Dual Extruder Tilt Plate for calibration
I posted new stl, and photos, I have this now installed.. and right now both my hotends appear to be dead level.

I levelled my X carriage to the Y rails.. to remove any compensation i tried earlier
calibration isnt hard., pull the bed all the way forward so the hotends are just touching the back of the bed,
loosen bottom two tilt bolts, lower hotends until they touch bed. slight pressure from lowering will make the hotends automatically tilt
until they are both touching.. you can also wiggle it until it looks level.. double check with gap tool and tighten bolts from behind and underneath and its done.
btw lego works great as a guide to level the X to the Y
