Dual Extruder Toolhead V2

I am having to rebuild the above listed tool head. Do I need a Hexagon sense lead for each Hotend. I understand that it is used for autolevel. I just want to do this right.

Thanks for any help here


Looks like just T0 from the FllexyDually assembly guide: https://ohai.lulzbot.com/project/lulzbot-taz-flexy-dually-v2-extruder/hot-end-tool-head-assembly/

Just finished the rebuild today, THEN i looked at this post. Nice bit of info Thank You, I may have to make some adjustments. we will see when I get to work.
