X & Y movements are backwards

After many tries I still cannot get my X and Y moving in the correct direction. The config below is what I'm using now, I know it's wrong (backwards) but at least it's working and I'm able to get some really cool prints going! Unfortunately, I have to reverse my object in 3ds Max which will be a problem in the future.
I'm sorry, I've tried changing these values, and moving X pin to the "Max" slot on my RAMPS board... nothing seems to work.
desperate.
thanks for the help!

Note: I've tried changing INVERT X dir to 1, the X HOME to 1, and moving my endstop pin to "Max" position on RAMPS. It all moves correctly, but then my Endstop (which is on the right side) does not work.

#define INVERT_X_DIR 0
#define INVERT_Y_DIR 0
#define INVERT_Z_DIR 1
#define X_HOME_DIR -1
#define Y_HOME_DIR 1
#define Z_HOME_DIR -1
#define X_MIN_POS 0
#define Y_MIN_POS 0
#define Z_MIN_POS 0

Have you tried rotating the motor connection on the ramps so that they are the other way around?
Most of the problems are because of connection being wrong.

You haven’t said what type of machine... ill presume I3 type machine
(other machines can move differently, eg K8200 type machines the bed move in X and Y, inverting the direction of movement in X)

re
#define INVERT_X_DIR 0
#define INVERT_Y_DIR 0
#define INVERT_Z_DIR 1

These define the direction of movement, they are different for each printer depending on stepper plug wiring.

So make it match the following movement:
X + moves the hotend to the right and X - moves the hotend to the left
Y + moves the bed towards the front and Y - moves the bed towards the back.
Z + moves the hotend up away from the bed and Z - moves the hotend down towards the bed

re
#define X_HOME_DIR -1
#define Y_HOME_DIR 1
#define Z_HOME_DIR -1

This set the location of the endstops
X:
If the end stop is on the left its a min endstop and should be set to -1 (NB on a ramps you need use the min endstop plug, this is the same for X,Y and Z)
If the end stop is on the right its a max endstop and should be set to 1 (NB on a ramps you need use the max endstop for plug,this is the same for X,Y and Z)
Y:
If the endstop is at the back its a min endstop and should be set to -1 (this confuses lots of people, but is reversed as its movement in relation to the hot end)
if the endstop is at the front its a max endstop and should be set to 1
Z:
If the endstop is at the bed its a min endstop and should be set to -1
if the endstop is at the top of travel its a max endstop and should be set to 1

re
#define X_MAX_POS 205
#define X_MIN_POS 0
#define Y_MAX_POS 205
#define Y_MIN_POS 0
#define Z_MAX_POS 200
#define Z_MIN_POS 0

These define the limits of travel. If using max endstops these must be accurate, as when it homes to max it then thinks it is at the MAX_POS

NB Position 0,0,0 is X Left, Y bed back, and Z down.
