Meet the Extruder E-Steps, Rotation Distance & Flow
Calibrate your 3D printer extruder: calculate new e-steps (M92 E) and Klipper rotation_distance from a 100 mm test, correct the flow multiplier from wall.

What is the Extruder E-Steps, Rotation Distance & Flow?
An extruder that pushes 96 mm of filament when asked for 100 mm under-extrudes by 4% — enough to cause weak walls and gaps. The e-steps test fixes that: mark the filament, extrude 100 mm, measure what moved, and the calculator returns the corrected steps/mm for Marlin and the corrected rotation_distance for Klipper, with the exact G-code to apply them.
Flow calibration uses a measured single-wall cube to correct the flow multiplier. The volumetric flow tabs show how much plastic per second your speed, layer height and line width need, compare it with typical hotend limits and give the maximum speed for any flow.

Questions people ask
What is rotation_distance?
Millimetres of filament per extruder motor revolution in Klipper.
What is a good flow value?
90–105% for most filaments.
Do I save with M500?
Yes in Marlin.
Is the hotend limit exact?
Limits vary by hotend and filament.
How do I use the Extruder E-Steps, Rotation Distance & Flow?
1. Do the 100 mm extrusion test. 2. Enter current value and measured remaining distance. 3. Apply the new value and save. 4. Calibrate flow with a single-wall cube.
