = old × requested ÷ actual — with the stock 95 and 97 mm measured: 95 × 100 ÷ 97 = 97.94. Under-extrusion pushes e-steps up. The calculator does this arithmetic for you.
5. Apply and save. Send M92 E97.94, then M500 to store it in EEPROM — without M500 the value is gone after the next power cycle.
6. Confirm. Repeat the test once; the mark should land 20 mm from the inlet. Within about ±0.5 mm is measurement noise, not a reason to iterate.

Notes for the Creality CR-10

Start from 95, not 93. The CR-10’s Bowden path is one of the longest on a mainstream printer, so expect the calibrated value to drift upward a few points from stock.

Thinking about Klipper on this machine? The same test applies after the conversion, but the value becomes rotation_distance and the formula inverts — the Klipper extrusion calibration guide covers that side.
