home command issue

I have recently built a prusa i3 clone (basically followed the youtube videos by Tom Sanladerer) however when I give the home command, the home position of the bed means that when the z-axis homes, the bed is too far back and the probe is missing the bed and won't trigger, with the extruder being lowered too far and crashing into the bed.

Is there a change I can make to make sure the home position of the bed is forward of the end-stop position when it stops?

move you Y endstop so when it homes it stop at Y0

Is there a way to do it in the firmware? I considered moving the endstop but that is a much trickier job if there is an easier way.

What firmware are you using ?

I'm using Marlin

In configuration.h uncomment the following line (remove // )
//#define Z_SAFE_HOMING

this should move the nozzle to the centre of the bed after X and Y are homed and then home Z
