This sounds like the usual max z feedrate being set too high in the configuration.h in marlin default firmware
ie
#define DEFAULT_MAX_FEEDRATE { 300, 300, 5, 25 }
try reduceing the 5 to a 2 and recompiling firmware

Melzi's are a PITA
You have to add the sanguino. support to the arduino IDE, as it doesn't come with it...
But before you go that that extreme Just adjust the max fead rate of Z in eeprom
ie send this to the printer
M203 Z2 M500
The first line sets the Z max feed rate to 2
the second saves this to eeprom. (as long as it replied ok)
If you still want to compile the firmware see this [dustsreprap.blogspot.com]
Its still the same for all newer arduino IDE's
as for what cpu is either a 644p or a 1284p
Look at the number of the large black chip
if its a 644p it crap, not enough flash memory to run current marlin,
even the 1284p is getting tight (can't enable all features)
