Z safe homing

[adamfilip]

using RC7 Bugfix I have enabled Z home homing, but its not moving the gantry to the middle of the bed.

my printer homes to Y max instead of Y Min, not sure if this is causing an issue

my travel limits are

#define X_MIN_POS 0
#define Y_MIN_POS 0
#define Z_MIN_POS 0
#define X_MAX_POS 310
#define Y_MAX_POS 300
#define Z_MAX_POS 300

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

Ah yes.... There's a bug in Z_SAFE_HOMING. If your probe is outside the bed when you try to use it, it will not perform the move. The problem is this test:

float cpx = RAW_CURRENT_POSITION(X_AXIS), cpy = RAW_CURRENT_POSITION(Y_AXIS);
if (   cpx >= X_MIN_POS - (X_PROBE_OFFSET_FROM_EXTRUDER)
    && cpx <= X_MAX_POS - (X_PROBE_OFFSET_FROM_EXTRUDER)
    && cpy >= Y_MIN_POS - (Y_PROBE_OFFSET_FROM_EXTRUDER)
    && cpy <= Y_MAX_POS - (Y_PROBE_OFFSET_FROM_EXTRUDER)) { . . .

To fix the issue, change the first line to:

float cpx = RAW_X_POSITION(destination[X_AXIS]), cpy = RAW_Y_POSITION(destination[Y_AXIS]);

I have a patch pending for RCBugFix that will be merged today.
