Updating firmware question

[Holy1]

If I make a change in the configuration h file and upload it will I have to do the calibration over again? Or can I export my eeprom first then import it afterward? I want to do minor changes to see their effect and then switch them back.

Thanks

If you're using Repetier host, yes you can save and reload the eeprom file through it and save your calibration settings.

I am not entirely sure of this but if you do not change the number of the eeprom in configuration.h the eeprom should not be changed?
