Marlin configuration:

#define MICROSTEPPING_RATIO 0.0625 // Enter microstepping ratio of electronics. Printrboard and Pololu = 1/16, Gen6 = 1/8, etc.
#define XY_MTR_STPS 200 // Enter number of steps per one revolution of the X and Y motors. See motor datasheet, 1.8degree = 200 steps, 0.9degree = 400 steps
#define Z_MTR_STPS 500 // Enter number of steps per one revolution of the Z motor(s). gear ratio 50/20=2.5  200X2.5=500
#define EXTRUDER_MTR_STPS 200 // Enter number of steps per one revolution of the extruder motor. Default is 200

#define PACKING_DENSITY 1.0 // Leave at 1.0 and adjust in Skeinforge 40+. Alternatively, leave at 1.0 in Skeinforge and calculate manually: Packing_Density = (NozzleDiameter^2)/(Measured_Extruded_Filament_Diamter^2)
#define BOLT_DIAMETER 17.00 // Enter measured diameter of hobbed bolt or pinch wheel
#define EXTRUDER_GEAR_RATIO 60/12 // Enter gear ratio of extruder. Wade’s Extruder: 39/11, Accessible Wade’s by Greg Frost: 43/10, Adrian’s Extruder: 59/11, etc.

#define BELT_PITCH 2.032 // Enter pitch of X and Y belts in millimeters (space from tooth to tooth). XL belts = 5.08mm
#define GEAR_TEETH 20 // Enter number of teeth on X and Y gears
#define Z_ROD_PITCH 1.25 // Enter pitch of Z rods in millimeters. Pitch = 1.25mm for directly driven M8 rods.
// ************* End MECHANICAL Calibration *************

#define PI 3.14159265359
#define DEFAULT_AXIS_STEPS_PER_UNIT {((XY_MTR_STPS/MICROSTEPPING_RATIO)/(BELT_PITCH*GEAR_TEETH)), ((XY_MTR_STPS/MICROSTEPPING_RATIO)/(BELT_PITCH*GEAR_TEETH*1.9)), ((Z_MTR_STPS/MICROSTEPPING_RATIO)/Z_ROD_PITCH),((PACKING_DENSITY*EXTRUDER_MTR_STPS*EXTRUDER_GEAR_RATIO*(1/MICROSTEPPING_RATIO))/(PI*BOLT_DIAMETER))}  //The  Y axsi GEAR_TEETH*1.6 due to GEAR_TEETH  is 20 but Y Axis is 38 ,so multiply by 1.9 ,20X1.9=38
#define DEFAULT_MAX_FEEDRATE {500, 500, 5, 45} // (mm/sec)
