## Steps Per MM Formula

The following formula is used to calculate the steps per MM on a 3-D printer.

NS/MM = OS/MM * (100 / (D) )

- Where NS/MM is the new steps per MM
- OS is the old or current steps per MM
- D is the distance the filament traveled (mm)

## What are steps per MM?

Definition:

Steps per MM are a measure of the amount of distance in millimeters that a 3-D printer travels per step made by the printer.

## How to calculate steps per MM?

Example Problem:

The following example outlines how to calculate steps per mm.

First, determine the previous or old steps per mm. In this example, the old steps per mm were 85 steps per mm.

Next, determine the total distance traveled. In this case, the total distance traveled is measured to be 120mm.

Finally, calculate the new steps per mm using the formula above:

NS/MM = OS/MM * (100 / (D) )

NS/MM = 85* (100 / 125)

NS/MM = 68 steps per mm
