My weekend project was updating my Makerfarm i3v12 with Marlin and ABL. G28 and G29 work great from the terminal, but when I tried to run my bed leveling gcode from the sd card the printer tries to probe the Z at X0, Y0. I have Z_SAFE_HOMING set as follows, so I am confused. Can you give me a quick pointer where I have gone astray?
#define Z_SAFE_HOMING // This feature is meant to avoid Z homing with probe outside the bed area.
// When defined, it will:
// - Allow Z homing only after X and Y homing AND stepper drivers still enabled
// - If stepper drivers timeout, it will need X and Y homing again before Z homing
// - Position the probe in a defined XY point before Z Homing when homing all axis (G28)
// - Block Z homing only when the probe is outside bed area.
#ifdef Z_SAFE_HOMING
#define Z_SAFE_HOMING_X_POINT (X_MAX_LENGTH/2) // X point for Z homing when homing all axis (G28)
#define Z_SAFE_HOMING_Y_POINT (Y_MAX_LENGTH/2) // Y point for Z homing when homing all axis (G28)
#endif
