Dual Head Extruders

On a Taz 6, what head is the one that lines up to autolevel the Z height?

Thanks

You can enter the g-code

G28 ;homes all 3 axes
G29 ;auto levels bed

to find out. However, it shouldn’t really matter. We only care about the relative z-height between the extruders. If they’re the same, both will be level no matter what. If they’re different, they’ll both be level (parallel to the build surface), but one will be offset by a constant amount.
