Vref voltages on TMC2208 FAQ (E1 and E0 ?) #130

Hi. I'm trying to adjust the Vref of my TCM2288 drivers for the Anycubic Mega S but I'm confused. In the FAQ, it recommends voltages 1V on X, Z, E and 1.15V on Y and E0. But I don't understand since for the Mega S we have the engines: X, Y, Left Z, Right Z and E0. What would E1 referenced in the FAQ? Thanks.

E1 is the second Z axis. E0 is the extruder. Not sure if they updated it, but on the PCB you can see that the driver for Z2 is actually labeled E1.
