To calculate steps per millimeter, multiply the steps per rotation by the pulley circumference and adjust for the stepper driver microsteps.
The Steps Per MM Calculator is a vital tool for fine-tuning 3D printers, CNC machines, and other motion-controlled systems. It ensures precise movements of motors, enabling accurate positioning in tasks like 3D printing, machining, and laser cutting.
Whether calibrating an MK8 extruder, Marlin firmware, or an Ender 3 printer, this calculator optimizes motion parameters for toothed belts, lead screws, or ball screws. By adjusting steps per millimeter, you achieve consistency in extrusion rates and movement distances, improving print quality and machine performance. Perfect for hobbyists and professionals, it simplifies motor calibration and guarantees reliability.
Formula
NS/MM = OS/MM ∗ (100 / D)
| Variable | Definition |
|---|---|
| NS/MM | New Steps Per Millimeter |
| OS/MM | Old Steps Per Millimeter |
| D | Actual Distance Measured (in mm) |
Solved Calculations
Example 1
Adjust the steps per millimeter for a 3D printer with an original value of 100 steps/mm, where the actual distance moved is 95 mm.
| Variable | Value |
|---|---|
| Old Steps Per MM (OS/MM) | 100 |
| Actual Distance (D) | 95 mm |
| New Steps Per MM (NS/MM) | 105.26 steps/mm |
Example 2
For a CNC machine, calculate the new steps per mm if the original setting is 200 steps/mm but the machine moved 97 mm instead of 100 mm.
| Variable | Value |
|---|---|
| Old Steps Per MM (OS/MM) | 200 |
| Actual Distance (D) | 97 mm |
| New Steps Per MM (NS/MM) | 206.19 steps/mm |
