Meaning of this Code

Hello All,

I was wondering if anybody knew what the following code meant in terms of what task it will make the 3D printer perform;

// Effective X/Y positions of the three vertical towers.
#define SIN_60 0.8660254037844386
#define COS_60 0.5
#define DELTA_TOWER1_X -SIN_60DELTA_RADIUS // front left tower
#define DELTA_TOWER1_Y -COS_60DELTA_RADIUS
#define DELTA_TOWER2_X SIN_60DELTA_RADIUS // front right tower
#define DELTA_TOWER2_Y -COS_60DELTA_RADIUS
#define DELTA_TOWER3_X 0.5 // back middle tower
#define DELTA_TOWER3_Y DELTA_RADIUS

Thanks!

It's just a bunch of definition - so no tasks done from this. It just associates some values to some names to be replaced probably further down in the code you did not post

It's traditional to enclose expressions in #define directives with parenthesis. This helps avoid problems caused by operator precedence.
