The formula to calculate the Steps Per MM is:
\[ NS/MM = OS/MM \cdot \left( \frac{100}{D} \right) \]
Where:
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.
Let's say your old steps per MM (OS/MM) is 80 and the distance traveled (D) is 50 mm. Using the formula:
\[ NS/MM = 80 \cdot \left( \frac{100}{50} \right) = 160 \]
So, the new steps per MM (NS/MM) would be 160.
