Prusa I3 Mk2 Homing offset

Hello, I am using the latest Prusa I3 Mk2 Firmware.

I changed the Endstop of my X Axis. Whenever I go in the menu to start position my printer is homing and is going to an offset

X 12
Y -1.9
Z 0.1

How can I edit the X Offset ?? I cannot find anything in the marlin firmware with this offset :/. I need to adapt this X offset to 5 mm
Please dont advise me to change my X Endstop to original thanks

Re: Prusa I3 Mk2 Homing offset

In Configuration_Prusa.h:


// Home position
#define MANUAL_X_HOME_POS 0
#define MANUAL_Y_HOME_POS -2.2
#define MANUAL_Z_HOME_POS 0.15

// Travel limits after homing
#define X_MAX_POS 250
#define X_MIN_POS 0
#define Y_MAX_POS 210
#define Y_MIN_POS -2.2
#define Z_MAX_POS 210
#define Z_MIN_POS 0.15

change those values.

What you need to do is change X_MIN_POS to the value of X when the endstop is hit. You might not want or need to change the actual home position; it's a bit arbitrary.
