Z axis homing issues

I have a i3 (RAMPS 1.4 + Marlin) that is causing me issues.

When I manually control the Z axis from Repetier it's moving absolutely fine however as soon as I attempt to home the Z axis from Repetier the motors just whir and grind without actually moving.

I've checked all of the endstops and they operate fine.

Any ideas ?

Thank in advance

Craig

Homing feedrate in your firmware is too high by the sounds of it.

About half way down the config.h change

#define HOMING_FEEDRATE_Z (4*60)

too

#define HOMING_FEEDRATE_Z (2*60)

Just to post back - changing it worked fine for me.

Now just got to figure out what has happened to my Z endstop.... (it's never-ending)
