Adjusting Z offset with BLTouch and Ramps 1.4

Thanks to Jeff I was able to get my MP3DP up and running with the BLTouch. I really like the three point bed sensing before each print but I am having issues with getting the Z dialed in.

Can someone help me figure out how to save the Z offset after I adjust it in the advanced settings?

In the lcd, configuration, save settings. Or M500 (IIRC) on the terminal.

I get an error saying eprom (or something) similar disabled when I try m500 and the LCD does not have a save option

You need to enable EEPROM in the firmware and reflash your board. Look for

#define EEPROM_SETTINGS // Enable for M500 and M501 commands

in configuration.h and uncomment it.

Thank you! All the help is appreciated
