Marlin 1.1.3 on Prussa i2. issues with Z endstop config

Hi Ladies and Gents,

I had to re-do my config.h, figured might as well upgrade to Marlin 1.1.3 and be up to date.

I managed to configure everything but my Z axis. I can move it up / down manually but when homing it, it buzzes endlessly, I have to disconnect/reconnect to calm things down.
I figure it might be an endstop setting???

I am using simple switches, nothing fancy at the zmin.

I have included my whole config.h file, can someone offer me a second look, I'm too close to the problem to find it.

thank you kindly,

Marc

take a look at #define HOMING_FEEDRATE_Z (4*60)

if your using m8 rods you cant go any faster that about (2*60) maybe even (1*60), been a long time since I used m8 rods

I had just gone to bed, but couldn't sleep, this thing was on my mind.

You sir are a champion ! Right on. (2*60) works like a charm. I would never figured the Homing speed could have caused issues, never figured such a change on torque.
Very impressive.

Thank you !

Now on to calibrate the whole thing... I love this new version (I was on 1.0)
