Extruder Calibration Calculator

Fix over- or under-extrusion by comparing what you commanded with what actually came out — then get the right Marlin E-steps or Klipper rotation_distance, without guessing the math.

Correction factor

1.2×

This correction is larger than 10%. Re-measure to rule out a slipping extruder, wrong steps-per-mm, or a firmware issue before applying it.

M92 E111.6

Apply at your own risk — always extrude 100 mm and confirm before printing.
