Z steppers in series on E1, now they move seperately

Hi Everyone,
Alan from London been into 3d printing about 6 months now, built my anet a8 updated noe to bowden hotend and 2 mosfets
and updated the Y carriage.
But there my bubble went bang, now my Z motors move up and down one after the other.I,ve tried different drivers but without
any change, tried reflashing firmware, checking the cables but to no avail. What am I missing that would make my world all
shiny and glittery once again.

Any help appreciated. Alan

Let's Start with What Version of Marlin are you using?

Can you upload your Configuration.h, Configuration_Adv.h file to a online Storage Like Google drive and post a link so we can examine.
