Thank you.
First thing I did was M206 - that displayed a Transformation Matrix (several values but nothing I needed).
Then, in Config.h I set Eeprom to 0 (it was 1) and uploaded. Received compile error saying sdeeprom error from HAL.h and requiring setting Eeprom to 1.
So, I'm not sure what M206 was supposed to do (regarding being able to reset filament print use to zero) as well as the eeprom error...
