E-steps calculator
Mark the filament, ask the printer to push 100 mm, and measure what is left to the mark. You get the new E-steps value and the G-code to save it.
How to measure
- Heat the nozzle to your normal printing temperature.
- Mark the filament 120 mm above where it goes into the extruder.
- Send
M83, thenG1 E100 F100. It pushes 100 mm slowly. - Measure from the same spot to the mark again, and type it below.
Your extruder
G-code to send
M92 sets the new value, M500 saves it so it stays after a restart. Then run the test again: it should push 100 mm, give or take 1 mm. A change of more than 15% usually means a slipping gear or a blocked nozzle, not a setting.
Worked example
Current value 93, mark at 120 mm, ask for 100 mm, 23 mm left. It pushed 120 - 23 = 97 mm, so the new value is 93 x 100 / 97 = 95.88. Send M92 E95.88, then M500.
How it works
- Really pushed = mark - what is left.
- New E-steps = current x asked / really pushed.

Questions
Should the nozzle be hot?
Yes. Heat it to your normal printing temperature so the extruder pushes through melted plastic, and extrude slowly (F100 is 100 mm a minute) so pressure does not skew the result.
My printer has no E-steps setting. What now?
Klipper uses rotation_distance instead: new = old x really pushed / asked. Many sealed printers, for example Bambu Lab ones, set up the extruder for you and have nothing to change.
Is this the same as flow?
No. E-steps makes 100 mm asked come out as 100 mm pushed, for the whole printer. Flow is a slicer setting per filament, tuned after E-steps. Use the flow rate calculator for that.
