Limit for Z-axis speed

I am using postprocessing a.m. DeuxVis and Trying to adjust Z-axis speed. There is a hard limit at 294. 294 works fine without skipping steps, but when setting it to 295 the printer dies.
I have looked in firmware configurations.h, but have not found a limit there. Where is the limit defined? and can it be changed?

What do you mean by "The machine dies" ?

Anyway, I got those max values in my configuration.h :

//our maximum feedrates in mm/minute
#define FAST_XY_FEEDRATE 4800.0
#define FAST_Z_FEEDRATE  120.0

Most of my technical comments should be correct, but is THIS one ?
Anyway, as a rule of thumb, always double check what people write.

Communication with the printer gets impossible as if it waits for something, that never happens. I have to reboot to make it run again.
I have the same max-settings, but it changes nothing if I change:
FAST_Z_FEEDRATE 400
- so I thought it was not that parameter.
