Hi Cameron,
thank you for advice. I want to try milling. I know that it is danger, I am going to be carefull :)

//-----------------------------------------------------------------------
//// ENDSTOP SETTINGS:
//-----------------------------------------------------------------------
// Sets direction of endstops when homing; 1=MAX, -1=MIN
#define X_HOME_DIR -1
#define Y_HOME_DIR -1
#define Z_HOME_DIR -1

//#define ENDSTOPS_ONLY_FOR_HOMING // If defined the endstops will only be used for homing <-- Uncomment this

const bool min_software_endstops = false; //If true, axis won't move to coordinates less than zero.  <-- Make sure this is set to false
const bool max_software_endstops = true; //If true, axis won't move to coordinates greater than the defined lengths below.

Be careful though, this will allow your Z axis to crash, and could damage your printer. Why do you want to be able to move past the endstop in Z?

Hello, does anybody know, how to allow minus direction of Z axis on Arduino with Sprinter ? With direction I mean under endstop.
