The Klipper Rotation Distance Calculator is an invaluable tool designed to help users of the Klipper firmware accurately calculate the necessary steps their stepper motor needs to perform specific movements. This calculator simplifies the process of configuring printers or CNC machines that use the Klipper firmware, ensuring precision and efficiency in operations.
Understanding the Calculator’s Purpose and Functionality
The Klipper Rotation Distance Calculator’s primary purpose is to compute the exact number of steps a stepper motor must take to achieve a desired rotational distance. This is crucial in applications like 3D printing and CNC machining, where precise movements are fundamental to the accuracy of the final product.
Inputs and Formula
The calculator uses three main inputs:
- Current Steps/mm (S): This is the existing configuration of how many steps the stepper motor takes to move one millimeter.
- Microstepping Setting (MS): This setting dictates how many microsteps the motor driver uses to divide a full step. Higher microstepping increases resolution and smoothness.
- Desired Rotation Distance (D): The distance, typically in millimeters, that you want the axis to move.
The calculations follow these steps:
- Steps per Revolution (SPR): Calculate the total number of steps for one full revolution, using
SPR = 200 * MS. - Rotation Distance in Steps (RDS): Determine how many steps are needed to cover the desired distance, with
RDS = D * S. - Required Movement in Steps (RM): Divide the rotation distance in steps by steps per revolution to find out the actual steps needed,
RM = RDS / SPR.
Step-by-Step Examples
Let’s calculate the steps required for a stepper motor to rotate an axis by 360 millimeters:
- Current Steps/mm (S): Assume 80 steps/mm.
- Microstepping Setting (MS): Using a microstepping setting of 16.
- Desired Rotation Distance (D): Desired movement is 360 mm.
Using the formulas:
- Steps per Revolution (SPR):
SPR = 200 * 16 = 3200steps/revolution. - Rotation Distance in Steps (RDS):
RDS = 360 * 80 = 28800steps. - Required Movement in Steps (RM):
RM = 28800 / 3200 = 9steps.
Therefore, the motor must execute 9 steps to achieve the desired 360 mm movement.
