The formula to calculate the Steps Per MM is:
NS/MM=OS/MM⋅(100D)
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⋅(10050)=160
So, the new steps per MM (NS/MM) would be 160.
