Saving G29 Bed Level Correction Matrix to EEPROM

[Roxy]

...
When I now try to home x or do a G28 the machine moves away from above position into the wall or out over the limits. In other words, wherever on the bed z is triggered,
the machine acts as if x and y are home.

If no G29 is performed, all works good. I also have to say that everything worked withe that same fw, flawlessly for weeks, until I changed the z offset on a viki lcd to not
have to change it in the fw and flash. Ever since I have this phenomenon. I swapped boards, unplugged the viki, changed firmware and believe it or not, a second machine with the same setup is now having similar issues.

...

What could I be missing?

We are fighting a similar issue in this thread: http://3dprintboard.com/showthread.p...lling-Glitches

If you scroll to the end, I have some debug code inserted into his Marlin_main.cpp file. I suspect we are going to get his problem figured out pretty quickly. And there is a fair chance his problem is the same as your problem.

Fri, can you post your Configuration.h file? I want to check something.
