EEProm is off by my default to prevent nonsense like that as that stung me when I first got into 3d printers and I said never again so I turned it off.Quote

I have had problems after flashing if I did not reload firmware defaults. You can do this by simply. sending a M502 then sending M500.
Or you can send a M502 ( Factory Reset ), M501 ( Restore Settings ) and then M500 ( Save Settings ).
Not sure why but the old setting are not always cleared when flashing, not resetting can lead you to experience some unwanted side effects)
:NOTE this can only be accomplished if you enable ( EEProm )
I did "you can send a M502 ( Factory Reset ), M501 ( Restore Settings ) and then M500 ( Save Settings )" and M500 said that the prom was disabled (good). I then sent the G28 X and up goes Z so nothing changed.
