How to Calculate X_STEPS_PER_INCH, X_STEPS_PER_MM and X_MOTOR_STEPS

#1

Hi All,

I have checked out the latest plotter 2.0 code: GcodeParser.ino and would like to know how these numbers get calculated:

float X_STEPS_PER_INCH = 48;
float X_STEPS_PER_MM = 40;
int X_MOTOR_STEPS = 100;

Many thanks

Hi Franklee,

We calculated it base on 1/8 Microstep Resolution.
