Klipper Calculators

Klipper Rotation Distance Calculator

This tool helps you calculate the exact rotation distance required for your stepper motors, ensuring precise filament extrusion. Simply input the necessary parameters, and get the exact rotation distance for your 3D printer.

Instructions:

  1. Pre-heat nozzle and confirm filament is loaded and extruding correctly.
  2. Measure 110mm from the extruder body and place a mark on the filament.
  3. Request the extruder to extrude 100mm of filament.
  4. Measure from the extruder body to your mark. Minus 10mm. This is your actual extrude distance.
  5. Enter the previous rotation distance from your printer.cfg.
  6. Enter the actual length of filament that extruded in mm.
  7. Enter the requested extrude distance in mm.
  8. Click Calculate.
  9. View the result below the form.

Result:

New Rotation Distance: 19.950

Stepper Current Calculator

Optimize your 3D printer's performance with our Stepper Current Calculator. This tool helps you calculate the exact current settings required for your stepper motors, ensuring optimal performance and efficiency. Simply input the necessary parameters, and get the precise current settings for your 3D printer.

Though we do recommend calculating your own currents to input into your printer.cfg, you can find a list of all the most popular and common steppers (ldo, e3d, creality) here on github thanks to andrewmcgr.

Instructions:

  1. Enter the Motor Rated Current in Amps.
  2. Enter the Desired Current Percentage.
  3. Click Calculate.
  4. View the result below the form.

Result:

Calculated Run Current: 1.45 A

Klipper Belt Tension Calculator

Achieve optimal 3D print quality by properly tensioning your printer's belts. This calculator helps you convert belt frequency measurements to proper tension values, ensuring consistent, accurate prints with minimal artifacts.

How to Use:

  1. Download a frequency measuring app on your smartphone (like "Sound Analyzer" or "Spectroid").
  2. Pluck the belt like a guitar string while recording with the app.
  3. Note the frequency (Hz) measurement.
  4. Enter the belt type, span length, and measured frequency below.
  5. Get the recommended tension and adjust your belts accordingly.
Measure the distance between pulley centers

Results:

Enter your belt measurements and click Calculate to see results.

Recommended Belt Tension Ranges

For optimal performance in Klipper 3D printers:

  • CoreXY printers: 100-120 Hz for GT2 6mm belts over 400mm span
  • Cartesian (Ender, etc.): 85-105 Hz for GT2 6mm belts over 300mm span
  • Delta printers: 110-130 Hz for GT2 6mm belts

Note: Higher frequencies mean tighter belts. Too tight can damage bearings and motors, too loose causes print artifacts.
