Re: Marlin homing problem

Have done this

"should be
// 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

now if it homes in the wrong direction you have to invert the axis direction, not the homeing direction. ie play with the following as needed
#define INVERT_X_DIR true
#define INVERT_Y_DIR true
#define INVERT_Z_DIR false"

for my sanity Im happy working out 1 axis at a time cause once I get one the other 2 will follow.....so after setting the above...and setting home direction correctly on X axis...

X travels in correct direction
m119 shows x max triggered
switch is plugged into ramps 1.4 x+ pins
when I home x wants to over run the axis.

#define INVERT_X_DIR true    // for Mendel set to false, for Orca set to true
#define INVERT_Y_DIR true   // for Mendel set to true, for Orca set to false
#define INVERT_Z_DIR false   // for Mendel set to false, for Orca set to true
#define INVERT_E0_DIR false   // for direct drive extruder v9 set to true, for geared extruder set to false
#define INVERT_E1_DIR false    // for direct drive extruder v9 set to true, for geared extruder set to false
#define INVERT_E2_DIR false   // for direct drive extruder v9 set to true, for geared extruder set to false

// 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 min_software_endstops true // If true, axis won't move to coordinates less than HOME_POS.
#define max_software_endstops true  // If true, axis won't move to coordinates greater than the defined lengths below.

// Travel limits after homing
#define X_MAX_POS 0
#define X_MIN_POS 200
#define Y_MIN_POS 0
#define Y_MAX_POS 210
#define Z_MAX_POS 180
#define Z_MIN_POS 0

#define X_MAX_LENGTH (X_MAX_POS - X_MIN_POS)
#define Y_MAX_LENGTH (Y_MAX_POS - Y_MIN_POS)
#define Z_MAX_LENGTH (Z_MAX_POS - Z_MIN_POS)

thanks for your time
