Re: Marlin 1.1.0-RC7 compile new value for Z offset but old value still exists

Now I do not have RC7 Marlin - Though I have Marlin 1.1.x RC6 and RC8

These numbers some times do not get overwritten with the Firmware Flash.
You will sometimes need to to a M502 //'Read Firmware Defaults
Followed by saving the defaults M500 //'Save Settings
This will then over write the EEProm settings that were not changed during the Flashing Process.

In order to accomplish this you must enable this line
#define EEPROM_SETTINGS // Enable for M500 and M501 commands

Or

Using Marlin you can change the Z-Offset Value from the LCD and save it using LCD "Store Settings"

To Change the Z-Offset
From Main menu Click
Select Control Click
Select Motion Click
Select Z-Offset change to desired value Click

To Save
From Main menu Click
Select Control Click
Select Store Settings Click

Before Adding a Proximity Sensor with an thumb screw adjustable slide mount.
I used this method to get the correct nozzle distance to the Bed to get the correct filament adhesion.
With Z-Offset numbers from 0.4mm to 1.8mm then it would move my End-Stop Switch and I would have to Adjust the Z End-stop switch and do a Manual bed level and start all over again.
