Klipper extruder rotation distance
Calculate extruder rotation distance from requested and measured filament movement.
Results
- New extruder rotation distance
- 32.495 mm
Method
New rotation distance = current distance × measured extrusion ÷ requested extrusion.
Worked example
Example inputs
- Current extruder rotation distance
- 33.5 mm
- Requested extrusion
- 100 mm
- Measured extrusion
- 97 mm
Calculated outputs
- New extruder rotation distance
- 32.495 mm
How to read the result
With these example inputs, New extruder rotation distance is 32.495 mm. Use that value for the setting or decision named above, and read the other outputs as supporting checks.
Common mistake
Do not leave Current extruder rotation distance at the example value of 33.5 mm unless it matches your own measurement.
Assumptions and limits
Follow Klipper’s extruder measurement procedure. This is not a printed cube calibration and does not send commands to a printer.
