I changed the value of the 'Z length' in the configuration tool and upload the firmware after downloaded the new configuration.h.
But after connect the host, the value of the Z (at the LCD or at the host) is not changing, remain prior the changing value.
I wonder why this is happening. I am using Eeprom setting 1, fyi (since somehow I think this is eeprom related).
Is there anyway to let the changing through the configuration tool really effect the system?
