M499 - EEPROM Invalidate Command

[3Dave]

Hi, first post from a new member. I realise this thread is old but I'm using Marlin 1.1.4 and I was wondering if this EEprom Invalidator is still valid and/or even necessary. It could explain why I am having trouble changing my Z-steps. I have one of those cheap Chinese printers from Amazon, a great introducer to 3D printing as you have to learn fast in order to get anything printed.

Hello

I look in the
G-Code and M-Code Grand Master List

M499 is not on the list.
