Sovol SV06 extrusion calibration (e-steps)

The stock Sovol SV06 e-steps is 691.5 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 SV06’s planetary-gear direct drive needs far more steps per millimeter than a Bowden machine — Sovol’s open-source Marlin ships 691.5, the highest stock value in this table. This default comes from the manufacturer’s own firmware or config. Source.

How to calibrate on the Sovol SV06

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 691.5 and 97 mm measured: 691.5 × 100 ÷ 97 = 712.89. Under-extrusion pushes e-steps up. The calculator does this arithmetic for you.
5. Apply and save. Send M92 E712.89, 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 Sovol SV06

A value this high looks wrong if you are used to Ender numbers — it is not. The planetary gearbox multiplies motor revolutions, so ~690 steps/mm is exactly where this extruder should live.

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.
