Y axis won't home

I re-flashed my Marlin1.1.9 and need some help. My y axis will not home It will start the print where ever it is sitting. If I manually push it onto the endstop it will then move about 15mm off of the endstop to start. How do I get it to home and then stay at the endstop? Geeetech I3 Pro B if the printer makes a difference.

Thanks

start with checking your endstops using M119 gcode

I suspect you will find that the Y endstop is already triggered when not home.

Ie make sure Y switch is not being touched, send M119, the Y endstop should say Open
Then hold down the Y endstop with a finger, send a new M119, the Y Endstop should say Triggered.

If it is reversed Invert your endstop. (how depends on what version of Marlin you are using)

OK. It shows triggered both ways. Upon inspection I found one of my wire ends was broken. When it worked before you messed with the firmware you don't look at mechanical/electrical problems.

Thank You!!!
